    Keywords : aquaculture; rainbow trout; Baltic blue mussel; black solider fly larvae; digestibility; protein; fishmeal replacement;

    Abstract : A feeding trial was conducted for 9 weeks to test the growth performance, nutrient retention and digestibility in rainbow trout (Oncorhynchus mykiss) in order to assess the potential of Baltic blue mussel meal (Mytilus edulis L) and black solider fly larvae (Hermetia illucens) meal as protein sources. The dietary treatments consisted of one control diet based on high quality fishmeal, one control diet based on pea protein concentrate for testing dietary palatability and two fishmeal-free experimental diets where approximately 20% of the crude protein from the fishmeal was replaced with the protein from either de-shelled blue mussel meal or larvae meal on a dry matter basis.
