Abstract/Description: | Observations made during January 1977 to June 1978 indicated the existence of rich clam beds in the Vellar Estuary. Clams were distributed from river mouth to 10 km. towards the upper reaches of the estuary. Total stock of clams varied in different months from 354 t to 7050 t of which 88.0% to 99.8% was formed by Meretrix casta and the rest by Katelysia opima. Density of clams per square metre was observed to be always higher in the upper reaches (210 g to 5920 g) than in mid (9.4 g to 2290 g) and lower (1 g to 864 g) reaches of the estuary. M. casta was dominant in all the zones; however K. opima was more in latter. Length composition of these clams in different months indicated that spat fall occurred during March-September with peak in April-July. Fishing was done by agricultural labourers in their off season. The method of collection was by hand picking and scooping with bamboo baskets during low tide. 1045 m tons of clams was landed during the period of observation. 70% of this landings was directly utilised for lime industry and the rest for shucking meat. Problems of the clam fishery at Vellar and the scope of expansion of the fishery are discussed. |
