| 内容記述 | Fishmeal is a major ingredient for aquaculture feeds. Japanese fish feed manufacturers still heavily depend on imported fishmeal, and include fishmeal into fish feeds at approximately 40 % in 2023. Recent price increase in the imported fishmeal makes large impact on the aquaculture practice in Japan, so that the use of alternative protein ingredients has become a crucial interest. Meal of black soldier fly (BSF) larvae is a promising candidate for a fishmeal substitute in aquaculture feeds. Recently, several private companies in Japan have started to produce BSF larvae with food residues. However, a high inclusion of BSF meal (BSFm) in fish feeds has sometimes resulted in growth retardation in several fish species. Thus, in this study, a 42-day feeding experiment was conducted in juvenile red seabream (Pagrus major) using diets with various inclusion levels of BSFm. Three isoenergetic diets were prepared with fishmeal to BSFm ratios of 100:0 (Group 1), 50:50 (Group 2), and 22:78 (Group 3). Then, we investigated the protein assimilation from BSFm to fish using conventional growth analysis, stable isotope analysis and metabolomic analysis. Group 1 exhibited a significantly higher specific growth rate (2.92 ± 0.22 %/day) than Group 3 (2.54 ± 0.22 %/day), while Group 2 (2.77 ± 0.21 %/day) did not show a significant difference relative to Group 1. Stable isotope analysis suggested a lower assimilation of BSF protein in Groups 2 and 3, as indicated by their δN15 ratios. In vitro digestion evaluation suggested that several essential amino acids (EAAs) in the diet for Group 3 were potentially deficient compared to the diet for Group 1. These results suggest that a diet comprising up to 50 % BSFm does not negatively affect the growth of red seabream, but an EAA deficiency may have retarded the growth in Group 3. Therefore, further nutritional improvement is needed for diet with BSFm inclusion level above 50 %. | |||||||||||||||||||||||||||||
