Abstract

Croakers are locally called as “Patharamundi”, “Sila” or “Borei” are commercially important demersal resources exploited all along the Odisha coast. The diversity and status of croaker fishery along Odisha coast in the Bay of Bengal is reported. Landings of croakers showed an increasing trend over the decades with lowest catch recorded in 1976 (333 tonnes) and peaked in 2011 (46,468 tonnes) after which the catch has been declining till 2018. Among the maritime states of India, Odisha, contributing 20,625 tonnes accounting for 18% of the country’s total croaker landings in 2020, showed a tremendous increase compared to the previous year. It was a significant component in the trawl catches forming 34% of the total demersal fish landings and 12% of the total marine fish landings of Odisha. Lesser sciaenids (49%) dominated the croaker landings. They were caught by various gears such as trawl nets, gillnets, hook & line, ringseines, and shoreseines. Bulk of the catches were taken by trawl nets (73%) followed by gillnets (22%). More than 20 species contribute to the fishery of which the major species were “lesser sciaenids” such as Johnius carutta (40%), Pennahia anea (30%), Panna heterolepis (12%), Kathala axillaris (9%), Nibea maculata (5%). Otolithes ruber (66%), Chrysochir aureus (23%), Pterotolithus maculatus (7%) dominated in the “intermediate sciaenids” and Otolithoides pama among the “greater sciaenids” with 98% contribution. Protonibea diacanthus locally called as “Telia” is gaining attention among the fishermen in the recent past due to their high quality swim bladders which are used for the production of isinglass for export. As compared to previous years, the lowest catch was reported in 2020 (0.30 tonnes) probably due to non-fishery causes such as Covid pandemic which affected general fishing activities.However, continuous monitoring and management of this economically important species is required. Juveniles and young adults of several species of croakers in bottom trawls as bycatch can cause an economic loss to the fishery sector and require management measures.
