Fish Growth Booster Feeds Recommended by Aquaculture Experts in Ghana

At the moment of the rapid expansion of Ghana's aquaculture industry, the core competition for aquaculture efficiency has long been separated from the scale competition of aquaculture, focusing on the refined control of feed quality.According to data from the aquaculture industry in Ghana, Nile tilapia and African catfish, as the core local aquaculture varieties, occupy more than 95% of the national aquaculture production market share, while feed costs account for 60%-70% of the overall aquaculture production costs. It is the core key that determines the profitability of farmers, the growth rate of fish and shrimp, and the quality of finished products.A large number of local breeding practices have proved that poor-quality feed can directly lead to soaring bait coefficients, slow growth of fish and shrimp, and increased morbidity. It not only lengthens the breeding cycle, but also causes chain problems such as water pollution and production losses. High-quality growth-promoting feed can effectively optimize the feed conversion rate, shorten the listing cycle by about 30%, and greatly increase the return on breeding.

Combined with the local breeding scenarios in Ghana, the mainstream local breeding models are divided into three categories: Walter lake cage breeding, intensive breeding in land ponds, and intensive high-density breeding. The water temperature, water fluidity, dissolved oxygen, and breeding density of different scenarios vary greatly, and the requirements for the floatability, digestibility, and nutrient ratio of feed are very different.The water body of Walter Lake cage breeding is open and has strong fluidity, which requires higher water resistance and floating time for feed.Pond still water aquaculture is easy to accumulate residual bait, and the digestibility and low pollution attributes of feed are strictly required.Intensive high-density farming requires high-nutrient, easy-to-absorb feed to support the rapid growth of fish and shrimp.

Because of the differentiation of breeding scenarios and the core value of feed quality, Ghana's senior aquatic experts no longer refer to the purchase price of each bag of feed in the selection of materials, but a multi-dimensional comprehensive evaluation.This article will combine Ghanaian native breeding research data and first-line breeding experience to analyze high-quality growth-promoting feed suitable for Ghanaian tilapia and catfish in an all-round way to help farmers accurately select materials, feed scientifically, reduce costs and increase efficiency.

What Makes a Fish Growth Booster Feed Effective in Ghana?

Balanced protein for fast growth

Protein is the core nutrient for muscle development of tilapia and African catfish. Fish species in different breeding areas in Ghana have obvious differences in protein content and quality requirements at different stages of growth. A unified protein formula can easily cause slow growth and waste of feed.Fry have weak digestion and need a high content of easily absorbed protein.Medium-adult fish focus on muscle deposition, and the ratio is fine-tuned in the listing stage to take into account weight gain and meat quality.Many farmers in the Eastern Region and Ashanti Region did not select materials in stages, which directly reduced the overall breeding income.

Many Ghanaian farmers only look at the crude protein value on the package and ignore the protein quality.The amino acid ratio of animal-derived protein is more suitable for the needs of fish, and the absorption rate is higher than that of plant raw materials such as soybean meal and wheat bran, which reduces feces pollution of water bodies.Seedling opening material and adult fish growth material cannot be mixed. Ultra-fine and high-nutrient particles should be used for seedlings. Adult fish use water-resistant and balanced feed. Once mixed, the survival rate of fry will be reduced, resulting in uneven fish body specifications.

Energy, fat and amino acids

Energy, fat and essential amino acids work together to improve the feed conversion rate, and are adapted to the breeding model of cages and inland ponds in Lake Walter, Ghana.The fat and carbon in the feed provide basal metabolic energy, avoiding protein from being broken down for energy, and allowing all protein to be used for muscle growth.Essential amino acids such as lysine and methionine are the key to the proliferation of bones and muscles of tilapia and catfish. These ingredients are often lacking in ordinary local feed, which causes the fish to be thin, weak disease resistance, and lengthen the fattening cycle.

Ghanaian farmers should be wary of the risks posed by high-energy feed.Excess fat energy cannot be completely metabolized and will accumulate in the internal organs, weakening the fish's immunity.The unabsorbed nutrients enter the water body with the residual bait and feces, and the water quality of the cages and static ponds of Lake Walter deteriorates rapidly, and rotten gills and enteritis can easily erupt.The blind pursuit of high-fat feed cannot increase production, but instead increases the probability of diseases and increases breeding losses.

Vitamins, minerals and functional ingredients

Vitamins and minerals are the basic nutrients adapted to Ghana's changeable breeding environment.During the rainy season in Ghana, the water body is turbid and the water temperature fluctuates greatly. The breeding density of major breeding areas is uneven, and the fish are prone to stress and immunity decreases.Vitamins A, C, E, calcium, phosphorus, zinc and other minerals help bone development, reduce stress and death, and ensure the stable growth of tilapia and catfish. Whether it is intensive farming in Ashanti ponds or cage farming in Lake Walter, such nutrients cannot be lacking.

Adapted to local high-quality growth-promoting feed in Ghana, probiotics and digestive enzymes will be added to improve the problems of poor digestion and weak feeding of fish in high temperature and humidity environments, and with antioxidants to relieve high-density stress.Aquatic experts remind that functional ingredients can only be used as nutritional supplements.Inferior feed relies on a large number of attractant additives, but lacks basic nutrition, short-term feeding is active, long-term fish physique is weak, and the finished product does not meet the quality standards of the Accra and Kumasi markets.

High digestibility and palatability

Digestibility is an indicator that Ghanaian farmers often ignore, which directly affects production and cost.The high digestibility feed can be fully absorbed by tilapia and catfish, with less residual bait and excrement, which reduces the water quality pressure of cages and inland ponds in Lake Walter.Most of the nutrients of low-cost and low-quality feed cannot be absorbed. Not only is the growth slow, but the residues consume oxygen rapidly. Excessive ammonia nitrogen and nitrites in water bodies can easily cause large-scale diseases and increase the cost of medicine for farmers.

Palatability is particularly critical in the high temperature environment of Ghana, which directly affects the uniformity of fish feeding.Changes in water temperature will reduce the willingness of fish to feed, and feed with poor palatability will cause uneven feeding and serious differentiation in fish size.High-quality growth-promoting feed fits the feeding habits of tilapia and catfish, stimulating clusters to grab food.The combination of high digestion + high palatability can maintain the stability of water bodies and break the vicious circle of deterioration of water quality, loss of appetite, and stagnation of growth common in Ghanaian farms.

Fish Growth Booster Feeds Used by Ghanaian Aquaculture Farmers

Commercial tilapia feeds

As the largest fish species in Ghana, Nile tilapia has formed a mature segmented system of commercial growth-promoting feed adapted to its growth pattern. It fully fits various breeding scenarios in ponds and cages in Ghana. It is divided into three categories: seedling feed, seedling stage feed, and medium-adult fish fattening feed, which accurately matches the nutritional needs of the whole growth cycle.

In view of the mainstream Walter Lake cage farming model in Ghana, commercial tilapia feed adopts floating pellet technology, which has significant advantages.Floating particles can be suspended on the water surface for a long time, which is convenient for farmers to visually observe the feeding status of fish and shrimp, accurately judge the feeding situation, and adjust the feeding amount in time, so as to effectively avoid feed waste and water pollution caused by blind feeding, and perfectly adapt to the open breeding scene of cages.

The particle size of feed needs to strictly follow the iteration of fish body specifications. This is the core experience summarized by first-line farmers in Ghana.Ultra-fine powder and micro-granular feed are selected for the fry stage, which are suitable for the mouthparts of juvenile fish.Replace small and medium-sized particles when the juveniles grow to 3–5cm.Standard large-particle feed is used in the fattening stage of adult fish.The particle size is too large to cause the juvenile fish to be unable to feed, starvation and growth stagnation. The particle size is too small to cause low feeding efficiency and waste of feed, which directly affects the overall growth effectiveness.

Commercial catfish feeds

The growth characteristics of African catfish are significantly different from tilapia, and the requirements for feed protein, particle size, and ups and downs are more stringent, especially in the early growth stage of seedlings, the protein requirements are much higher than that of tilapia of the same specification.Catfish seedlings have a fast growth rate and vigorous metabolism. They must be fed special high-quality protein feed to meet the needs of rapid muscle development. If tilapia feed is mixed, it will directly lead to stunted seedling growth and decreased survival rate.

Catfish farming needs to follow a step-by-step particle size upgrade rule, from seedling microparticles, juvenile small particles, medium-adult fish medium particles to listed large particles, each growth stage corresponds to a unique particle size to avoid feeding problems caused by inconsistent specifications.In terms of the selection of feed ups and downs, Ghana pond stillwater aquaculture mostly uses sedimentation and slow-sedimentation catfish feed to fit the benthic feeding habits of catfish.The high-density intensive farming can be used with a small amount of floating feed to improve feeding uniformity.

Farmers need to clearly distinguish between the applicable scenarios of floating materials and submerged materials. Submerged materials fit the benthic nature of catfish, and the feeding is more natural and the stress is less.The floating material is easy to observe the feeding situation and control the feeding amount. It can be flexibly used according to the breeding density and the water environment, without the need for a single curing selection.

Locally formulated fish feeds

In order to reduce breeding costs, a large number of small and medium-sized farmers in Ghana will choose local formula feed, relying on the local production of corn, soybean meal, wheat bran, fishmeal and other raw materials independently deployed, the procurement of raw materials is convenient, the cost is low, and it is a very cost-effective feed choice in the local area.The Ghana Aquatic Scientific Research Institution has specially conducted comparative experiments to systematically compare the growth performance, survival rate and profitability of locally made formula feed and commercial finished feed for the opening stage of tilapia seedlings, which provides an authoritative reference for farmers to select types.

From the point of view of advantages, the cost of raw materials for local formula feed is low, and the ratio can be flexibly adjusted according to the growth stage of fish and shrimp. It is suitable for small-scale, low-density pond farming, and can effectively control the early breeding investment.However, the shortcomings are also very obvious. Homemade feed lacks refined process processing, insufficient nutritional ratio accuracy, low digestibility, poor water resistance, residual bait pollutes water bodies seriously, and cannot add balanced vitamins, minerals and functional ingredients. Long-term feeding will lead to uneven growth of fish and shrimp, weak disease resistance, and long breeding cycles.

Combined with the actual breeding scenarios in Ghana, the optimized local formula feed can be moderately selected for small-scale retail breeding and low-cost breeding models, and the breeding effect can be improved by accurately adjusting the protein and energy ratio.On the other hand, large-scale cage farming, high-density intensive farming, and farmers who pursue rapid market launch and high-quality finished products give priority to standardized and commercial growth-promoting feed, and the comprehensive breeding benefits are much higher than homemade feed.

How Aquaculture Experts Choose Feed for Tilapia in Ghana

Feed selection by fish size

Ghanaian aquatic experts emphasized that the core principle of tilapia feed selection is precise adaptation in stages. The physiological structure, digestive capacity, and nutritional needs of fish at different stages of growth are completely different. Targeted material selection is necessary to prevent one material from being used to the end.

• Fry and fingerling stage, the fish body is tiny, the mouthparts are slender, and the intestinal digestive function is fragile. It is necessary to choose high-precision, high-digestible, high-quality protein feed and seedling feed. The particle size is ultra-fine and the nutrition is concentrated to ensure the high survival rate and rapid growth of seedlings, and lay a good foundation for growth. The quality of feed at this stage directly determines the overall breeding yield in the later stage.
• Juvenile stage, the fish body enters the peak period of rapid growth, with a large food intake and fast metabolism. It is necessary to choose a growth feed with balanced protein, energy and amino acids, focusing on improving muscle deposition efficiency and quickly enlarging the size of the fish body. At the same time, it is matched with sufficient trace elements to enhance the disease resistance of fish and shrimp and avoid the risk of high-density breeding diseases.
• The Grow-out stage focuses on optimizing the feed conversion rate, improving the meat quality of the finished product, and fine-tuning the nutritional ratio to ensure rapid weight gain while avoiding excessive fat accumulation and improving the appearance and market value of the finished product.The whole process must follow the growth of the fish body and constantly change the particle size and formula of the feed to adapt to the growth rhythm.

Feed selection for volta lake cage farming

Lake Walter cage farming is the core farming model of tilapia in Ghana, and its output accounts for more than 80% of the total tilapia farming in the country. The water environment in this scene is special, and there are exclusive standards for feed selection and feeding control.First of all, high-quality floating growth-promoting feed is preferred. Compared with submerged materials, floating materials can be suspended on the water surface for a long time and are suitable for the open water environment of the cage to avoid the feed sinking to the bottom of the water and cannot be fed, causing waste and water pollution.

In terms of feeding control, farmers can rely on the visual advantages of floating feed to monitor the feeding response of fish and shrimp in real time, and adjust the feeding amount and feeding time in real time according to the feeding speed and feeding activity.If the feed is quickly robbed of food and the activity of fish and shrimp is high, it can be moderately increased.If feeding is slow and residual bait accumulates on the water surface, the amount needs to be reduced in time to avoid waste.

Cage breeding water bodies have strong fluidity and high breeding density, and the loss rate of feed waste is much higher than that of pond breeding. Therefore, waste control and efficiency enhancement are the core focus.The selection of floating feed with high water resistance and high digestion, coupled with accurate dynamic feeding schemes, can minimize the accumulation of residual bait, maintain stable water quality in cage water bodies, reduce the incidence of diseases, and ensure stable and high-yield large-scale aquaculture.

Feed quality vs feed price

The vast majority of farmers in Ghana have core material selection misunderstandings. They simply compare the purchase unit price of each bag of feed and give priority to low-cost feed, but ignore the comprehensive breeding cost of feed.Aquatic experts clearly pointed out that the price of a single bag is not equal to the cost of breeding, and the bait coefficient, weight gain efficiency, survival rate, and breeding cycle are the key to determining profitability.

Low-cost and low-quality feed seems to have low procurement costs, but the crude protein quality is poor, the digestibility is low, and the bait coefficient is generally high. The same weight gain requires more feed to be consumed, and it will lengthen the breeding cycle, increase the mortality rate of fish and shrimp, and increase the cost of water quality control and disease prevention and control.On the other hand, high-priced and high-quality growth-promoting feed, the purchase price of a single bag is higher, but the nutrition is balanced, the absorption is thorough, the bait coefficient is excellent, the fish and shrimp gain weight quickly, the survival rate is high, and the breeding cycle is short. Comprehensive accounting of the breeding cost per kilogram of finished fish is lower, and the profit margin is greater.

A special study on native tilapia feed in Ghana has confirmed that in the full cycle of breeding from seedlings to listing, the return on investment of high-quality growth-promoting feed far exceeds that of ordinary low-cost feed.Farmers need to abandon the low-cost thinking when choosing materials, comprehensively compare the feed conversion rate, weight gain effect, mortality rate, and breeding time, and take the cost per kilogram of fish breeding as the core standard selection, rather than just looking at the price of a single bag.

How to Choose a Fish Growth Booster Feed for Catfish

Match protein level to growth stage

African catfish have strong explosive growth and great differences in nutritional needs at different stages. Unified feed throughout the process will seriously restrict growth efficiency. Protein content must be matched strictly in accordance with the growth stage to achieve precise fattening.

• Fingerling nutrition is the period with the highest nutritional needs and the most critical growth foundation. It is necessary to feed high-quality protein special feed. The proportion of protein is higher than that of the adult fish stage, focusing on ensuring the rapid development of seedlings, improving the survival rate, and avoiding the problems of infirmity, stagnation of growth, and differentiation of size of seedlings.
• Juvenile growth, the fish body has strong metabolism and rapid muscle growth. It is necessary to maintain a balanced protein ratio of medium and high gradients, while matching sufficient amino acids and energy to help bones and muscles develop synchronously, quickly improve fish body specifications, and shorten the breeding cycle.
• Grow-out feeding can moderately fine-tune the protein ratio and optimize the energy-fat ratio. While ensuring continuous weight gain, it regulates the meat quality of the fish body to avoid excessive fat accumulation affecting the quality of the finished product, and adapts to the sales standards of the local fresh market in Ghana.

Select the right pellet size

The mouthparts and feeding habits of catfish vary significantly with body size, and the adaptability of feed particle size directly determines the feeding efficiency, which is a key point that many Ghanaian farmers can easily ignore to increase production.In the seedling stage, ultra-fine granular feed must be used, the particle size fits the mouthparts of the young fish to ensure easy feeding and no eating disorders, so as to avoid the death of the young fish from starvation and lag in growth.As the weight and body size of the fish grow, the particle size of the feed needs to be upgraded step by step. When the biomass of the fish body in the breeding water body is significantly increased and most of the fish body specifications are uniformly upgraded, the medium and large-particle feed should be replaced in time to improve the single feeding intake and breeding efficiency.

Improper adaptation of particle size can cause multiple breeding problems. If the particle size is too large, the juveniles cannot feed, and long-term starvation leads to stunted growth, physical weakness, and disparity in size.The particle size is too small, the feeding efficiency of adult fish is low, the feeding time is too long, and the feed is soaked in water for a long time, it is easy to collapse and pollute the water quality, which not only wastes feed but also increases the loss of breeding.

Monitor feeding response

Feeding status is the most intuitive indicator to judge the suitability of feed and whether the breeding environment is suitable, and it is also the core basis for the daily control of senior farmers in Ghana.In daily breeding, it is necessary to focus on observing the feeding activity of fish and shrimp, the feeding speed of clusters, and the enthusiasm for grabbing food. If the feeding of fish and shrimp is rapid, the clusters are uniform, and there is no residual bait residue, it means that the feed is adapted, the feeding amount is reasonable, and the water environment is suitable.

Conversely, if there is lazy feeding, slow feeding speed, and accumulation of residual bait on the water surface or underwater, it is either due to the palatability of the feed, the nutrient ratio is not suitable, or the feeding amount exceeds the standard, or the dissolved oxygen and water quality of the water body are problematic.The long-term retention of residual bait in water bodies will quickly decompose and deteriorate the water quality, resulting in excessive ammonia nitrogen and nitrite, further inhibiting the appetite of fish and shrimp, and forming a vicious circle of growth.Farmers need to dynamically adjust the total amount of feeding according to the growth of fish biomass, changes in water temperature, and water quality conditions, take samples and weigh regularly, and optimize the feeding plan based on weight growth data to ensure that fish and shrimp are always in the best feeding and growth state.

Lima Biotech Fish Growth Booster for Catfish

In the process of catfish breeding, high-quality feed is the basis for ensuring growth, but in high-density breeding, rapid fattening, and later stages of the breeding cycle, relying only on basic feed is sometimes difficult to meet the nutritional needs of the fish's continuous and rapid growth.Reasonable matching of professional fish growth promoting agents can further improve the efficiency of feed utilization and help farmers optimize the overall breeding effect.
