Abstract

Pelteobagrus fulvidraco integrated multi-trophic aquaculture system (YPS) is a new ecological culture system of Pelteobagrus fulvidraco. In this manuscript, we used high throughput sequencing technology and the water analysis method to analyze the bacterial community characteristics of YPS and the water environment, respectively. The results showed that the concentration of total nitrogen (1.47~1.84 mg/L) and total phosphorus (0.14~0.18 mg/L) reached the discharge standard of freshwater pond aquaculture water, and the concentrations of ammonia (0.10~0.95 mg/L) and nitrite (3.85~6.68 μg/L) were lower than those in traditional ponds, which was suitable for the growth of Pelteobagrus fulvidraco. At the phylum level, Actinobacteria (35.68%), Firmicutes (24.58%), Proteobacteria (23.49%) and Bacteroidetes (6.59%) were the dominant phyla. The abundance of genus had obvious seasonal variation characteristics. In spring (April), Limnohabitans (8.01%) was the dominant genus; in early summer (June), Exiguobacterium (23.44%), Planococcus (22.27%), Paenisporosarcina (16.81%) and Planomicrobium (5.85%) were the dominant genera; at the end of summer (August), hgcI_clade (21.84%) and CL500_29_marin_group (4.61%) were the dominant genera; compared with the end of summer, the dominant genera Sporichthyaceae (11.31%) and Sediminibacterium (3.32%) were newly added in autumn (October). The dominant genera in different periods were correlated with dissolved oxygen, water temperature and nitrogen nutrients. With the accumulation of nitrogen nutrients in water, the abundance of metabolic pathways in the bacterial community increased, and the abundance of infectious and immune disease pathways increased. This study provides a theoretical basis for the regulation of YPS.
