The hatchery technology for mud crab is a much in demand species in South East Asian countries where live crabs are highly preferred as a delectable seafood 

  MPEDA-RGCA’’s mud crab hatchery technology, has been granted patent by the Controller General of Patent, Design and Trade Marks, Government of India, for 20 years from 2011 to 2030.The hatchery technology for mud crab (scientific name Scylla serrata), a much in demand species in South East Asian countries where live crabs are highly preferred as a delectable seafood, has been developed by the Rajiv Gandhi Centre for Aquaculture (RGCA), the research and development arm of the Marine Products Export Development Authority (MPEDA).

 MPEDA Chairman K S Srinivas said it is a remarkable achievement in the history of Indian aquaculture as for the first time the central government has granted a patent for this technology in the country.

“It will go a long way in meeting the seed requirement of farmers who intend to undertake diversified species for aquaculture instead of concentrating on shrimp farming alone. MPEDA is dedicating this achievement to the aquaculture farmers of the country for their support and to the young scientists of RGCA who have worked tirelessly to achieve this morale-boosting feat,” Srinivas, president of RGCA, said in a statement.

Taking into account that there is no other hatchery for mud crab in India, RGCA had applied for patent right for the mud crab hatchery technology in 2011 with the Controller General of Patent, Design and Trade Marks. However, the patent was granted after following a long and arduous process.

Keeping in view the huge demand of mud crab, especially in South East Asian countries, MPEDA had initiated a pilot project for mud crab seed (known as crab-instar) production during 2004 and subsequently made the commercial hatchery for the first time in India during 2013 with the capacity of one million per annum.

The MPEDA chairman said the major achievement lies in increasing the survival rate of crab instar from three per cent world record to seven per cent. Further, the hatchery unit is designed in such a manner that all sections are under one roof with complete bio-security measures. So far, 7.28 million seeds have been produced and supplied to 659 farmers across the country.

RGCA has been set up to give a fillip to commercialisation of diversified aquaculture species such as sea bass, mud crab, Genetically Improved Farmed Tilapia (GIFT), cobia, pompano and artemia.
