Research into alternative proteins in aquafeeds

The US Department of Agriculture with the University of Idaho are carrying out research into the effects of replacing fishmeal with blends of alternative proteins on growth performance of rainbow trout, and early or late stage juvenile Atlantic salmon. The purpose of the research was to evaluate different blends of proteins as possible replacement for fishmeal in diets.

Replacement of fishmeal with alternative protein blends in diets for early stage juvenile salmon is not recommended and the penalty in growth is severe. Fishmeal can be completely replaced in diets for late stage salmon over 30g without compromising fish performance or using land animal protein ingredients in feed formulations. Read more ...
