Description 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.
