Evaluation of fish meal analogue as partial fish meal replacement in the diet of growing Japanese eel Anguilla japonica

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…
