Abstract: Culture of molluscan is clearly limited by the availability of seed, as this production proceeds almost exclusively from natural recruitment. Artificial spawning and larval rearing programs could provide an alternative source of spat. This study was designed to evaluate the effect of different conditioning temperature and salinity on the broodstock maturation and Condition Factor of mangrove clam (
P. erosa) collected from different locations of Ratnagiri coast. Batches of clams from different sites were collected in February, and conditioned at temperature 26 °C, 28 °C, 30 °C and 32 °C. For conditioning at different salinity, it was kept at 10,15,20,25,30 and 35 psu, The results showed that the oocyte maturation was faster at salinity 35 psu and the best conditioning temperature was 32 °C. The Condition Factor (CF) was higher at 32 °C temperature and at 30 psu salinity, whereas, no significant difference was observed in CF at 30 and 35 psu. These results suggest that the efficient conditioning temperature and salinity is related to the natural spawning season.
