AQUAFEED
The aqua culture industry is rapidly growing as a result of the growing demand for fish. In addition, over the years more knowledge has been gained how to commercially produce tropical fish in cages, which has resulted in the farming of over 200 fish species today. Also shrimp farming is growing rapidly. Read more...
Introduction

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...

DDGS in fish feed

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 ...

Fish feed storage

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...
