Total and partial fishmeal substitution by poultry by-product meal (petfood grade) and enrichment with acid fish silage in aquafeeds for juveniles of rainbow trout Oncorhynchus mykiss
Aquafeeds are formulated with a high content of fishmeal as protein source. The fishmeal is usually produced from pelagic fish resulting in a reduction of fish availability for human consumption. Thus, it is important to find appropriate protein substitutes in the production of formulated aquafeeds....
