How to Choose Fish Feed Additives in 2025?

In aquaculture, the proper selection of fish feed additives has a direct impact on aquaculture profitability and fish health. 2025 will bring new challenges and opportunities for additive selection as a result of changing market demands and technological innovations.

Importance of Fish Feed Additives in Aquaculture

Important Role of Fish Feed Additives

Fish feed additives play an irreplaceable and critical role in the whole process of aquaculture. From the perspective of fish growth, the scientific addition of amino acids, vitamins and other nutritional additives in feed can significantly shorten the breeding cycle. According to authoritative research data, the reasonable addition of lysine and methionine in carp feed can increase the growth rate of carp by 15% - 20%, which greatly improves the breeding efficiency.

In terms of enhancing immunity, antioxidants such as vitamin C and E can not only enhance the immune function of fish, but also effectively reduce the incidence of diseases triggered by environmental stress (such as sudden changes in water temperature and deterioration of water quality). Take tilapia farming as an example, adding appropriate amount of vitamin C to feed can increase the disease resistance of tilapia by 30% during the high temperature season and reduce the risk of farming.

At the same time, additives can also improve feed utilization significantly. Suitable enzymes can help fish better digest the nutrients in the feed and reduce the waste of nutrients. For example, adding amylase and protease to shrimp and crab feed can increase the feed conversion rate by 10% -15% and reduce farming costs. In addition, some additives can also improve the flavor and quality of fish, to meet consumer demand for high-quality aquatic products, and enhance the competitiveness of the product market.

Types of fish feed additives

Nutritional additives

Amino acids: Amino acids are the basis of protein synthesis in fish. Adding essential amino acids, such as lysine and methionine, to fish feed can effectively meet the growth demand of fish and improve protein utilization.

Minerals: Minerals are essential for fish's bone development, enzyme activity and other physiological functions. Calcium, phosphorus and other macronutrients as well as iron, zinc and other trace elements should be kept in reasonable proportion in the feed.

Vitamins: Vitamins are classified into fat-soluble and water-soluble. Vitamin C enhances fish immunity, Vitamin D helps in calcium absorption and Vitamin E is an antioxidant.

Non-nutritive additives

Antioxidants: Antioxidants are effective in preventing oxidative deterioration of feed and protecting fish from free radicals. Vitamin E and some synthetic antioxidants are common.

Preservatives: Preservatives can extend the shelf life of feed and prevent microbial contamination. Selection of safe and efficient preservatives is the key to ensure feed quality.

Growth promoters: Natural fish growth promoters, such as probiotics and prebiotics, can regulate the intestinal flora of fish and improve their digestive ability; while the use of synthetic growth promoters needs to strictly follow the relevant regulations.

Food attractants and palatability enhancers: Amino acid and flavor attractants can improve the feeding motivation of fish and increase feed intake.

Key Considerations for Selecting Fish Feed Additives in 2025

Fish Species and Growth Stages

The dietary and nutritional requirements of different fish species vary significantly. Carnivorous fish (e.g. perch, mandarin fish) have higher protein and fat requirements, and the selection of additives should emphasize the balance of amino acids and high quality fats. Herbivorous fish (e.g. grass carp, bream), on the other hand, require more enzymes such as cellulase to help digest plant feeds. Omnivorous fish (e.g. crucian carp, carp) have more complex nutritional requirements and require a combination of multiple nutrients.

At the same time, fish have different needs for additives at different growth stages. The juvenile stage is the key period of growth and development, and the demand for nutrients such as vitamins, minerals and amino acids is more urgent. For example, adding an appropriate amount of DHA and ARA to the open feed for fry can help the development of their brain and retina and improve their survival rate. In the adult stage, more attention is paid to the additives to improve fish quality and immunity.

Cost-effectiveness

When selecting additives, it is important to consider their costs and benefits. Although some high-performance additives are more expensive, they may be more cost-effective in the long run. For example, although a high-quality probiotic additive has a higher unit price, it can improve feed conversion rate, reduce the occurrence of diseases, lower farming costs and ultimately bring higher returns. In practice, cost-benefit analysis can be conducted by comparing the price and performance of different additives. At the same time, pay attention to the market dynamics and price fluctuations of additives, and reasonably adjust the procurement strategy to achieve effective cost control.

Selecting fish feed additives in 2025 is a complex and critical task, which requires comprehensive consideration of various factors such as fish species, growth stages, and cost-effectiveness. Evaluate the performance of additives through scientific research and field trials, and rationally apply them in feed formulations. At the same time, we should pay attention to the future trend of the industry and select sustainable and precise fish feed additive products. Only in this way can we realize efficient and sustainable development in aquaculture, meet the market demand for high-quality aquatic products, and promote the aquaculture industry to new heights.
