The effect of “Fishery-PV Integration” on Penaeus monodon culture and research on the micro-ecological environment

“Fishery-photovoltaic (PV) Integration” is a novel aquaculture model that provides enormous potential for development. However, research on the environment and organisms under “Fishery-PV mode presently sparse. This study investigated Penaeus monodon as model, studying growth rates of shrimp, water quality conditions, micro-ecological environment. After 105 days rearing, P. (initial weight 0.006 ± 0.001 g) reached an average body 11.69 0.92 g. The was stable (C( NH4+ ) ≤ 1.57 mg/L) during experimental period. 16S rRNA gene sequencing results showed bacterial community structures were significantly distinct among water, effluent intestinal environments, with closer relationship between microbiotas in water. dominant phyla present shrimp intestines, Proteobacteria, Actinobacteriota, Bacteroidota. Likewise, Ralstonia , Candidatus Aquiluna Vibrio genus three groups. relative abundance common opportunistic pathogen relatively low, which beneficial to promote healthy shrimp. function microbiota using metagenomic technology.
