Abstract:: Rising consumer concern over intensive food production issues has resulted in an increase in demand for organic alternatives to a wide variety of foods including fruit and vegetables, meat and poultry. More recently, there has also been considerable interest in the marketing of more environmentally-friendly supplies of fish, including those...

Creator:: Tveterås, Ragnar, Tveterås, Sigbjørn, and Sissener, Elin H.
Abstract:: Increased livestock and aquaculture production can put pressure on the fishmeal market, and thus industrial fisheries stocks, since both of these sectors use fishmeal in their feeds. Data indicate that fishmeal supply has reached a production limit due to limited marine resources. Meanwhile there has been an explosive growth in...

Abstract:: Fishing overcapacity has lead to unsustainable harvesting and rent dissipation in global fisheries. Only government intervention of some kind can lead to a reduction in capacity. If efficiency is the primary objective for the regulator, then the least efficient vessels should be decommissioned. Here we analyze the Swedish fishery using...

Creator:: Eggert, Hakan and Tveteras, Ragnar
Abstract:: Several factors contribute to the productivity of nations' fisheries: (1) The biophysical conditions that determine the abundance of fish stocks, (2) government regulation of fisheries, and (3) innovation and adoption of (i.e. investments in) new fishing technologies. This paper analyzes the long-run productivity performance of three Nordic countries Iceland, Norway...

Creator:: Mikkelsen, Eirik
Abstract:: 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....

Abstract:: Russia is experiencing deep structural changes in many areas. For the seafood industry important developments are large increases in household incomes, development of modern super- and hypermarket distribution channels, and product innovations. In the seafood category consumers are adopting new species and new product forms at a rapid rate. Herring...

Creator:: Guettler, Stefan and Mueller, Rolf A. E.
Abstract:: Aquaculture is increasingly important for the future supply of fish because of steadily increasing demand while supply from fisheries is stagnating. In the EU aquaculture production has grown strongly in some countries, such as Spain and Greece, but was flat at a low level in others, such as in Germany,...
