In the present study the effectiveness of polymerase chain reaction (PCR) screened fry for controlling white spot disease in semi-intensive culture of penaeid shrimp, Penaeus monodon was evaluated. PCR tested negative post-larvae and without PCR screened post-larvae were stocked for culture for 135 days in treatment ponds and control ponds respectively at a stocking density of 15 m-2 under similar management protocols. PCR surveillance resulted negative in initial, intermediate and pre-harvest culture phases in treatment ponds. However, emergency harvest occurred prematurely in 66.6% of control ponds with symptoms of white spot disease. Harvest outcome showed significantly higher (p<0.05) average body weight and yield resulting in higher net profit, benefit cost ratio and return on investment in treatment ponds than the control. Thus, the study reveals that stocking of PCR negative fry become an effective biosecurity tool and increased production of penaeid shrimp in growout ponds of West Bengal, India.Pages: 113-118 | 825 Views 5 DownloadsDownload Full Article:
