Abstract

India ranks third in global fish production with 6.4 million metric t, but mariculture in the Indian seas is yet to be popularised. The limited availability of protected sites and the probable conflicts with other activities such as fishing, tourism and navigation are factors likely to influence mariculture development in India, besides finance, technology, expertise and government policy. A pilot scale inshore marine cage culture experiment has been undertaken since 2007 at Visakhapatnam coast of India in the Bay of Bengal. A similar cage was launched at Munambam for the culture of Asian seabass Lates calcarifer. Asian seabass seed (3.5 ±1.5 g) reared in hapa installed in ponds for a period of 30 days were stocked in the cage and cultured for a period of 120 days and harvested at an average weight of 315.5 g. Analysis of nutrient levels in seawater near the cage, revealed no noticeable accumulation of solid particulate wastes indicating that water current (0.5 to 1.0 m sec-1) was adequate in the site to prevent accumulation of wastes in the cage as well as in the premises. The cage culture activity was found to influence the planktonic and benthic fauna.
