Estimation of Maximum Sustainable Yield (MSY) for Sustainable Fish Catch

Abstract

Abstract Fishery is an entity engage with fish catch on the sea ground by fisherman. The fish catch in Peninsular Malaysia has declined by more than 90% since 1960s. Thus, it is important to know the maximum sustainable yield in order to overcome the decreasing number of fish and estimate the number of fishes that can be caught from the sea without endangering the fish population. The main purpose of this study is to calculate the maximum sustainable yield of fish catch in Terengganu by applying Bayesian surplus method. The results show that the amount of maximum sustainable yield is 100100 tons with 205700 fishing trips per year. Based on the value of maximum sustainable yield and optimum number of fishing trip, the current fish stocks have been overfished from year 2000 to 2008 since the fish catch and fishing effort for the year exceeded the optimum value. As a result, the numbers of fish catch for the year 2009 to 2016 was lower even though the fisherman put higher fishing effort.
