Observations on environmental parameters clearly indicate two independent ecosystem at Ribandar and Banastrim clam beds in Mandovi-Cumbarjua canal-Zuari estuarine system of Goa. Maximum size attained by Meretrix casta in this estuarine system is 55 mm. Recruitment to the clam population at Banastrim is earlier and more prolonged than at Ribandar. Length-frequency studies indicate that M. casta at Banastrim breeds throughout the year, whereas at Ribandar, breeding is suspended during peak summer. Low salinity adversely affects the growth. Year-class composition at Ribandar is dominated by 1-yr class and at Banastarim by 0-yr class. Possibility of migration of adult clams at Banastrim is postulated. Dimensional relationship marks out the existence of different stocks of M. casta in this estuarine system of Goa. An overall appraisal of the results reveal the possibilities of culture of clams in the estuaries of Goa. |
