Abstract

Studies on growth and survival of the green mussel Perna viridis under suspended conditions were carried out at Kovalam near Chennai. Mussel of 2.2 cm (1.03 g) average size transplanted on ropes suspended from a raft attained 5.8 cm (14.9 g) in 3.5 months during July-October period. Using an initial density of 1.4 * 0.5 kg/m, a yield of 7.5 f 1.3 kg/m/kg of young mussels transplanted was obtained. The survival was 52 f 9% (in numbers). Results can be improved by further standardization of the initial density and size of young ones for transplantation.
