Feed additives to improve aquaculture nutrition

Aquaculture nutrition supplements for maximum performance and efficiency

Aquaculture is one of the fastest developing forms of animal production in the world. This growth comes with a series of challenges surrounding environmental sustainability, animal welfare and profitability.

Products and services, backed by science, to help you solve your toughest challenges, like:

At Alltech, our aquaculture specialty ingredients work to solve your toughest challenges.

Backed by over 40 years of research and real customer success, Alltech’s specialty feed ingredients and Alltech Coppens aquafeeds offer superior nutritional solutions for fish and shrimp. 

Disease is a significant threat to successful aquaculture. Pathogenic parasites, bacteria and viruses can cause health problems and death, slowing production significantly. Tackling these issues with vaccines, antibiotics or other chemicals may not be desirable or possible.

Aquaculture specialty feed ingredients are essential tools to help fish combat pathogens. They promote well-balanced microflora in the digestive system, keeping fish healthy so you can maximize your production yield and increase your profitability.

Alltech improves performance and efficiency for several species of fish and other marine animals.

Alltech services can help you with your toughest challenges.

Types of aquaculture feed additives

There are several types of aquaculture feed additives, including:

  • Phytogenic compounds: Phytogenic compounds are plant derivatives from leaves, roots, fruits and other plant parts. They have a range of beneficial characteristics, including antioxidant, antimicrobial, insecticidal and more.
  • Microalgae: Microalgae are photosynthetic microorganisms that support nutrition and growth performance. They are an excellent source of protein, fat, vitamins and antioxidants.
  • Yeast: Certain yeast species are used in aquaculture to enhance fish growth and help boost their immune systems. Yeast provides a high amount of vitamin B, fatty acids and amino acids.
  • Enzymes: Enzymes can increase growth, feed conversion ratios and energy levels in various fish species. Common aquaculture feed enzymes include phytase, pepsin and lipase.
  • Organic acids: Organic acids enhance nutrient use, disease resistance and growth in fish. They decrease pH levels in the stomach and intestine while increasing digestive enzyme activity. Examples include citric acid, lactic acid, sorbic acid and benzoic acid.
  • Probiotics: Probiotics are live microbes that can support intestinal microbial balance in fish. They can also enhance water quality in aquaculture systems.
  • Prebiotics: Prebiotics are indigestible ingredients that stimulate the growth and activity of certain bacteria species to help support fish health. Common aquaculture prebiotics include inulin, oligofructose and b-glucan.
  • Seaweeds: Seaweed has minerals and polysaccharides that can improve fish growth and immune system performance.
  • Mushrooms: Mushrooms have polysaccharides that promote weight gain and bolster immune systems in numerous fish species.

Customer stories

"We have been farming eel now for around 30 years. The most important thing is that the feed is of a very high quality, and that fish have a good feed intake and high performance. The Alltech Coppens feed stands out because it's really [consistent in] quality."

- Johan Meulendijks, Owner, Rijpelaal Farm, The Netherlands

"Eight years ago, we started using Aquate in [our fish] feed. We [made this change] because we know that fish need to have the right ingredients and gut health to get the right feed conversion rate, the right growth, the right health and the right skin."

- Jan Ivar Bildøy, Production Manager, Blom Trout Farm, Norway

"When it comes to tilapia, we haven’t seen anything like this. We’ve tried other live tilapia and nothing compares to what Alltech provides for us. The quality of the Alltech tilapia coming in is excellent — nice, clean fish. People love the size, they love the color, and they look very healthy. [The Alltech] tilapia is definitely our biggest seller."

- CJ Forrester, Seafood Manager, Jungle Jim's International Market, Ohio

"Using the Aquate treatment and a number of others in a controlled experiment, we were able to show that there were significantly fewer lice at all stages of development on the Aquate-fed fish. Being able to strengthen the innate immune system is a key factor in [shortening] the production cycle, [increasing] your numbers [and decreasing] your losses."

- Dr. Karin Pittman, Professor, Dept. of Biological Sciences, University of Bergen
