Sustainable Management of Shrimp Trawl Fishery in Tonkin Gulf, Vietnam


Thanh Viet Nguyen


This study investigates the sustainability of shrimp stock in the trawl fishery in the Tonkin Gulf, Vietnam. It is a small scale and multi-species fishery. The Verhulst-Schaefer and Gompertz-Fox surplus production models are applied. There are two shrimp spawning seasons in a year in the Gulf. Therefore, in this study, the surplus production models, associated to catch calendar and effort data, are applied for a half-year time interval. The results indicate that the fishing effort should be reduced by roughly 12-44% to achieve the maximum sustainable yield and 46-61% to reach the maximum economic yield. With a social discount rate of 10%, the effort should decrease by around 45-56% to achieve the optimal yield. The entry tax should be 92-279 USD/month/boat to achieve the maximum sustainable yield and 160-314 USD/month/boat to attain the maximum economic yield.

Keywords:   bioeconomic analysis, shrimp trawl fishery, fishery management, Vietnam
