Creator:: Boudribila, Youssef and Wilson, James R.
Abstract:: We focus on problems of access to marine sites for aquaculture in different countries, particularly in Maine, U.S.A. and Canada. The main question examined is how public natural goods (marine space) are allocated for aquaculture activities. Using ideas from law and economics, as well as institutional economics, we looked at...

Creator:: Miller, Kathleen, Munro, Gordon R., and Bjorndal, Trond
Abstract:: Long-term climate regime shifts have profound and persistent impacts on ocean temperature and circulation patterns, and on the dynamics of marine fish populations -- affecting abundance, growth and migratory behavior. Such shifts are a particularly important source of uncertainty for marine fisheries. Here, we argue that climate regime shifts can...

Abstract:: In this paper we analyse different econometric procedures of technical efficiency to estimate fishing capacity. These procedures are then applied to the purse seine fishery located in the Gulf of Cádiz. The target species of this fishery has changed quite a lot over the past few years. It used to...

Abstract:: Crown jellyfish (Periphylla periphylla) has become an increasing biological and economic problem for the fishermen in many Norwegian fjords. It is known to prey on a variety of planktonic species including small crustaceans like krill and calanus as well as fish eggs and larvae. Thus, this jellyfish is both a...

Creator:: Sandberg, Per and Nedreaas, Kjell Harald
Abstract:: Fisheries affect fish stocks through their exploitation rate and exploitation pattern. Both influence the economic yield from the fish stock. In regulated fisheries, the exploitation rate is determined either by the acceptable level of fishing effort or catch, whereas the exploitation pattern is determined by selectivity of gears and/or regulatory...

Creator:: Poudel, Diwakar and Steinshamn, Stein Ivar
Abstract:: This study investigates optimal catch of Barents Sea stocks, namely Northeast Arctic Cod and Capelin in multispecies ecosystem. We solve a multispecies age structured bioeconomic model for predator-prey interaction. Barents Sea stock data from ICES are employed for model application. Among others, we also include sustainability constraint in the model...

Creator:: Hersoug, Bjørn
Abstract:: Norway has for years managed its coastal fisheries through a regime that for all practical purposes has acted as open access, that is, open for bona fide fishers. The trawling sector was closed already in the 1930s, and the large offshore fleet was regulated through limited entry licensing from the...

Creator:: Asche, Frank, Bjorndal, Trond, and Gordon, Daniel V.
Abstract:: Traditional fisheries management schemes provide fishermen with incentives to maximise their individual share of the catch, while individual vessel quota management schemes change incentives to maximise profits from their individual share of the catch. The way that one models the fishermen’s optimisation problem in empirical studies should reflect the changed...

Creator:: Lorentzen, Torbjørn
Abstract:: Global warming is expected to affect the ecosystem in the Northeast Atlantic, and sufficient changes will also affect the aquaculture industry. Farming of salmon and trout is the biggest aquaculture industry in Norway. The export value was about 2 billion US dollars in 2005. The objective of the paper is...

Abstract:: This study suggests an optimal harvest policy for Barents Sea species, namely Northeast Arctic Cod (Gadus morhua) and Capelin (Mallotus villosus) in the multispecies ecosystem. We have solved a multispecies age structured bioeconomic model for predator-prey interaction. Barents Sea stock data from ICES (International Council for the Exploration of the...
