To determine if diet affects the growth rate of juvenile ling cod, we began with three initial objectives: 1) Record the growth rates of juvenile lingcod on different diets (squid and sardine); 2) Determine if hemocyanin will cause lingcod skin and muscle pigmentation will take on a...
Norwegian aquaculture emerged in the end of 1960 when new discoveries transformed production from trout farming to salmon farming. During recent decades farmed salmon has been one of the most successful aquaculture species in terms of production growth. Annual global production has increased from a few thousand tons in 1980...
Today fish is the most traded food commodity in the World. This situation is not without generating potential issues. On the one hand, fish trade is said to support economic growth processes in developing
countries by providing an important source of cash revenue. On the other hand, fish trade is...
This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that...
Khanh Hoa, featured by advantageous conditions from both nature and humans, has long enjoyed great potentials for fisheries development. The most immediate evidence can be cited is that the fisheries industry
made significant contributions to the local economic growth during the recent period of 2001- 2006, and impressive figures in...
Capture fisheries is a primary employment for inhabitants of coastal and inland aquatic ecosystems globally. However, historically, aquaculture has been well documented as an economic activity in Southeast Asia. Coastal marine fisheries and freshwater inland waters provided employment for inhabitants of these ecosystems in Sub-Saharan Africa (SSA). Aquaculture was started...
This paper explores the possibility of using marine reserves to protect stocks subject to bycatch problems. The importance of migration rates and growth rates of both target and bycatch species and costs are analyzed. Pure open access equilibrium harvest of target species and stock level of bycatch species are compared...
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....
