The Effect of Schizochytrium sp. on Growth, Fatty Acid Profile and Gut Microbiota of Silver Pomfret (Pampus argenteus)

Schizochytrium sp. is a kind of heterotrophic protist, rich in docosahexaenoic acid (DHA). To study the application value fish diet, 20-day feeding experiment was initiated to evaluate its effect on growth, fatty contents, and gut microbiota important economic fish, silver pomfret. In this study, diets treatment group were added with 2% The gained more weight had higher growth rate than control group. levels DHA, eicosapentaenoic acid, polyunsaturated acids edible tissue highly increased after 20 days. After sp., high-throughput 16S rRNA sequencing showed that Proteobacteria, Firmicutes Bacteroidetes phyla highest abundance, at genus species level, we observed an abundance probiotics. results indicated ingestion could change dominant population, which might lead accelerated improved unsaturated content health. This provides reference for supplementation aid industrialization
