    Abstract

    Objective of the study:- -To indicate maximum sustainable yield after evaluating the sciaenid fishery and to suggest the measures for it". In this case, the yield per recruit was estimated by using the growth parameters, mortality and length/age at first capture. These parameters were estimated by studying their age and growth aspects of these two species. In that context, two species of sciaenids from Konkan coast were selected for the study. Konkan coast consists of Raigad, Ratnagiri and Sindhudurg districts of Maharashtra. This coast starts from Mora fish landing centre, the north end of Raigad district and ends at Reddi, the Southendof Sindhudurg district (Fig. I). For years together, the coast is providing rich marine resources such as mackerel, sardine, prawn, sciaenid, ribbon fish, catfish etc. This region contributed about 27% to the total marine fish production of the state during 1983-84 where contribution of Ratnagiri was 16%. In the State 29% sciaenid landings came from Ratnagiri district (CMFRI, 1987). Ratnagiri fish landing centre is the biggest fish landing centre on the Konkan coast from where 460 small fishing trawlers, (32'-45') are in operation. Considering all these points, Ratnagiri fish landing centre was selected for the study.
