Abstract
The present study assessed the growth and fish performance of juvenile red sea bream fed four isonitrogenous (46–48%) and isolipidic (15%) diets containing 45% fishmeal (control) and 15%, 30%, and 45% defatted black soldier fly (BSF) Hermetia illucens meal for 67 days. Subsequent analyses showed that there were no significant differences in the growth parameters, nutrient digestibility, and body composition of fish among all treatments. Although no significant difference was observed in fish growth, low growth was observed when the fish meal was totally replaced with the BSF meal. Higher alpha diversity of intestinal microbiota was observed in fish fed the BSF meal-based diet compared to that of the control. In the treatment groups fed the BSF meal, elevations in the presence of microbial genera that produce digestive enzymes, such as chitinase (Nocardia, Vibrio, Paenibacillus, Photobacterium), lipase (Paenibacillus, Photobacterium), and trypsin-like serine protease (Bacillus, Paenibacillus) and vitamin B group [biotin (Vibrio, Paenibacillus, Bacillus), cobalamin (Pseudomonas, Bacillus, Propionibacterium), and pyridoxin (Photobacterium)], were observed. We also found an increasing trend of bacteria producing antioxidative enzymes, such as superoxide dismutase and catalase (Nocardia, Pseudomonas, Photobacterium) in the BSF groups. These results suggested that the BSF meal could replace 67% of fishmeal without causing a negative impact on growth and lead to beneficial effects on the intestinal microbiota of the red sea bream.
期刊介绍:
Fisheries Science is the official journal of the Japanese Society of Fisheries Science, which was established in 1932. Recognized as a leading journal in its field, Fisheries Science is respected internationally for the publication of basic and applied research articles in a broad range of subject areas relevant to fisheries science. All articles are peer-reviewed by at least two experts in the field of the submitted paper. Published six times per year, Fisheries Science includes about 120 articles per volume. It has a rich history of publishing quality papers in fisheries, biology, aquaculture, environment, chemistry and biochemistry, food science and technology, and Social Science.
