Potential of Sustainable Fishery Resources at Giam Siak Kecil-Bukit Batu Biosphere Reserve, Riau Province, Indonesia

Abstract

Fisheries are fundamental part of human activities. Sustainable fishing is an important aspect in maintining the fishery resources for the future generation. The main objective of this study is to estimate the maximum sustainable yield (MSY) of the fishing grounds for the sustainable harvesting. This study deploy the approximate estimation of abundance (biomass) and potential estimation of a type or group of fish species based on the analysis of production surplus to determine the sustainability of maximum catch rate. Results of the research identified about 35 species from the 17 families of fish. Based on the MSY calculation using the Schaefer method with a long line standard, the fish utilization status is in overfishing condition status at all sampling points, with the value above 98% above the standard capture limit of 70%. The results of the Schaefer model provide the baseline information on MYS for the freshwaters fish, which could be used as the basis for future fishery assessment and management of this biosphere reserve.
