Fish and shrimp diets used to contain a large proportion of fish meal, but due to costs, the fish meal is often replaced by vegetable proteins. More companies are getting involved in supplying ingredients for the aqua feed industry. In fish farm...

Raw materials of marine origin are still widely employed in fish feeds. One of the major challenges in fish nutrition is to ensure their successful replacement.

The composition of plant raw materials differs in particular from that of marine raw materials in terms of amino acids and fatty acids.

With respect to proteins, plant raw materials do not provide the same quantity of essential amino acids (EAA) as fish meal, and this replacement must be accompanied by supplementation of the diet in synthetic EAA.

Fish feed is a major expense for many aquaculture operations. New research by Agricultural Research Service (ARS) scientists shows that ethanol co-products, such as Dried Distillers Grains with Solubles (DDGS) can provide protein for fish feeds ...

Today's expectations are that the fish feed supplier can produce a product that hits precise quality targets in terms of size, durability, density and nutritional composition at a highly competitive price. Proper fish feed processing is therefor...

Because fish feeds usually contain relatively high amounts of fish meal and/or fish oil, they are very susceptible to rancidity. In addition, ascorbic acid is highly volatile, but critical to normal growth and development of most species of fish...
