In the Barents Sea, recruitment of North-East Arctic cod is affected by sea temperature, being higher in warm years. Cod dynamics are furthermore influenced by time-lagged competition for capelin with herring, and the intensity of size-selected harvesting. The system is not stable in three ways: (1) the effect of temperature...
There is an increasing realisation that the earth’s marine environment is being adversely impacted by the
production of carbon dioxide in the earth’s atmosphere. Climate change in the oceans and atmosphere will
impact fisheries production and management and have implications for governance of fish stocks. Climate
change may have substantial...
The Coral Triangle Initative is a new initative in environmental ecosystem management which as officially kicked-off by 6 countries in December 2007. The paper reviews the history of the initiative (transboundary international "Peace parks" concept, bringing together other eco-regional initiatives) and points to the direction it is currently taking with...
In the summer of 2005, fishing began under a novel management program in the Bering Sea and Aleutian Islands crab fisheries. To protect processor and community interests, the program requires harvesters to land their catch with processors having historic participation in the fisheries. This requirement effectively prevents
processor competition for...
This paper investigates the application of cellular automata (CA) models in bioeconomic studies involving varying biological growth and area distribution. A simple 2D continuous cellular automata (CCA) model is presented and incorporated in a fish harvest model based on standard assumptions of economic rational behaviour by individual decision makers. The...
Collaborative management is essential in fisheries with multiple users, where different fishing groups compete to exploit a shared stock, often using unsustainable practices. This is the case in the Coral Triangle, an ecosystem increasingly coveted by conservation organizations for its high biodiversity, and heavily exploited by fishing groups from the...
Main objective of this paper is to analysis in what extent culture-based fisheries (CBF) facilitates increase rural income to reduce the poverty gap among the agricultural farming communities associated with village reservoirs in Sri Lanka The present study deals with the economic analysis CBF in 23 successfully harvested village reservoirs...
Molluscan shellfish culture is an important component of the commercial aquaculture industry in Florida, USA. The primary species cultured is the hard clam, Mercenaria mercenaria. Currently, annual grower revenues total approximately $15 million, which generate $40 million in economic impact to the state. However, hard clam production in other USA...
Five species of marine turtles are found within the territorial waters of Vietnam, and all populations are declining. As part of a broader strategy and Action Plan, the Government of Vietnam and WWF Vietnam have launched a two-year project to: 1) document relative gear impacts, and geographic hotspots , for...
