# Catfish Feeding and Diet: Natural Food and Supplemental Feed Management ## Key Takeaways - Catfish farming necessitates a dual feeding strategy, integrating natural food organisms (algae, zooplankton, insects) for fry and fingerlings with supplemental formulated feeds as the primary growth driver for market-size fish. Natural food contributes to base nutrition and adult maintenance, while supplemental feeds constitute 50-70% of variable costs and are crucial for consistent nutrient intake and growth. - Pond productivity management, including fertilization to stimulate phytoplankton and zooplankton, is critical for supporting natural food availability. Moderate phytoplankton blooms, indicated by Secchi disk visibility of 30-45 cm, are optimal; excessive blooms (below 20 cm) risk oxygen depletion, while low productivity (above 60 cm) may require fertilization. - Supplemental feed management requires matching feed size to fish mouth gape and adjusting feeding rates based on water temperature (optimal 25-30°C, reduced below 15°C or above 35°C) and dissolved oxygen levels (feeding stopped below 3 mg/L). Feed formulations vary by life stage, with fry feeds typically containing 35-40% protein and grower feeds 28-32%. - Daily monitoring of feeding behavior is essential; feed consumed within 15-20 minutes indicates adequate ration, while feed remaining after 30 minutes signifies overfeeding and potential water quality degradation. Maintaining accurate records of feed input, consumption, water quality, and growth performance allows for calculation of feed conversion ratios (typically 1.5-2.0 for channel catfish) and informed adjustments. - Common feeding failures include overfeeding leading to water quality degradation (low dissolved oxygen, high ammonia), underfeeding causing stunted growth and size variation, ignoring natural food contributions, feeding during stress periods (poor water quality, disease), and using inappropriate feed sizes. - A hybrid feeding approach, adjusting between natural food maximization for early stages and complete supplemental feeding for grow-out, is often most effective. This strategy balances feed costs, growth rates, and production efficiency, with careful consideration of stocking density, pond infrastructure, and economic constraints. --- [Catfish farming](/knowledge/animal-farming/aquaculture/catfish-farming-managing-the-production-cycle-from-stocking-to-harvest) requires a feeding strategy that balances natural food organisms with supplemental formulated feeds to control costs while supporting growth and health. This article provides catfish farmers with practical guidance on managing pond productivity, understanding natural food contributions, and implementing supplemental feeding programs based on available evidence from aquaculture research and official sources. ## At a Glance: Natural Food and Supplemental Feed Roles in Catfish Production | Feeding Component | Primary Role | Management Consideration | Cost Implication | |-------------------|--------------|------------------------|------------------| | Natural food organisms (algae, zooplankton, insects) | Base nutrition for fry and fingerlings, contributes to adult maintenance | Maintain water quality and pond fertility, avoid overstocking that depletes natural food | Low direct cost, requires pond management labor | | Supplemental formulated feeds | Primary growth driver for market-size fish, ensures consistent nutrient intake | Match feed size to fish mouth gape, adjust feeding rate based on water temperature and dissolved oxygen | Major operational expense, 50-70% of variable costs | | Combined system | Optimizes growth rate and [feed conversion ratio](/knowledge/animal-farming/poultry/feed-conversion-ratio-measuring-improving-poultry-efficiency) | Monitor feeding behavior and pond productivity, reduce feed when natural food is abundant | Balances cost and growth efficiency | ## Understanding Catfish Natural Feeding Behavior Catfish species display diverse feeding strategies that influence how they utilize natural food organisms. The Chinese longsnout catfish genome provides novel insights into the feeding preference and corresponding metabolic strategy of carnivores, indicating that genetic factors shape dietary adaptations in catfish species. Farmers managing multiple species or considering new catfish types should recognize that feeding behavior varies across genetic lines. Channel catfish and other commercially farmed species are opportunistic omnivores. In pond environments, they consume algae, aquatic insects, crustaceans, worms, and small fish when available. Natural food organisms contribute significantly to the diet of fry and fingerlings, providing essential nutrients that support early development. As fish grow larger, their reliance on natural food decreases, but these organisms continue to supplement nutrition and reduce feed costs. Observations of feeding behavior at the pond bank provide practical information. Fish that actively feed at the surface on floating feed indicate good appetite and health. Fish that remain near the bottom or show reduced feeding activity may be consuming natural food or experiencing stress from poor water quality. Farmers should record feeding response daily and note any changes that might signal problems. The FAO provides information on cultured species through its fisheries and aquaculture programs, which farmers can reference for species-specific feeding guidance. Understanding the natural feeding ecology of the catfish species being farmed helps farmers design pond management and feeding programs that work with the fish's biology instead of against it. ## Natural Food Organisms in Catfish Ponds ### Algae as a Dietary Component Algae form the base of the pond food web and contribute directly and indirectly to catfish nutrition. Phytoplankton blooms produce oxygen through photosynthesis and serve as food for zooplankton, which catfish consume. Some catfish species also graze directly on filamentous algae and attached periphyton. The question of whether catfish eat algae depends on the species and life stage. Fry and small fingerlings consume algae and other microorganisms as part of their natural diet. Adult catfish may ingest algae incidentally while feeding on other organisms, but they do not rely on algae as a primary nutrient source. Pond management that maintains moderate phytoplankton blooms supports natural food production without causing oxygen depletion. Farmers can assess algal abundance using a Secchi disk. Visibility readings between 30 and 45 centimeters indicate moderate phytoplankton levels that support natural food production. Readings below 20 centimeters suggest excessive blooms that risk oxygen crashes, while readings above 60 centimeters indicate low productivity that may require fertilization. ### Zooplankton and Benthic Organisms Zooplankton, including rotifers, copepods, and cladocerans, are critical natural food items for catfish fry and early fingerlings. These organisms provide high-quality protein and essential fatty acids that formulated feeds may not fully replicate. Benthic organisms such as chironomid larvae, oligochaete worms, and amphipods contribute to the diet of larger fish. Pond management practices that support zooplankton populations include maintaining organic matter inputs, avoiding excessive aeration that disrupts stratification, and managing fish stocking densities. Overstocking depletes natural food organisms faster than they can reproduce, forcing fish to rely entirely on supplemental feed. Farmers can monitor zooplankton abundance by collecting water samples with a plankton net and examining them under a simple microscope or magnifying glass. Regular sampling every two weeks during the growing season provides data on natural food availability and helps guide feeding decisions. ### Pond Productivity Management Pond fertilization can increase natural food production, but farmers must balance nutrient inputs against water quality risks. Organic fertilizers such as manure or inorganic fertilizers such as urea and phosphates stimulate phytoplankton growth, which supports zooplankton populations. The FAO Animal Production and Health division provides resources on sustainable aquaculture practices that include pond management guidance. Excessive fertilization causes algal blooms that collapse and deplete oxygen. Farmers should apply fertilizers in small, frequent doses instead of large single applications. Water exchange or aeration may be necessary to maintain oxygen levels during periods of high productivity. ## Supplemental Feed Management ### Feed Types and Formulations Commercial catfish feeds are formulated to provide complete nutrition when natural food is limited. Floating pellets are standard for channel catfish production because they allow farmers to observe feeding activity and adjust rations accordingly. Sinking feeds may be appropriate for some species or production systems but make feeding observation more difficult. Feed formulations vary by fish size and production stage. Fry feeds contain higher protein levels, typically 35-40%, and smaller particle sizes. Grower feeds for larger fish contain 28-32% protein. Farmers should select feeds that match the nutritional requirements of their fish at each life stage. The use of alternative protein sources in catfish feeds is an area of active research. Aquaculture wastewater-raised Azolla as partial alternative dietary protein for Pangasius catfish has been investigated, suggesting that plant-based proteins may partially replace fishmeal in some catfish diets. Farmers considering alternative feed ingredients should evaluate cost, availability, and nutritional adequacy before making changes. The USDA Agricultural Research Service conducts research on aquaculture production and protection, including feed development and nutrition. Farmers can access findings from this research through extension publications and industry meetings. ### Feeding Rates and Schedules Feeding rates depend on fish size, water temperature, dissolved oxygen levels, and natural food availability. General guidelines suggest feeding 3-5% of body weight daily for fingerlings and 1-3% for grow-out fish. These rates should be adjusted based on observed feeding behavior and growth performance. Water temperature directly affects catfish metabolism and feed intake. Feeding should be reduced or stopped when water temperatures fall below 15°C or exceed 35°C. Optimal feeding occurs at temperatures between 25°C and 30°C. Farmers should record daily water temperature and adjust feed amounts accordingly. Dissolved oxygen levels influence feeding activity and feed conversion. Fish should not be fed when dissolved oxygen is below 3 mg/L. Feeding during early morning hours when oxygen levels are lowest can cause stress and reduce feed efficiency. The best practice is to feed after oxygen levels have risen, typically mid-morning to early afternoon. ### Feed Observation and Adjustment Farmers should observe feeding behavior at each feeding event. Fish that consume all feed within 15-20 minutes may require a larger ration. Feed remaining after 30 minutes indicates overfeeding, and the ration should be reduced. Uneaten feed decomposes and degrades water quality, increasing oxygen demand and ammonia levels. Records of feed input, feeding response, and water quality parameters allow farmers to calculate feed conversion ratios and adjust management. A [feed conversion ratio](/knowledge/animal-farming/poultry/feed-conversion-ratio-measuring-improving-poultry-efficiency) of 1.5 to 2.0 is typical for channel catfish under good management. Higher ratios indicate feed waste or poor conversion that requires investigation. ## Practical Implementation Steps ### Step 1: Assess Pond Productivity Measure Secchi disk visibility weekly during the growing season. Collect water samples for phytoplankton and zooplankton identification every two weeks. Record observations of natural food abundance and note any changes that might affect feeding management. ### Step 2: Determine Feed Requirements Calculate total fish biomass in each pond based on stocking records and periodic sampling. Use growth charts or sampling data to estimate average fish weight. Multiply biomass by the appropriate feeding rate percentage to determine daily feed requirement. ### Step 3: Establish Feeding Schedule Divide daily feed ration into two feedings when possible. Feed at the same times each day to establish a feeding routine. Avoid feeding during periods of low dissolved oxygen or extreme temperatures. ### Step 4: Monitor and Adjust Observe feeding behavior at each feeding. Record feed amount offered, time to consumption, and any feed remaining. Adjust rations based on observations and water quality data. Reduce feed when natural food is abundant or when fish show reduced appetite. ### Step 5: Evaluate Growth Performance Sample fish every two to four weeks to measure growth. Weigh a representative sample of at least 30 fish per pond. Calculate average weight gain and feed conversion ratio. Compare results to targets and adjust feeding strategy as needed. ## Records and Measurements Maintaining accurate records is essential for effective feed management. The following data should be recorded for each pond: | Parameter | Recording Frequency | Purpose | |-----------|---------------------|---------| | Feed amount offered and estimated consumption | Daily | Calculate feed conversion ratio, adjust rations | | Water temperature at feeding time | Daily | Determine metabolic rate, adjust feeding rate | | Dissolved oxygen level at feeding time | Daily | Assess feeding suitability, avoid stress | | Secchi disk visibility | Weekly | Monitor phytoplankton abundance, natural food production | | Feeding behavior score (active, moderate, poor) | Daily | Detect health or water quality problems early | | Unusual observations (dead fish, disease signs, water color changes) | As needed | Trigger investigation and corrective action | Weekly records should include average fish weight from sampling, feed conversion ratio calculation, total feed input for the week, water quality parameters (pH, ammonia, nitrite), weather conditions, and any management actions. Monthly records should include growth rate calculation, survival estimate, total feed cost, and any disease treatments or water quality interventions. These records allow farmers to identify trends and make informed management decisions. Comparing data across ponds and production cycles helps refine feeding strategies and improve efficiency. ## Common Failure Patterns in Catfish Feeding ### Overfeeding and Water Quality Degradation The most common feeding error is providing more feed than fish can consume. Excess feed decomposes in the pond, consuming oxygen and producing ammonia. This leads to low dissolved oxygen, elevated ammonia levels, and increased disease risk. Farmers who observe feed remaining after 30 minutes should reduce the next ration by 10-20%. ### Underfeeding and Stunted Growth Underfeeding results in slow growth, variable fish sizes, and extended production cycles. Fish that compete for limited feed may show size variation and increased aggression. Farmers should monitor growth rates and increase feed amounts when fish show strong feeding response and consume all feed quickly. ### Ignoring Natural Food Contributions Farmers who rely entirely on supplemental feed without considering natural food availability may overfeed when natural food is abundant. This wastes feed and degrades water quality. Conversely, farmers who assume natural food will meet all nutritional needs may underfeed and achieve poor growth. Regular assessment of pond productivity helps balance these inputs. ### Feeding During Stress Periods Feeding fish during periods of low dissolved oxygen, high ammonia, or disease outbreaks increases stress and reduces feed efficiency. Farmers should reduce or stop feeding when water quality parameters are outside optimal ranges. Resuming feeding only after conditions improve supports better health and growth. ### Inappropriate Feed Size Feeds that are too large for fish mouth gape cause feed waste and poor growth. Feeds that are too small may not be consumed efficiently by larger fish. Farmers should match feed particle size to fish size and adjust as fish grow. ## Welfare and Safety Context ### Fish Welfare Considerations Proper feeding management supports fish welfare by reducing competition, stress, and disease. Fish that receive adequate nutrition show better immune function and resistance to pathogens. Underfeeding causes chronic stress and increases susceptibility to infections. Overfeeding degrades water quality and creates conditions that favor disease outbreaks. Feeding behavior is an important welfare indicator. Fish that refuse feed or show reduced feeding activity may be experiencing stress from poor water quality, disease, or handling. Farmers should investigate the cause of reduced feeding and take corrective action before problems escalate. The USDA National Agricultural Library provides resources on animal health and welfare that include aquaculture welfare considerations. Farmers can reference these materials when developing welfare protocols for their operations. ### Worker Safety Feed handling and storage present safety considerations for farm workers. Feed bags are heavy and can cause back injuries if lifted improperly. Workers should use proper lifting techniques and mechanical assistance when moving large quantities of feed. Feed storage areas should be clean, dry, and free of pests to prevent contamination and spoilage. Workers who handle medicated feeds should follow label instructions and use appropriate personal protective equipment. Medicated feeds contain antibiotics or other drugs that can cause skin irritation or allergic reactions in sensitive individuals. ### [Food Safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention) Feed management directly affects [food safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention) in catfish production. Withdrawal periods must be observed when using medicated feeds to prevent drug residues in market fish. Farmers should maintain records of all feed inputs, including medicated feeds, and follow label instructions for withdrawal times. The use of alternative feed ingredients requires attention to food safety. Poultry by-product feeding as a vector for antibiotic residues and microbiota shifts in yellow catfish aquaculture has been documented, indicating that feed ingredients can introduce contaminants into the production system. Farmers should source feeds from reputable manufacturers and verify ingredient quality. ## Limitations and Professional Escalation ### When to Seek Professional Advice Farmers should consult with aquaculture extension specialists or feed company nutritionists when: - Feed conversion ratios exceed 2.5 for extended periods - Fish show poor growth despite adequate feeding - Water quality problems persist despite management adjustments - Disease outbreaks occur repeatedly - Alternative feed ingredients are being considered Extension specialists can provide site-specific recommendations based on local conditions and research. Feed company nutritionists can help formulate feeds that match specific production goals and constraints. ### Regulatory Considerations Feed regulations vary by jurisdiction. Farmers should ensure that all feeds used are approved for aquaculture in their region. Medicated feeds require veterinary oversight in many areas. Farmers should maintain records of feed purchases and usage to demonstrate compliance with regulations. The USDA Agricultural Research Service provides information on aquaculture production and protection through its research programs. Farmers can access this information through extension services and online resources. ### Production System Limitations Different production systems have different capacities for natural food production. Ponds with low water exchange support more natural food organisms than high-flow systems. Recirculating aquaculture systems provide minimal natural food and require complete reliance on formulated feeds. Farmers should adjust feeding strategies based on their production system type. Research on aquacultural production systems provides context for understanding how system design affects feeding management. Farmers should consider system limitations when developing feeding programs. ## Comparing Feeding Strategies: Natural Food Maximization Versus Complete Supplemental Feeding Catfish farmers face a fundamental decision about how to allocate resources between managing pond productivity for natural food and relying on formulated feeds. Two distinct approaches exist, and the choice between them depends on production goals, pond infrastructure, and economic constraints. Understanding the trade-offs between these strategies helps farmers make informed decisions that match their specific circumstances. ### Natural Food Maximization Strategy The natural food maximization approach prioritizes pond management practices that support high levels of phytoplankton, zooplankton, and benthic organisms. Farmers using this strategy invest labor in pond fertilization, water quality management, and stocking density control to maintain productive aquatic food webs. This strategy works best for fry and fingerling production, where natural food organisms provide essential nutrients that support early development. Fry consuming natural zooplankton show better survival rates and more uniform growth compared to those relying solely on formulated feeds. The approach also reduces feed costs during early production stages when fish are small and feed conversion is less efficient. Pond management for natural food maximization requires regular monitoring of phytoplankton blooms using Secchi disk measurements. Farmers target visibility readings between 30 and 40 centimeters, which indicate moderate algal productivity. Fertilization with inorganic fertilizers at rates of 5-10 kg nitrogen per hectare per week supports phytoplankton growth without causing excessive blooms. Organic fertilizers such as chicken litter at 100-200 kg per hectare every two weeks provide both nutrients and organic matter that support benthic organisms. The limitations of this strategy become apparent as fish grow larger. Adult catfish require more protein and energy than natural food alone can provide. Fish stocked at commercial densities quickly deplete natural food organisms, forcing reliance on supplemental feed. Farmers who attempt to maximize natural food for grow-out fish often achieve slower growth rates and longer production cycles. ### Complete Supplemental Feeding Strategy The complete supplemental feeding approach treats formulated feed as the primary nutrient source and manages ponds primarily for water quality instead of natural food production. Farmers using this strategy stock fish at higher densities and rely on commercial feeds to meet all nutritional requirements. This strategy supports higher stocking densities and more predictable growth rates. Fish receive consistent nutrition regardless of seasonal changes in pond productivity. Feeding behavior observation becomes more reliable because fish depend entirely on offered feed and show clear responses to ration changes. Pond management under this strategy focuses on maintaining water quality instead of supporting natural food. Aeration systems are often necessary to maintain dissolved oxygen levels at high stocking densities. Water exchange rates may be higher to remove waste products. Secchi disk readings below 20 centimeters indicate excessive phytoplankton that requires management instead of desirable productivity. The main disadvantage of complete supplemental feeding is higher feed costs. Feed represents 50-70% of variable production costs in intensive catfish operations. Farmers using this strategy must achieve good feed conversion ratios to remain profitable. The strategy also requires more capital investment in aeration and water management infrastructure. ### Hybrid Approach: Seasonal and Life Stage Adjustment Most commercial catfish operations use a hybrid approach that adjusts feeding strategy based on fish life stage and seasonal conditions. This approach captures the benefits of both strategies while minimizing their disadvantages. During the first 4-6 weeks after stocking fry, farmers emphasize natural food production through pond fertilization and careful stocking density management. Fry receive small amounts of high-protein starter feed to supplement natural food. This period builds the pond food web and supports rapid early growth at low feed cost. As fish reach fingerling size and stocking densities increase, farmers gradually shift toward supplemental feeding. Natural food continues to contribute to nutrition but becomes less important as fish grow. Farmers reduce fertilization rates to prevent excessive algal blooms that could cause oxygen problems at higher feeding rates. During summer months when water temperatures support optimal growth, farmers rely primarily on formulated feeds. Natural food contributions are minimal at this stage, and feeding rates are adjusted based on observed consumption and growth. Farmers monitor water quality closely because high feeding rates increase oxygen demand and waste production. In spring and fall when water temperatures are suboptimal for growth, farmers may reduce feeding rates and allow natural food to contribute more to fish nutrition. This reduces feed costs during periods when feed conversion is less efficient. Pond fertilization may resume to support natural food production during these transitional periods. ### Decision Framework for Strategy Selection Farmers should evaluate the following factors when choosing a feeding strategy: | Factor | Natural Food Maximization | Complete Supplemental | Hybrid Approach | |--------|--------------------------|----------------------|-----------------| | Fish life stage | Fry and fingerlings | Grow-out and market | All stages | | Stocking density | Low to moderate | High | Moderate to high | | Pond infrastructure | Basic, limited aeration | Full aeration, water exchange | Moderate aeration | | Labor investment | High for pond management | Moderate for feeding | Moderate to high | | Feed cost per kg fish | Low | High | Moderate | | Growth rate predictability | Variable | Consistent | Good | | Risk of oxygen depletion | Moderate | High | Moderate | Farmers with limited capital for aeration and water management infrastructure should emphasize natural food production and maintain lower stocking densities. Farmers with well-equipped ponds and access to quality feeds can pursue more intensive feeding strategies. The hybrid approach offers flexibility for farmers who want to balance costs and production efficiency. ### Records for Strategy Evaluation Farmers should maintain records that allow comparison of feeding strategies across ponds and production cycles. Key metrics include: - Feed conversion ratio calculated monthly and at harvest - Feed cost per kilogram of fish produced - Average daily gain during different production periods - Survival rate from stocking to harvest - Size uniformity at harvest Comparing these metrics across ponds managed with different strategies helps farmers identify the most cost-effective approach for their specific conditions. Records from multiple production cycles provide data for refining feeding strategies over time. ### Common Failure Patterns in Strategy Selection Farmers who commit exclusively to natural food maximization for grow-out production often achieve slow growth and extended production cycles. Fish may reach market size weeks or months later than expected, increasing labor costs and delaying revenue. This approach works only at very low stocking densities that are rarely economically viable. Farmers who rely entirely on supplemental feeding without managing pond productivity may experience water quality problems that reduce feed efficiency. High feeding rates without adequate aeration or water exchange lead to oxygen depletion and ammonia accumulation. Fish may show reduced feeding activity and poor growth despite receiving adequate feed. The most common failure is inconsistent strategy application. Farmers who switch between approaches without clear planning may overfeed during periods of high natural food abundance or underfeed when natural food is depleted. Regular monitoring and record keeping help farmers maintain consistent management. ## Frequently Asked Questions ### Do catfish eat algae? Catfish fry and small fingerlings consume algae as part of their natural diet. Adult catfish may ingest algae incidentally but do not rely on it as a primary nutrient source. Algae support the pond food web by producing oxygen and feeding zooplankton, which catfish consume. ### What is the best feed for catfish? Commercial floating pellets formulated for catfish provide complete nutrition for grow-out production. Fry require higher protein feeds with smaller particle sizes. Farmers should select feeds that match the nutritional requirements of their fish at each life stage and source from reputable manufacturers. ### How often should I feed catfish? Feeding once or twice daily is standard for catfish production. Two feedings per day may improve growth rates and feed conversion compared to single feedings. Feeding at the same times each day establishes a routine that supports consistent feeding behavior. ### How much should I feed my catfish? Feeding rates of 3-5% of body weight daily for fingerlings and 1-3% for grow-out fish are general guidelines. Actual amounts should be adjusted based on observed feeding behavior, water temperature, dissolved oxygen levels, and natural food availability. ### Can catfish survive on natural food alone? Catfish can survive on natural food alone but will grow slowly and reach market size later than fish receiving supplemental feed. Natural food production is limited by pond productivity and [fish stocking density](/knowledge/animal-farming/aquaculture/fish-stocking-density-how-to-make-a-responsible-decision). Supplemental feed is necessary for commercial production to achieve acceptable growth rates and production cycles. ### What water temperature is best for feeding catfish? Optimal feeding occurs at water temperatures between 25°C and 30°C. Feeding should be reduced when temperatures fall below 20°C and stopped below 15°C. High temperatures above 35°C also reduce feeding activity and may cause stress. ### How do I know if I am overfeeding my catfish? Feed remaining in the pond 30 minutes after feeding indicates overfeeding. Fish that show reduced feeding activity or swim away from feed may also indicate excessive rations. Overfeeding degrades water quality and increases production costs. ### What records should I keep for feed management? Daily records of feed amount offered, estimated consumption, water temperature, dissolved oxygen, and feeding behavior are essential. Weekly records of fish weight, feed conversion ratio, and water quality parameters support informed management decisions. Monthly records of growth rate, survival, and feed costs allow evaluation of production efficiency. ## Related Farming Guides - [Raceway Fish Farm Management Flow Solids Feeding And Emergency Response](/knowledge/animal-farming/aquaculture/raceway-fish-farm-management-flow-solids-feeding-and-emergency-response) - [Aquaculture Algal Bloom Management](/knowledge/animal-farming/aquaculture/aquaculture-algal-bloom-management) - [Pullet Rearing Management For Laying Hens](/knowledge/animal-farming/poultry/pullet-rearing-management-for-laying-hens) - [Freshwater Prawn Farming Stocking Shelter Feeding And Harvest Management](/knowledge/animal-farming/aquaculture/freshwater-prawn-farming-stocking-shelter-feeding-and-harvest-management) - [Varroa Mite Monitoring And Integrated Management](/knowledge/animal-farming/apiculture/varroa-mite-monitoring-and-integrated-management) ## Related Clinical & Scientific Guides * [Pond Sediment Management and Dredging Options](/knowledge/animal-farming/aquaculture/pond-sediment-management-dredging-options) * [Indoor Aquaculture Facilities: Lighting and Insulation](/knowledge/animal-farming/aquaculture/indoor-aquaculture-facilities-lighting-insulation) * [Greenhouse Aquaculture: Extending Growing Seasons](/knowledge/animal-farming/aquaculture/greenhouse-aquaculture-extending-growing-seasons) ## References and Further Reading - [www.fao.org](https://www.fao.org/fishery/en/culturedspecies) - [www.ars.usda.gov](https://www.ars.usda.gov/animal-production-and-protection/aquaculture) - [FAO Animal Production and Health](https://www.fao.org/animal-production/en).
