| Intensive fish farming has faced a number of environmental challenges both locally and globally. In this paper we review some of the most important environmental issues that has faced fish farming and then see how the industry has handled these challenges. Salmon aquaculture has probably faces more of these challenges than any other farmed species, with the possible exception of shrimp aquaculture. We concentrate on empirical evidence related to salmon, although the issues related to other farmed species are similar to that of salmon. Other environmental issues include degradation of local habitat, disruption of ecological systems, and detrimental impact on wild species. Evidence suggests that most of the local environmental problems have been... |

| During the last two decades there has been a tremendous growth in the production of intensively farmed fish. This growth has been accompanied by a substantial reduction in prices. As this enhances the competitiveness of farmed fish, concerns are often raised with respect to the market impact of new aquaculture species. Of particular interest is the relationship to wild species in the output market as well as in the input market because of the demand for feed. In this paper we investigate what we know about market interactions based on two simple market models, where the difference between the two models is whether the competing product is wild-caught seafood or a traditionally produced product. |
