We evaluated the dietary fish meal analogue as a fish meal replacer based on growth, hematology, non-specific immune responses and intestinal integrity in growing Japanese eel, Anguilla japonica. Five experimental diets contained the animal protein sources as 100% FM (FMA(0)) as control, 90% FM + 10% FMA (FMA(10)), 80% FM + 20% FMA (FMA(20)), 70% FM + 30% FMA (FMA(30)) and 60% FM + 40% FMA (FMA(40)). Each group of 13 fish with an average initial body weight of 119.60 +/- 0.97 g (mean +/- SD) were randomly distributed into 15 tanks (250-L each) in triplicates and fish were fed twice a day with one of the 5 experimental diets for 10 weeks. At the end of the feeding trial, weight gain (WG), specific growth rate (SGR), feed intake (FI) and feed efficiency (FE) of fish fed the FMA(0), FMA(10), and FMA(20) diets were significantly higher than those of fish fed the FMA(30) and FMA(40) diets. Whole body proximate composition and amino acids profile of fish were not affected by dietary treatments. Broken-line regression analysis indicates the optimum dietary FMA replacement level could be 15.39%. Hemato-biochemical parameters such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), and triglycerides (TG) were higher in fish fed the FMA(30) and FMA(40) diets than those of fish fed the FMA(0), FMA(10), and FMA(20) diets. Non-specific immune responses in terms of serum superoxide dismutase (SOD) and lysozyme activities were unaffected among fish fed the diets. Distal intestinal histology of fish fed the FMA(30) and FMA(40) diets showed abnormal villi structural arrangements (fold breaks, dilation, and dwarf villi) compared to those of fish fed the FMA(0), FMA(10), and FMA(20) diets. Therefore, the results indicated that the optimum level of dietary FMA could fall between 15.39% and 20% in growing Japanese eel.
