INTRODUCTION Common carp (Cyprinus carpi.
is one of the most important freshwater fish species in the world, with a domestication history spanning over 2,000 years.
Its native range is Eastern Europe and Asia, but it has been introduced to various regions worldwide due to its adaptability and nutritional value (Chen et al.
, 2022.
Fazli et al.
Common carp holds a prominent position among aquaculture species in terms of production According to the FAO .
, carp species represent a significant portion of global freshwater aquaculture production, especially in Asia.
Common carp is known for its ability to withstand harsh environmental conditions such as temperature fluctuations and low oxygen levels.
This adaptability has made it suitable for diverse aquaculture systems and geographic locations (Chen et al.
, 2.
These characteristics have significantly contributed to the economic importance of common carp, providing employment opportunities for millions of people, particularly in rural areas of developing countries (Yadav et al.
, 2.
Moreover, common carp is a valuable source of high-quality animal protein, rich in essential fatty acids, vitamins, and minerals, thus playing a vital role in food security in many regions (Ahmed, 2.
Another notable feature of common carp is its compatibility with various aquaculture systems, including monoculture and polyculture systems.
It is often farmed alongside other species to optimize resource utilization and enhance overall productivity.
In Iraq, meat and other sources of animal protein are often scarce or expensive making common carp a readily available and affordable source of high-quality protein.
The adaptability to diverse environmental conditions and rapid growth rate has made the common carp an ideal choice for enhancing protein supplies for Iraqi citizens.
The fish also contributes to dietary diversity as it provides essential omega-3 fatty acids, vitamins, and minerals necessary for health, particularly in rural areas where malnutrition is more prevalent (Mahmud, 2021.
FAO, 2.
Furthermore, common carp plays a vital role in IraqAos rural economy.
Small familyrun farms are often a stable source of income for rural communities, stimulating local economy by providing employment opportunities in hatchery management, fish farming, and marketing.
With increasing demand for fresh fish, carp farming has become more attractive to investors, leading to the development of largescale aquaculture, projects benefiting IraqAos economy and improving livelihoods in rural areas where job opportunities are limited (FAO.
Historically.
Iraq has heavily relied on importing fish to meet local demand.
This dependency has led to price fluctuations and supply chain disruptions that are often caused by regional instability.
Developing a domestic carp aquaculture industry can help Iraq reduce its reliance on imports, particularly benefiting lowincome groups unable to afford high import costs.
Increased local production could enable locally produced fish to compete with imports, providing a more stable supply to meet growing demand (Jawad, 2021.
Carp aquaculture in Iraq aligns with several United Nations Sustainable Development Goals (SDG.
, including Goal 2 (Zero Hunge.
and Goal 12 (Responsible Consumption and Productio.
It enhances food security, provides sustainable employment opportunities, and promotes environmentally responsible practices.
Carp farming contributes to IraqAos sustainable development agenda through government and international organization initiatives aimed at building capacity and infrastructure in the aquaculture sector (Corner et al.
, 2.
The Iraqi government and international bodies, such as the food and agriculture organization (FAO) have become increasingly involved in promoting aquaculture.
Several programs have been established to improve farm management practices, combat fish diseases, and ensure sustainable production.
These efforts include training workshops, support for fish hatcheries, and improving access to high-quality feed and fish seeds.
These programs aim to enhance IraqAos capacity for achieving self-sufficiency in fish production while reducing environmental impacts by promoting better aquaculture practices (Salman & Saleh, 2.
Historical perspective The introduction of common carp in Iraq Early Stage of Fish Introduction: Impact and Initial Efforts Before the 1950s Before the official introduction of common carp (Cyprinus carpi.
in the 1950s, fishing practices in Iraq relied primarily on traditional methods in Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
rivers, especially the Tigris and Euphrates.
The introduction of carp as a cultivated species in fish farms marked IraqAos first significant step toward organized aquaculture, representing a stark contrast to these traditional practices.
Initial government interventions Inspired by the success of carp farming in neighboring countries, the Iraqi Ministry of Agriculture began conducting preliminary experiments with common carp in the early These efforts were part of statesupported agricultural modernization plans aimed at enhancing self-sufficiency and reducing import dependency.
With the assistance of international agricultural consultants.
Iraq adopted carp aquaculture as the best candidate for this development.
The first hatcheries were established in Baghdad in 1981 (AL-Hilali et , 2.
Despite these efforts, early carp farms faced numerous challenges, including limited aquaculture knowledge among local farmers, inadequate infrastructure, and suboptimal farming techniques, resulting in low survival rates.
address these issues, the government organized training courses and demonstrations to encourage the adoption of essential farming practices and management skills among local farmers (Salman & Saleh, 2.
Expansion during the 1970s and 1980s During the 1980s, increased oil revenues from the 1970s provided Iraq with greater resources for agricultural investment including This economic prosperity allowed the government to support the construction of hatcheries and fish ponds in central and southern Iraq utilizing water from the Tigris and Euphrates rivers for aquaculture.
This period also witnessed the participation of the private sector.
Initially, state-managed farms led the development of aquaculture, but the 1970s saw a push toward private sector involvement.
The government incentivized private fish farming through low-interest loans and financial By the late 1970s, many private farms were operational, particularly in fertile areas such as Babylon.
Wasit, and Basra.
The growth of the private sector was significant as it reduced reliance on government-supplied fish and accelerated the dissemination of aquaculture knowledge.
This marked a turning point in IraqAos aquaculture history, laying the foundation for a more resilient and diversified industry (USAID, 2.
Further developments in carp hatcheries and polyculture systems In the subsequent stages of aquaculture development.
Iraq advanced its use of hatcheries and polyculture systems to support expansion.
The country established large hatcheries capable of producing millions of fingerlings annually.
Farmers were encouraged to adopt polyculture systems, raising common carp alongside other cyprinids and local fish species such as bunni (Mesopotamichthys sharpey.
This approach improved productivity and ecological balance in ponds, enabling nutrient recycling within the pond ecosystem and increasing fish yield per hectare (Jawad, 2.
Challenges of the 1980s and 1990s Iran-Iraq War .
0Ae1.
The prolonged conflict with Iran significantly affected IraqAos economy and infrastructure including the aquaculture sector.
Many carp farms suffered from neglect, and labor shortages resulted in decreased productivity.
Despite these challenges, the government attempted to support aquaculture by establishing additional hatcheries and providing assistance.
However, production remained low due to resource scarcity and limited technological advancements during the war.
(Harlioglu et al.
, 2.
Economic sanctions of the 1990s The gulf war and subsequent United Nations sanctions had devastating effects on IraqAos These sanctions severely restricted imports including essential aquaculture inputs such as high-quality feed, medicines, and pond management equipment.
As a result, many carp farms closed or reverted to low-cost practices, relying solely on natural resources.
This led to reduced production and lower fish quality.
Despite these hardships, carp farming persisted in rural communities as a necessity for survival.
Farmers innovated by utilizing locally available resources, such as agricultural by-products like rice bran as fish feed.
This period also encouraged the sharing of traditional knowledge as experienced farmers mentored beginners in managing low-cost, smallscale ponds (Mahmud, 2.
Revival post-2003 After the fall of the previous regime in 2003.
IraqAos agricultural sector as well as aquaculture encountered new opportunities for recovery through international aid and investments.
Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
Non-governmental organizations (NGO.
and international bodies including the FAO, began assisting Iraq in rebuilding its aquaculture sector.
Technical training on modern practices was provided, and rehabilitated and newly established hatcheries distributed high-quality fingerlings, gradually increasing carp production.
Research institutions, supported by international partners, launched projects that aimed at developing carp strains suited to IraqAos climatic and water These efforts focused on improving disease resistance and growth rates.
Additionally, studies on locally produced feed using ingredients like soybean and corn helped reduce feed costs and increased self-sufficiency.
Iraq also introduced biosecurity protocols to prevent the spread of diseases that had previously plagued carp farms (FAO, 2.
As illustrated in Figure 1.
IraqAos aquaculture sector has undergone three major phases: decline during the Iran-Iraq War, further deterioration under the 1990s sanctions, and gradual recovery after 2003 through international collaboration and modernization efforts.
adopted systems combining fish farming with rice cultivation which improved water quality and increased productivity.
Fish waste served as a natural fertilizer for crops while rice fields provided a suitable environment for carp.
These integrated systems created a symbiotic ecosystem, enhancing both fish and crop yields (Rasheed.
Integrated aquaculture practices Integrated aquaculture practices gained increasing acceptance, particularly in waterscarce regions such as Basra and Diyala.
Farmers Future prospects With the increasing impacts of climate change, escalating droughts, and water scarcity, common carp farmers in Iraq face significant challenges.
The Capacity building and modernization To support modernization in fish farming.
International Organizations and the Iraqi government invested in training programs for These programs covered topics such as water quality management, disease prevention, and feeding practices.
Field workshops facilitated knowledge transfer, enabling Iraqi farmers to adopt advanced techniques in an increasingly modern aquaculture sector (Jawad, 2021b.
Salman, 2011.
Jawad & Abdulsamad, 2.
This holistic approach has helped Iraq rebuild and advance its aquaculture industry, ensuring sustainable practices while supporting food security and economic growth.

, 26Ae42 .
Iraqi government, in collaboration with research institutions, is exploring closed aquaculture systems and water-saving technologies to address these issues.
Such systems enable more efficient water use which is crucial given IraqAos reliance on the Tigris and Euphrates rivers, whose water resources are managed by neighboring countries (Dyck, 2.
Rising demand and commercial expansion In recent years.
Iraq has experienced a steady rise in local demand for common carp, driven by the growth of the middle class and increased awareness of the nutritional benefits of fish.
This growing demand has attracted investments, particularly in southern Iraq, where large commercial farms have been developed to meet market needs.
Innovations in pond construction and water management have also enabled the expansion of carp farming into new areas previously unsuitable for aquaculture (FAO.
Potential for export While IraqAos primary focus remains on meeting domestic needs, the government has expressed interest in developing the aquaculture sector to eventually support fish exports.
Neighboring countries with high demand for fish represent a promising market.
Achieving export capability would not only improve food security but also contribute to economic diversification, reducing IraqAos heavy reliance on oil exports (Kitto & Tabish, 2.
By addressing water challenges, leveraging technological innovations, and fostering private and international investments.
IraqAos carp aquaculture industry has the potential to become a cornerstone of sustainable food security and economic development in the As summarized in Figure 2.
IraqAos carp aquaculture modernization has progressed through integrated systems, capacity building, and technological innovations, leading toward commercial expansion and export potential.
The cultural importance of common carp in Iraq Carp farming in Iraq: A comprehensive historical Common carp (Cyprinus carpi.
farming in Iraq has become an inseparable part of the social, cultural, and culinary fabric, especially in regions where river fish are a staple food.
Although carp farming is relatively recent compared to Figure 2.

Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
traditional fishing practices, many cultural and traditional aspects related to carp have emerged over the years, enhancing its importance in Iraqi Culinary tradition: The Iconic Dish AuMasgoufAy One of the most prominent cultural aspects associated with carp in Iraq is the traditional dish known as masgouf.
This iconic Iraqi dish is prepared by splitting the fish, seasoning it, and grilling it over an open flame, often using wood.
Masgouf is considered the national dish of Iraq and holds a central place in social gatherings and family events.
While this dish was traditionally prepared using wild-caught carp from rivers such as the Tigris and Euphrates, farmed carp has become the preferred choice with the expansion of the fish farming sector (Shabout, 2.
Cultural significance of Masgouf Masgouf is more than just a culinary dish, it represents Iraqi heritage and brings families and friends together around the grill, often in open spaces or along riverbanks.
The preparation of masgouf is inherently social, with family members participating in the cooking process, using the time to share local news and tell stories.
This cultural aspect has significantly contributed to the growing popularity of carp farming, as the demand for carp has increased, particularly in urban restaurants and households in Iraq figure 3 (Lonergan et al.
, 2.
A symbol of hospitality and generosity In Iraqi culture, serving fish, particularly carp, is a symbol of hospitality.
Due to its relative availability and affordability, carp has become a staple meal for welcoming guests, especially during holidays and special occasions.
Carp dishes are often served alongside traditional rice and bread, creating a shared dining experience that reflects the generous spirit of Iraqi hospitality.
This tradition has bolstered carp farming, as farmers strive to meet the cultural demand for readily available and high-quality fish to support family gatherings and celebrations figure 4 (Fast.

Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
Religious and ethical considerations Fish, including carp, are widely consumed in Iraq due to their compliance with religious dietary rules.
Islam permits the consumption of fish as halal, and unlike other animals, fish do not require specific slaughtering methods, making them readily accessible and permissible for Carp farming aligns with cultural and religious practices, providing an acceptable source of protein for IraqAos predominantly Muslim Carp is especially popular during the holy month of Ramadan, when many families prepare masgouf and other carp dishes for iftar .
reaking the fas.
The high demand for carp during this period led to increased production and distribution by fish farmers who recognized the cultural significance and economic opportunity associated with this time (Jawad, 2021.
local farmers together for communal harvest events in which carp are prepared, sold, or distributed among families.
This cyclical activity reinforces carp farming as a vital component of the social and economic structure of these communities, providing both financial stability and a sense of shared purpose (Fawzi et al.
, 2.
Social importance and community practices Fish farming, including carp, has evolved into a communal practice in many rural Iraqi In some regions, it is common for families or community members to jointly own fish ponds.
This shared agricultural model allows small-scale farmers to participate in carp production without requiring the full capital investment needed to own an independent fish This cooperative approach strengthens social bonds in rural areas and fosters a shared knowledge base about carp farming techniques and challenges.
Carp farms also serve as gathering places in the Iraqi countryside where farmers discuss farming methods, exchange carp for other goods, and build social networks.
This collective spirit promotes cooperation and mutual support, enhancing the role of carp farming in strengthening rural communities and providing a stable income source for many households (Agnoletti, 2.
Key areas for carp farming In the central Euphrates Region, provinces such as Babylon.
Najaf, and Karbala are hubs for carp farming due to favorable water resources.
However, the area faced a significant challenge in late 2018 when millions of carp died due to an outbreak of Koi Herpes Virus (KHV) (Ababneh et al.
, 2.
In southern provinces like Basra and Maysan have seen growth in carp farming, benefiting from extensive marshlands and suitable water bodies for aquaculture (Ahmed et al.
, 2.
Over the past two decades, the northern region Kurdistan has developed several carp farms which are now operational, contributing to economic growth and aquaculture development (Salman & Saleh, 2021.
Al-Thamir, 2.
Economic source and rural identity Carp farming in Iraq has become intertwined with local identity and economic resilience in many rural communities.
Given the economic challenges faced by Iraq, particularly in rural areas, fish farming has provided an alternative or supplementary source of income for many This economic reliance on carp farming has ingrained it into the cultural fabric of rural Iraq, where current generations view fish farming as an essential part of their livelihoods.
In some villages, seasonal events are tied to the carp farming cycle.
For example, harvest seasons bring Carp farming in Iraq: Production, key areas, and In 2020, the total fish production in Iraq has reached approximately 241,848 tons, with common carp (Cyprinus carpi.
accounting for a significant portion of this output.
The aquaculture sector has witnessed substantial growth driven by increasing demand for fish protein and efforts to enhance food security Table 1 (Harlolu et al.
Extensive carp farming in the Marshlands Dependence on natural food sources In IraqAos marshlands, particularly in southern provinces like Maysan and Basra, extensive carp farming relies on natural resources.
Fish are stocked at low densities, and feed on naturally available plankton, algae, and plant material found in the marshes and water channels (Hussain et al.
, 2.
Seasonal management Carp farming in the marshes typically occurs during periods of high water levelswhich coincide with seasonal floods.
Fish grow in these natural habitats and are harvested before water levels This approach minimizes costs but limits production due to the lower productivity of extensive systems (Verdegem et al, 2.
Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
Minimal environmental impact Extensive farming is environmentally It does not require artificial feed or additional inputs, preserving the natural ecosystem of IraqAos marshlands.
This approach aligns with conservation efforts for these ecologically sensitive areas (Abdullah et al.
, 2.
pathogens before introducing carp into main ponds or cages (Can et al, 2.
Vaccination trials Experimental trials for vaccines targeting viral and bacterial infections in carp are underway.
When successful, vaccines could become a cornerstone of biosecurity practices in Iraq, reducing reliance on antibiotics and improving fish survival rates (Razzak et al.
, 2.
Disease control and biosecurity measures Early detection programs In response to the 2018 Koi Herpes Virus (KHV) outbreak, the Iraqi government and international partners implemented disease surveillance programs in key carp farming regions.
These programs involve regular health checks and water quality testing to detect pathogens early (Bavarsad et al.
, 2.
Innovations in feeding practices and feed Local feed production To reduce dependence on imported feed.
Iraqi farmers increasingly use locally available ingredients such as rice bran, wheat by-products, and soybean residues.
These feeds are costeffective and support the local economy.
Quarantine and isolation Large farms implement quarantine protocols for new fish stock, reducing the risk of disease Quarantine tanks are equipped with filters and ultraviolet sterilizers to eliminate Supplemental feeding with high-protein meals Some farms have begun using proteinrich supplements to boost carp growth rates.

especially in intensive systems.
This ensures carp achieve optimal market weights to meet consumer demands (Jawad, 2021.
Pelleted feed trials To achieve higher production and more efficient feeding, some farms are adopting pelleted feed.
This approach reduces waste and ensures consistent nutrition for carp.
Pelleted feed has proven effective in improving feed conversion ratios, making farming practices more efficient (Zhang et al.
, 2.
These innovations and improvements demonstrate IraqAos commitment to enhancing carp farming sustainability, productivity, and economic viability.
Challenges in carp farming in Iraq Water availability Water scarcity IraqAos reliance on the Tigris and Euphrates rivers is at risk due to reduced upstream water flow resulting from dam construction in Turkey and Syria.
This decline in water flow has exacerbated water scarcity, especially in southern regions, impacting agriculture and aquaculture (Shapland.
Water quality issues Water quality has deteriorated due to agricultural runoff, industrial pollutants, and soil This degradation places additional stress on carp populations and increases the likelihood of disease outbreaks (Ewaid et al.
Competition for water resources Carp farming competes with agriculture for water resources, particularly in water-intensive This competition imposes constraints in regions where resources are limited, reducing aquaculture productivity (Elaiwi et al.
, 2.
Disease management Koi herpes virus (KHV) outbreaks The 2018 KHV outbreak in the Euphrates region caused significant carp mortality and economic losses, highlighting IraqAos vulnerability to fish diseases and the need to strengthen biosecurity measures (Toffan et al.
, 2020.
Roohi et al.
,2.
Biosecurity challenges Most small-scale farms lack the resources for essential biosecurity measures, such as quarantine facilities and water treatment systems, which are critical for preventing disease spread (Al-Salih et , 2.
Various environmental, biological, and human-related factors collectively determine the productivity and sustainability of common carp culture in Iraq.
These include water quality, water demand, disease prevalence, and management efficiency, as illustrated in Figure 5.
Environmental impacts Effects on local ecosystems Carp farming in natural water bodies can disrupt native species and alter ecosystems.
Bottom-feeding carp can increase sedimentation Figure 5.
Key factors influencing carp production and sustainability (Adla et al.
, 2.
Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
and affect aquatic plants, further impacting biodiversity (Jawad, 2021.
Nutrient enrichment and eutrophication Nutrient runoff from feed and fertilizers in intensive carp farms can cause water enrichment, leading to reduced oxygen levels and deteriorated water quality (Wojewydka-PrzybyC et al.
, 2.
Waste management Waste accumulation in intensive systems, such as floating cages, can degrade water quality and harm both farmed carp and surrounding ecosystems if not properly managed (Yang et al.
These challenges underscore the need for strategic interventions, including improved water management, advanced biosecurity measures, and environmentally sustainable practices to ensure the resilience and growth of IraqAos carp farming Regulatory challenges Lack of comprehensive regulations Iraq currently lacks a clear regulatory framework for aquaculture, leading to inconsistencies in practices related to water usage, disease control, and environmental impacts (FAO.
Water rights and distribution Laws governing water usage are unclear, resulting in competition for water resources between agriculture and aquaculture.
This ambiguity makes it challenging for farmers to secure reliable water sources (Al-Ansari, 2.
Limited support for small-scale farmers Many carp farmers in Iraq operate on a small scale with limited access to financial assistance and training programs.
Regulatory barriers often hinder their ability to expand or modernize operations (Salman & Saleh, 2.
Economic constraints and market access High input costs The costs of feed, medicine, and equipment are high, especially since many of these inputs are The lack of local fish feed production further increases production costs, limiting profitability (Mahmud, 2.
Limited market access Small-scale farmers face difficulties accessing major markets due to poor infrastructure and supply chain constraints, reducing their ability to sell locally at competitive prices (Abdulhaleem et , 2.
Post-harvest losses A lack of storage and transportation facilities leads to significant post-harvest losses, particularly in rural areas, reducing the profitability of carp farming (Yahia, 2.
Climate Change and extreme weather events Impact of rising temperatures IraqAos high summer temperatures increase evaporation rates, exacerbating water scarcity.
Elevated temperatures also stress carp, reducing growth rates and increasing vulnerability to diseases (Cordaid .
,2022.
Al-Dabbas, 2.
Drought and water scarcity Climate change is expected to increase the frequency and severity of droughts, further limiting water availability for aquaculture and intensifying the challenges of carp production in water-scarce areas (Adamo, 2.
Floods and infrastructure damage Extreme weather events, including floods, pose risks to fish farms by causing infrastructure damage and introducing contaminants into aquaculture systems (Basra, 2.
These challenges highlight the urgent need for regulatory reforms, climate adaptation strategies, and investments in infrastructure to ensure the sustainability and growth of IraqAos carp farming High costs and limited processing capacity The high costs associated with carp farming, coupled with limited processing capacity, hinder the sectorAos growth.
Export opportunities could provide a significant boost, but the current infrastructure and economic constraints limit this potential (Abdulateef et al.
, 2.
Environmental and ecological impacts of carp farming in Iraq Carp farming (Cyprinus carpi.
is a vital activity for food security in Iraq but has notable environmental and ecological consequences.
These impacts affect local ecosystems, particularly native fish species and water quality.
The extent of these effects varies based on farming intensity, the systems used, and the proximity of farms to natural water bodies.
Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
Impact on native fish species Competition and displacement Carp is a highly adaptable species that can outcompete native fish for resources such as food and space, especially when introduced into natural water bodies like IraqAos marshlands.
CarpAos bottom-feeding behavior disrupts habitats by stirring up sediments and uprooting plants, altering environments in ways that disadvantage native species (Wang et al.
, 2.
Hybridization risks In some areas, introducing carp has raised concerns about hybridization with closely related species, threatening the genetic diversity of native While this has not been widely documented in Iraq, similar cases in other regions highlight potential environmental risks (Lu et al.
, 2.
Predation on eggs and fry CarpAos omnivorous diet allows it to feed on the eggs and fry of other fish species, reducing the natural regeneration rates of native fish.
This behavior poses a significant threat to sensitive ecosystems such as the Tigris and Euphrates River systems, where some native species are already endangered due to habitat degradation and overfishing (Mohammed et al.
, 2.
Water quality and nutrient enrichment Nutrient accumulation Carp farms, particularly intensive systems, contribute to nutrient buildup in water bodies through waste production and feed residues.
This enrichment can lead to algal blooms and cyanobacteria growth, reducing oxygen levels and creating hypoxic conditions harmful to both farmed and native species (Hlavys et al.
, 2.
Sediment disturbance CarpAos bottom-feeding behavior stirs up sediments, increasing turbidity in ponds and adjacent water bodies.
High turbidity reduces light penetration, affecting aquatic plant photosynthesis and altering primary food chains.
Sediment disturbance can also bury fish eggs, degrading habitat quality for species reliant on clear waters (Huser et al.
, 2.
Chemical and antibiotic leakage In some cases, farmers use chemicals, antibiotics, and fertilizers to boost production or prevent disease outbreaks.
These substances can leach into surrounding aquatic systems, harming aquatic organisms and degrading water quality, particularly in sensitive ecosystems like IraqAos marshlands and rivers (Manyi-Loh et al.
, 2.
These environmental and ecological challenges highlight the need for sustainable practices and regulatory measures to balance carp farmingAos economic benefits with its potential environmental Changes in aquatic plants and habitat structure Destruction of aquatic plants CarpAos bottom-feeding behavior stirs up sediments and uproots aquatic plants, which serve as vital habitats for many organisms.
These plants provide food, shelter, and breeding grounds for fish and invertebrates, and their loss can significantly impact ecosystem structure and biodiversity (Mohammed et al.
, 2.
Modification of habitat complexity In natural water bodies like IraqAos rivers and marshlands, carp feeding simplifies habitat structures by removing plants and disturbing This simplification reduces the habitat complexity needed to support diverse aquatic communities and maintain fish health (Jawad.
Impact on marshland ecosystems Threat to IraqAos Marshlands The southern Iraqi marshlands are biodiversity hotspots in the region and are particularly sensitive to the introduction of carp.
Carp farming in or near these areas disrupts ecological balance by introducing non-native species and altering water The marshlands support numerous native species of fish, birds, and plants, all of which are sensitive to environmental changes caused by carp farming (Salim, 2.
Impact on endemic species Some species in IraqAos marshlands are endemic, found only in specific areas, and are threatened by the introduction of carp through competition and habitat modification.
This impact has become a significant concern for conservationists aiming to protect the unique biodiversity of IraqAos marshland ecosystems (Vilizzi et al.
, 2.
These ecological consequences underline the importance of implementing sustainable carp farming practices to mitigate negative impacts on IraqAos ecosystems, particularly its sensitive and biodiverse marshlands.
Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .
, 26Ae42 .
Solutions and sustainable practices Environmental impact assessments Conducting environmental impact assessments for farms, particularly those near sensitive ecosystems, can help mitigate negative effects.
By identifying potential environmental risks in advance, stakeholders can implement measures to minimize damage, such as guidelines for stocking densities, feed usage, and waste management (Telfer et al.
, 2.
Integrated and polyculture systems Integrating carp into polyculture systems with species occupying different ecological niches can reduce environmental impacts by creating balanced ecosystems within ponds.
Practices like rice-fish farming, already implemented in some areas of Iraq, improve resource efficiency and minimize environmental disturbances (Milstein.
Waste management and biosecurity Implementing biosecurity protocols and waste management systems, such as sedimentation ponds and filtration systems, can reduce nutrient runoff and prevent disease spread.
These practices decrease the environmental footprint of intensive carp farming systems, making them more sustainable over time (Weber & Brown, 2.
Improving the sustainability and productivity of carp farming in Iraq Enhancing the sustainability and productivity of carp farming in Iraq requires addressing several key areas, including adopting sustainable practices, strengthening genetic selection programs, and developing technologies.
These efforts can help make carp farming more efficient, resilient, and environmentally friendly.
Sustainable aquaculture practices Integrated farming systems Combining carp farming with other agricultural practices, such as rice-fish farming, optimizes land and water use.
Carp raised in rice fields benefit from natural pest control and organic fertilization from fish waste, which enhances rice productivity and reduces pesticide This system also conserves water, which is crucial in water-scarce regions of Iraq (Debnath et al.
, 2.
Polyculture systems Adopting polyculture systems by integrating carp with other fish species such as tilapia or catfish improves resource efficiency.
Each species utilizes different parts of the pond environment, reducing waste accumulation and maintaining water quality.
Polyculture also diversifies production, potentially increasing farmer incomes (Benkeblia & Radeva, 2.
Best management practices (BMP.
Implementing BMPs, such as improving feeding practices, regularly monitoring water quality, and applying biosecurity protocols, enhances productivity and sustainability.
These practices reduce nutrient runoff and minimize the risk of disease outbreaks, which is essential for protecting both farmed and wild fish populations (Saeedi et al.
, 2.
Genetic selection and breeding programs Selective breeding for rapid growth Developing genetically improved carp strains with rapid growth traits reduces the time needed to reach market size, improving productivity and profitability.
Programs focusing on growth efficiency and feed conversion ratios can greatly benefit small-scale farmers seeking quick returns (Kashyap et al.
, 2.
Disease Resistance Genetic selection for disease-resistant strains is crucial for minimizing carp susceptibility to diseases such as Koi Herpes Virus (KHV).
Disease-resistant strains significantly reduce antibiotic use, enhance survival rates, and boost farm profitability while lowering environmental impacts (Das & Sahoo, 2.
Development of local strains Developing carp strains specifically adapted to IraqAos climatic and water quality conditions can increase the resilience of farmed carp.
Research into locally adapted or regionally optimized strains may yield fish better suited to IraqAos environmental conditions, providing farmers with stocks less sensitive to temperature fluctuations and water quality issues (Dyck, 2.
These solutions represent practical and innovative approaches to overcoming the challenges of carp farming in Iraq, ensuring its long-term viability Al-Hilali HA & Lozovskiy AR / Jurnal Akuakultur Indonesia 25 .

and contribution to food security and economic deterioration and reducing disease risks (Silva et , 2.
Technological advances in aquaculture Recirculating aquaculture systems (RAS) RAS is a highly efficient system that recycles water within the farming unit, purifying it and removing waste.
This technology enables yearround production, supports higher stocking densities, and significantly reduces water use, making it ideal for water-scarce regions.
Although initial setup costs are high.
RAS reduces longterm operational expenses and minimizes environmental impact (Xiao et al.
, 2.
Use of probiotics and biofilters Probiotics are increasingly used in aquaculture to enhance water quality by balancing microbial communities and reducing harmful pathogens.
Biofilters in pond systems further purify water, improving fish health and reducing the environmental impact of water discharge (Romano, 2.
These technological advancements represent valuable opportunities for IraqAos aquaculture sector to improve sustainability, productivity, and environmental performance.
An overview of IraqAos carp production parameters and economic performance provides valuable insight into the countryAos aquaculture potential and challenges.
Key production indicators, including growth rate, survival, feed efficiency, and profitability, are summarized in Table 2.
Automated feeding systems Automated feeding systems ensure consistent and precise feeding for carp, reducing feed waste and improving feed conversion ratios.
Precision feeding can significantly lower costs, as feed typically represents the largest expense in aquaculture.
In Iraq, these systems could be particularly beneficial for large-scale farms seeking to optimize production (Harlolu et al.
Water quality monitoring tools Portable water quality testing kits and sensorbased monitoring systems provide real-time data on parameters such as pH, dissolved oxygen levels, and ammonia concentrations.
These tools allow farmers to detect changes early and make immediate adjustments, preventing water quality REFERENCE
