An 8-week feeding experiment was conducted to evaluate three types of squid Sepia esculenta liver powder (SLP) as a dietary protein source for replacement of fish meal (FM) in the juvenile black rockfish, Sebastes schlegeli. For replacement of FM, six experimental diets were formulated with 5 or 10% of either of three types (A, B, C) of SLP: SLP-A5, SLP-A10, SLP-B5, SLP-B10, SLPC 5, and SLP-C10. One of the control diets contained 100% FM as the protein source, and the other was a commercial diet (Com). Fish with an average body weight of 6.50±0.03 g (mean±SD) were allocated randomly in triplicate groups of 50 to aquaria and fed the experimental diets until satiation. The weight gain (WG) and specific growth rate (SGR) of fish fed the FM, SLP-A5, SLPA 10, and SLP-B5 diets were higher than those of fish fed the Com, SLP-B10, SLP-C5 and SLP-C10 diets. No significant differences were observed in WG and SGR among the diet groups, with the exception of the SLP-C10 diet group. The feed efficiency (FE)and protein efficiency ratio (PER) of fish fed the SLP-A5, SLP-A10, and SLP-B5 diets did not differ from those fed the control diet. However, fish fed SLP-B10 and SLP-C10 had lower FE and PER than the fish fed the FM, commercial, SLP-A5, SLP-A10, and SLPB 5 diets. Both the SLP-A and SLP-B diets, but not the SLP-C diets, replaced up to 10% and 5% of FM for juvenile black rockfish,respectively. The results of this experiment provide information that will assist in formulating an inexpensive and practical diet containing SLP for juvenile black rockfish.
