Abstract

Sustainable marine fisheries resource harvest and management depend heavily on the sound scientific investigation of the stock status of the resources on a periodic basis. In the Indian context, given the sheer diversity of fishery resources tapped with numerous craft gear combinations, the task of evaluating the individual management units (or stock) is intrinsically challenging. The complexity increases manifold when several similar looking species of a fishery group are landed together, posing difficulties in enumerating species wise abundance data from the field observations. Croakers with a high α-diversity and overlapping distribution form a significant component of the high value marine fish landings in India. Around a dozen species on the north-west coast of India are contributing significantly to the commercial landings. Since these individual species vary considerably in their life history traits, abundances and distribution pattern, species specific assessment of the resource status is desirable. The trawl fishery of the region has experienced significant ‘technology creep’ in terms of gear modification as well as species targeted, especially during the last one and half decade. Hence, the species-specific information gaps needed to be identified and addressed scientifically with advisories for sustainable management of croaker fishery.
