To keep pace with growing demand, wild fisheries are subject to high pressure. An increasing trend in the percentage of overexploited, depleted and recovering stocks is observed since the mid-1970s. In contrast, the aquaculture sector has been the fastest growing food industry since 1970. It has become a substantial source...
Bluefin tuna capture today is focused on large fish caught by longline and smaller fish caught by purse seine for on-growing for between 3 months and 3 years. There has recently been the emergence of full life cycle farming in Japan with South Korea (Pacific bluefin tuna) and Australia (southern...
To keep pace with growing demand, wild fisheries are subject to high pressure
since the mid-1970s. Meantime, aquaculture has been the fastest growing food
industry since 1970. It has become a substantial source of food and is
increasingly viewed as a solution to the lack of production of capture
fisheries....
Considering the operational needs on fisheries management, this research was aimed for understanding the adjustment processes of small-scaled fishing gear dynamic by measuring and analysing the seasonal fishing gear dynamic including seasonal fishing pattern and fishing gear interaction. To understand the fishermen's adaptation of their fishing effort from any changes...
The impressive growth of world aquaculture has led to profound transformations in the economic structure of several capture fisheries. Evidence from the Alaska salmon fisheries supports this argument as a connection has been suggested between the recent trends of declining ex-vessel prices and the rapid development of salmon farming elsewhere...
Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish
population-dynamics and production, coupled with an aquaculture production model, to investigate
effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying
capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....
