Economic Impacts of Global Warming : The Case of the Barents Sea Fisheries
Regional analyses of possible physical and biological effects of global warming in the Barents Sea area have been carried out recently. Based on such studies possible economic impacts of global warming on the Barents Sea fisheries have been quantified, assuming different types of management regimes. The EconSimp2000 model, consisting of the ecosystem model AggMult and the fleet model EconMult have been parameterized based on fleet and catch records from the Norwegian Barents Sea fisheries. The model has been used to study biological and economic impacts of different environmental scenarios representing possible consequences of global warming. The current environmental situation, including normal seasonal and other variations, has been used as a reference scenario. Several biological and economic indicators have been defined in order to evaluate the simulation results of different environmental scenarios and different types of management regimes. The findings support earlier studies where biological and economic impacts of changes in management regime is found to be more pronounced than impacts caused by effects of global warming.

Dyspriani, Polite (Master thesis; Mastergradsoppgave, 2007-05-29)Shrimp world production in the last few years has shown very high growth rates. It is marked by an increasing of production volume, and by shifting from capture to aquaculture fisheries within the production system. This has occurred mostly regarding to the brackish water pond. For some years, the government has had to face hard choices in order to ensure shrimp aquaculture developed sustainable. ...
Karlsen, Kine Mari (Doctoral thesis; Doktorgradsavhandling, 2011-08-26)The purpose of this thesis was to study granularity and its importance for traceability in seafood supply chains. The following hypothesis was applied in this thesis: The implementation of traceability of seafood is affected by the granularity level of the traceable units. Three sub-tasks were carried out to test the hypothesis: 1) identify critical traceability points (CTPs) of seafood products, ...
Nolde Nielsen, Kåre (Doctoral thesis; Doktorgradsavhandling, 2008-11-21)What is the relationship between science and politics? What should it be? How are their respective roles conceived and acted out in practice? Should science and politics be clearly separated? How? Are there cases in which they can be usefully mixed? What cases are those, and are there some ways of mixing that are better than others? This project explores such questions by examining relationships ...
