The commercial shrimp culture was introduced in late 1990s and reaching a peak in 1994 and thereafter it was suddenly declined in the Andhra Pradesh. The series of white spot disease outbreaks, lack of quality seed and feed, problems in quality brood stock, increased cost of production on account of feed, labour and the mandatory certificates requirements are suggested to be some of the important factors leading to the production decline. While majority of the output comes from Andhra Pradesh, particularly the East Godavari West Godavari, Krishna and Nellore districts.
