Abstract

he study was conducted to determine the catch composition of indigenous winter migratory coastal set bagnet (CSBN) operating in Hooghly-Matlah Estuary. Experiments were carried out for a period of four months during the winter migratory fishing season from mid-November 2016 to mid-February 2017. A total of fortyeight (48) hauls was made in twelve (12) days of fishing trials. Two complete days were expended with an average of four trials in every fortnight sampling during both flood current and ebb current. The soaking period was fixed to six (6) hours for each trial including the time of setting and hauling. A total of 20 commercially important finfishes such as Harpadon nehereus, Setipinna phasa, Setipinna taty, Coilia dussumieri, Coilia ramcarti, Otolithoides pama, Polynemus paradiseus, Daysciaena albida, Johnius dussumieri, Arius arius, Arius maculates, Arius jella, Mystus tengara, Ilisha megaloptera, Silaginopsis panijus,, Trichiurus lepturus, Osteogeneiosus militaris, Lepturocanthus savala, Chirocentrus dorab, Pampus argenteus. Shellfishes like Metapenaeus monoceros, Metapenaeus dobsoni, Penaeus indicus, Penaeus monodon, Macrobrachium lamarrei and Macrobrachim mirable were also recorded in the winter migratory coastal set bagnet. 16.72% of the total catch were contributed by Bombay duck, which was the dominant fishery followed by ribbon fishes and total shell fish contribution was 17.81% of the total catch
