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...

The sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...

At first, a paper which explores "wellbeing" in fisheries might seem misplaced. Our attention is more often focused on the poverty with which fisheries are so inherently associated and the threat of growing poverty as fishers, worldwide, face depleted fish stocks and a rapidly changing coastal environment. As this panel,...
Great efforts have been made in order to manage the fisheries more sustainably, but so far, most of these efforts have failed. This is putting the welfare of current and future generations at risk. The fishing fleets have catching capacity that well exceeds the rate at which ecosystems can produce...

Many fisheriues in Vietnam have witnessed notable reductions in catch and fish size. Given the millions of Vietnamese who are dependent on marine resources, it is critical to not only develop more sustainable
fisheries management practices, but also understand the links between vulnerability and other socio-economic and institutional factors, in...
