Rising temperature causes 60% mortality in shrimp farms

24 May 2011 Evaluate

The summer heat is causing 50%-60% of mortality in shrimp farms across the country. Though farm owners are worried about the crop loss due to high mortality but they expect that the year-end production may not see a major drop.

In February-March, farmers begin the first crop -- with a 120-day maturity cycle -- of the year and by June the crop becomes ready to be harvested. Especially in Orissa, Bengal and parts of Andhra Pradesh the crop loss in open ponds is high due to the rising temperature this year. In 2010-11, the production of farmed shrimp rose by 30% at 1.45 lakh tone. Bulk of the shrimp exported out of the country comes from aquaculture farms.

The national committee member of the Seafood Exporters Association of India feels year end production may not see a major dip as farmers go for distress harvest to minimize losses and another round of crop is usually taken soon after cleaning the pond.
