Abstract

The time series of estimated landings of major exploited coastal marine fish resources in different areas of exploitation along the Indian coast from 1961-2004 were subjected to trend analysis and segments of the time series were matched to a Generalised Fishery Development Model (GFDM) to indicate the historical and present status of fishery progress. Fifty-one resource-region combinations, termed as 'resources', were used for analysis. These 'resources' were grouped according to the shapes of their landings trends that conform to the different phases of the GFDM. Nearly 90% of the 'resources' were either in mature or senescent stage of development and their landings were found to have reached asymptotic level or have declined.
