Microbial community structure and physicochemical factors in the water of upland pond of Litopenaeus vannamei during the middle and late stage of culture
For the culture mode of over-winter sheds( OWS),water samples were collected from Litopenaeus vannamei culture ponds aiming to investigate the variation of microbial community structure,dominant bacterial species and environmental factors in the pond water in the middle and late stage of culture. The results showed that the water temperature increased from 20.6 ℃ to26.5 ℃ after building OWS,which was suitable for the growth of shrimp. The amount of heterotrophic bacteria in the water was between 5. 1 × 104 ...
