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...
The role of market incentives in supporting the move towards sustainable seafood production is increasingly being demonstrated in the real world although the level of documentation is relatively poor. Market demand is strongest in western Europe where the greatest effort has been made by organisations such as the MSC to...
Up to now cost measurements in the Senegalese demersal fisheries have been limited to the assessment of the financial viability of fleets or the comparison between revenues of the fleet and costs of the management. But all of these works are only concerned with the financial cost of fishing activity....
Developing country fisheries serve many functions, from feeding the poor, sustaining local communities and providing employment to generating export earnings. Yet, despite their importance, most countries have largely failed to ensure sustainable fishery systems and livelihoods for the millions of people dependent on them. Classically, management has concentrated on the...
During 1986-2006, fisheries in Tonkin Gulf had made rapid development. Total engine power increased 11.6 times while total catch only increased 2.9 times. Big increase in number of fishing boats has resulted to the overexploitation in near shore waters since 1995 and this situation has been spread out all over...
Relentless overfishing, illegal and unreported catches, environmentally damaging fishing methods and unwanted by-catches are some of the challenges to fisheries management. Community based fisheries management and co-management are believed to be effective methodologies to bring about sustainable utilization of fisheries resources. Interestingly, indigenous resource management practices among small scale fishers,...
Gujarat, a major maritime state, has 20 percent coastline and accounts for 10 per cent of fish production of India. Recently, the government of Gujarat has placed a special emphasis on the development of ports with an objective to explore the opportunities of trade through the ports. The government plans...
The Northern Prawn Fishery is one of the most valuable fisheries in Australia with a yearly estimated value of production of about $64mil. Nine prawn species are commercially harvested from the Northern Prawn Fishery with 80% of annual average catch represented by the banana prawn (Fenneropenaeus merguiensis) and the tiger...
The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated...
