摘要

The aim of the study is to investigate the efficacy of gut probiotics in shrimp aquaculture system for the prevention of white gut (WG) and white feces (WF) disease in Litopenaeus vannamei . The study was executed in infected L. vannamei culture ponds in Varadarajapuram and Cheyyeru Gunnepalli in West and East Godavari districts of Andhra Pradesh. The rate of incidence of white gut and white feces infections in affected shrimp ponds were found to be at 21% in 57~67 days (11.11 gm) and 17% in 108~117 days (28.57 gm) of culture period, respectively. Further, the water quality parameters like temperature ((28.3±0.8)oC to (30.4±1.2)oC), salinity ((7.4±1.0) psu to (9.2±1.1) psu), dissolved oxygen ((3.3±0.5) mg/L to (5.6±0.6) mg/L), pH ((7.4±0.2) to (8.6±0.2)), and total alkalinity ((150.2±1.5) ppm to (196±1.5) ppm) were analyzed. In addition, the concentration of ammonia and nitrite in the infected shrimp pond was monitored. The simple linear regression pattern was constructed as the dependent variables between ammonia and nitrite, expressed an R 2 value of 0.952 1 (before probiotics treatment) and 0.939 4 (after probiotics treatment). Extended use of probiotics, the level of ammonia and nitrite concentration was extremely reduced in the culture pond from 0.73±0.01 to 0.038 and 0.51±0.01 to 0.001 respectively. From this study, it was concluded that the use of gut probiotic has significant impact on the retrieval of white gut and white feces disease in the L. vannamei aquaculture practice.
