A feeding experiment was conducted to test the attractant potential of a processed protein concentrate of the blue mussel (BMPC) as replacer for fish meal (FM) protein in rapeseed protein concentrate (RPC)-based diets for turbot. Triplicate fish groups received isonitrogenous and isoenergetic diets with a 50% or 75% replacement of FM protein by a RPC (RPC 50, RPC 75), and further FM protein substitution with 0, 2, 4 or 8% of BMPC. The application of RPC 50/0 provided no significant impact on fish performance compared to FM-reference diet, while daily feed intake (DFI), specific growth rate (SGR) and feed conversion were significantly impaired when fish fed with RPC 75/0 (P<0.05). Incorporation of BMPC failed to significantly improve DFI, SGR and FCR in RPC 50 and RPC 75 treatments (P>0.05). Protein efficiency ratio and protein productive values remained unaffected among all trea.. View More»
