Clam resources of the Ashtamudi lake, with special reference to Katelysia opima (Gmelin) fishery

Abstract

The clam fishery rasourcts of ths Ashtamudi lake are supported by several species belonging to Vlllorlta, Katelysia, Meretrix and Paphia. However, Villorlta cyprlnoides and Katelysia opima contribute to the bulk of the resource. The extant of the major clam beds, the estimate of the present stock and the magnitude of the existing fishery suggest increased production. The exploitation and utilization of Katelysia, which has got great export potential, are dealt with in detail. Some steps for the judicious management of the clam resources are also suggested.
