Novel Meals from Eastern Canada’s Marine Fishery By-products as Alternatives to Fishmeal

ABSTRACT

There is a current trend in the aquaculture industry to find “eco-friendly” alternatives to fishmeal that will provide fish with all the needed essential nutrients. Our objective was to identify, produce, and chemically characterize nine novel meals composed of underutilized marine fishery by-products from eastern Canada. Snow crab hepatopancreas was found to be a good supplement of monounsaturated fatty acids, iron, copper, and zinc. Herring immature ovaries and shrimp mince could be a partial replacement for fishmeal as revealed by their essential amino acid profile and polyunsaturated fatty acids. Finally, herring testis was very rich in high arginine and taurine.
