Abstract

This paper highlights the richness of information available in an expanded ICAR-CMFRI-NMFDC fish catch and effort database for the state of Kerala. Strengthening of the database by digitizing data in the old paper data sheets was done under a multi-national project, ICAR-CMFRI-CSIRO-LENFEST Ocean Programme. The high diversity of fished taxa was classified according to the periodicity of its occurrence over this long period. Guidelines for determining the number of species for which stock assessment is to be carried out in the context of a multigear and multispecies fisheries sector were derived. This national-level database will be of immense use to researchers and policy makers for preparing fisheries management plans for the sustainable harvest of marine fishery resources.
