- Abstract
- This study identified the current status of fisheries management of shrimp trawling in Arafura Sea. Recent management measures are taken to utilize and maintain the fisheries resources in an optimal manner. Those include 2 main approaches which are input control focused on license system and application of technical measures. Main structure of this management is establishing community-based fisheries management.
However, fisheries management of shrimp trawling has not been much effective so that excessive fishing effort is occurred and it results on overfishing. This study identifies ineffectiveness of the fisheries management of shrimp trawling in Arafura Sea and emphasize on the effective solution of the overfishing.
Approaches to the solution are using bio-economic analysis to develop alternative measures of effective fisheries management focus on using BRD of shrimp trawling or reducing fishing effort.
To estimate Maximum Sustainable Yield (MSY) and fishing effort in MSY level (EMSY), this study uses surplus production models which is namely (1) Schaefer (1957) model, (2) Schnute (1977) model and (3) Walters and Hilborn (1976) model and two exponential growth models, (4) Fox (1970) model, and (5) Clark, Yoshimoto and Pooley (1992) model.
Based on the bioeconomic result, through collecting the problems of ineffective fisheries management of shrimp trawling and many kind of policy analysis, this study suggests some alternative measures for effective fisheries management of shrimp trawling. Those alternative measures are (1) limiting fishing effort to the MSY level by relocating some trawl vessel to new trawlable area, (2) controlling license issuance and establishing closure area and closure season, (3) using environmentally friendly trawl net which optimally reduce by-catch species and maintain shrimp catch (4) establishing clear fishing zone boundary by using longitude and latitude as a definite lines and (5) strengthening regulation enforcement through co-management system and monitoring, controlling and surveillance (MCS) system.
