India and Israel

All-Male Freshwater Prawns


A new technology, supported by India’s Marine Products Export Development Authority (MPEDA), has the potential to triple the production of freshwater prawns (Macrobrachium rosenbergii) in India.  Developed by Professor Amir Sagi of Ben Gurion University of the Negev in Israel, the new method allows farmers to grow all-male prawns that grow three times larger than female prawns over a six-month period, without genetic modification or using chemicals or hormones.


While female prawns grow to 15 to 25 grams in six months, male prawns grow to 80 to 130 grams during the same period, said M. Shaji, deputy director of MPEDA.  In Andhra Pradesh, a state on the east coast of India, MPEDA has been running test projects in Manikonda, near Vijayawada, in collaboration with Rajiv Gandhi Centre for Aquaculture (RGCA), and the results have been quite promising.  Now MPEDA has started commercial farming using the new method at a private farm in the state of Kerala, near Muthalamada in Palakkad District.


With this new technology, a farmer could get two to three metric tons of freshwater prawns per hectare annually.  If 2,000 hectares of ponds were converted to all-male prawns and if the prawns fetched $8 per kilogram, the ponds could produce revenue of $32.5 million, Shaji said.  “India was the first country to use this technology, and now it is being used in Vietnam, China and Myanmar,” said Sagi, who is a consultant to RGCA and supervising the projects in Andhra Pradesh.
