Black clam (Villorita cyprinoides), constitute a major molluscan based subsistence level fishery in Vembanadlake providing a variety of ecosystem services to the dependent populations of the ecosystem. The non-realization of the values of the services provided by clams coupled with the anthropogenic activities like dredging aggravated the non-sustainable harvest of the resource. The paper attempts to evaluate the provisioning and cultural services provided by clams in-order to highlight the importance of the management of this ecosystem service provider and various tradeoffs between anthropogenic activities and clam resource utilizations
