The growth, mortality and exploitation status of Otolithoides pama collected from the Hooghly-Matlah
estuarine system of West Bengal, India from November 2016 to April 2018 were estimated. The
sample specimens were collected from the artisanal fishery, mainly from drift gillnets and bagnet
with mesh size 15–70 mm and the length-frequency distribution was analyzed employing the FiSAT
programme. The growth parameters Lα, K and t0 were estimated at 418 mm, 0.58 yr−1 and -0.1356
years, respectively. The lengths of the fish at the end of 1st, 2nd, 3rd, 4th and 5th year were recorded as
202, 297, 350, 380 and 397 mm, respectively. The total mortality (Z), natural mortality (M) and fishing
mortality (F) were 4.16, 1.14 and 3.02 yr−1, respectively. The exploitation level (E) was observed as
0.73 which surpassed the optimization value of 0.5 considered for sustainable fisheries. The present
study revealed that the fishery is overexploited and calls for an urgent need to reduce the fishing
pressure to accomplish a sustainable fishery.
