The efficacy of povidone iodine as a surface disinfectant was assessed in white shrimp (Litopenaeus vannamei) eggs and larvae. Eggs and nauplii were exposed to povidone iodine 20 ppm for 20 seconds. Culture-based method and Terminal Restriction Fragment Length Polymorphism (T-RFLP) were used to monitor the total number of bacteria and diversity of the bacterial community associated with shrimp eggs and larva at each developmental stage. Povidone iodine reduced the total culturable bacteria, especially Vibrio, on eggs and nauplii, as well as the total bacteria in the whole community as estimated by T-RFLP results. Povidone iodine also reduced the diversity of bacterial community and altered the evenness of phylotypes distribution suggesting that the use of povidone iodine as a surface disinfectant in shrimp aquaculture should be reconsidered.

Intestinal bacteria are crucial for the healthy aquaculture of Litopenaeus vannamei, and the coastal areas of China are important areas for concentrated L. vannamei cultivation. In this study, we evaluated different compositions and structures, key roles, and functional potentials of the intestinal bacterial community of L. vannamei shrimp collected in 12 Chinese coastal cities and investigated the correlation between the intestinal bacteria and functional potentials. The dominant bacteria in the shrimp intestines included Proteobacteria, Bacteroidetes, Tenericutes, Firmicutes, and Actinobacteria, and the main potential functions were metabolism, genetic information processing, and environmental information processing. Although the composition and structure of the intestinal bacterial community, potential pathogenic bacteria, and spoilage organisms varied from region to region, the functional potentials were homeostatic and significantly (p < 0.05) correlated with intestinal bacteria (at the family level) to different degrees. The correlation between intestinal bacteria and functional potentials further suggested that L. vannamei had sufficient functional redundancy to maintain its own health. These findings help us understand differences among the intestinal bacterial communities of L. vannamei cultivated in different regions and provide a basis for the disease management and healthy aquaculture of L. vannamei.
