Abstract

The green mussel Perna viridis is an edible moilusc with enormous culture potential. This paper presents data on the reproduction, spat settlement and growth rate of P, viridis in Edaiyur backwaters on the east coast of India. The mussels exhibit two spawning periods and temperature appears to regulate the onset of reproductive events. Spat settlement densities are greater in the adjacent coastal waters as compared to the backwaters. Growth rate data show that the mussels reach an average shell length of 83 mm in 1 year. The results also show that shelland meat weight exhibit different seasonal patterns of growth in Edaiyur backwaters. In rope culture, marketable size (50-60 mm shell length) was achieved in about 6 months with an annual production of 47 kg m(-1) and biomass (wet meat weight) of 22 kg m(-1). The annual production values in Edaiyur backwaters are relatively higher than those reported from other parts of India. The present study suggests that Edaiyurbackwaters represent a potential site for successful cultivation of P, viridis considering the availability of sustainable wild stocks of P, viridis and abundance of seed along with favourable environmental conditions.
