Abstract:: In this paper we will study two auctions for fish found in Norway, and compare them applying auction theoretical assumptions. We will use the revenue equivalence theorem as a basis to explain why these two different auction mechanisms are chosen for the sale of fish. It is shown that the...

Abstract:: This paper models and investigates the foreshortening of transferred quota which is applied in the Norwegian fisheries management. This reduction in the transferred quota amount by 20% is then redistributed amongst all vessels in the relevant vessel group. It is shown that fishing units can be expected to be operated...

Abstract:: A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...

Abstract:: Protected areas (PAs) are important for biodiversity conservation and can provide the benefits for current and future generations. Management effectiveness is a key factor to achieve outcomes of PAs. However, success is related to the enforcement implemented. Corruption is one of the main issues impacting and weakening enforcement. This article...

Abstract:: The push for ecosystem based management has opened up not only for including more of the natural systems when managing fish resources, but also a broader perspective on the human systems, and the diverse activities in the sea. This is reflected for instance in the EU Maritime Policy where fisheries...

Abstract:: European fisheries activities are subject to a hierarchy of regulatory authorities. This raises questions regarding the implications of strategic interaction between different authority levels concerning the regulation of these activities. We apply a bio-economic objective function where fishers and regulators have environmental, economic and social preferences, and where fishers are...

Abstract:: The state of habitats is important for their productivity, including for stocks of commercial fish. Some fishing methods can damage habitat or give bycatch of species. Destructive fishing gear has sometimes been introduced without awareness of the direct negative impacts on habitat, and without realising the possible negative indirect impacts...

Abstract:: This paper presents a deterministic bioeconomic model with a marine protected area (MPA) including both fisheries management and tourism development goals. A weighting parameter is added to the model to allow tradeoffs between management preferences regarding the two sectors affected by the MPA. The theoretical model is illustrated with analysis...

Abstract:: The rapid growth of aquaculture affects wild fisheries in several ways. We present a bioeconomic model of the interaction between capture based aquaculture that depending on harvest of wild juvenile organisms with a wild fishery, including an effect of marine reserve implementation. We assume the catch of wild juveniles for...

Abstract:: La pêcherie martiniquaise se trouve aujourd'hui dans une situation paradoxale : d'un côte elle se veut résolument moderne de par 1) les embarcations et des outils de production de plus en plus sophistiqués (coques rapides sur-motorisées, GPS, etc.) que les pêcheurs acquièrent a grands frais; de l'autre, elle reste séculaire...
