Creator:: Armstrong, Claire W.
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:: Poor selective gears like bottom trawlers are known to induce joint productions ie catch of several categories of fish by targeting one category in particular. Joint productions can be inter-species or intra-species. They can be retained to be sold or discarded most of the time with high mortality rates when...

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...

Creator:: Bui, Xuan and Armstrong, Claire
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:: 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:: 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...

Creator:: Macher, Claire, Guyader, Olivier, and Boncoeur, Jean
Abstract:: This paper proposes a formal analysis of the discarding issue including the sorting labour costs. Empirical evidences from an application to the Nephrops fishery in the Bay of Biscay show that sorting is an important time consuming activity on board and a factor of discarding. However existing literature does not...

Creator:: Aanesen, Margrethe, Armstrong, Claire, and Kahui, Viktoria
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...

Creator:: Bellanger, Manuel, Merzereaud, Mathieu, Guyader, Olivier, and Macher, Claire
Abstract:: Integrating governance mechanisms into bio-economic modeling tools is a key challenge for the assessment of fisheries management plans. Impact assessments are carried out without considering real management options and institutional context. Only fishing mortality changes and their impact on fish stocks are considered. The Bay of Biscay sole fishery offers...

Abstract:: This study identifies differences in fishing efficiency of vessels operating in the Nha Trang purse seine fishery in Vietnam. The deterministic DEA methodology is used to assess relative capacity utilization of the fishing fleet. Double bootstrap DEA method is adopted to overcome some of the drawbacks of nonparametric DEA methodology...
