This paper explores the issue of using marine reserves in combination with quotas as fisheries management tools. The underlying biological dynamics are described by a patchy environment model, in which a metapopulation is built up by linked sub-populations that are distributed across a set of spatially discrete habitats or patches....
In this paper an extended version of the well-known Faustmann model is developed for solving the rotation problem in fish farming. Two particularly important aspects of the problem are emphasized: namely first, the possibilities for cycles in relative price relationships and second, the problem with limitations in release time for...
This paper is a study of the production technology and relative efficiency of vessels harvesting tiger prawns in the northern prawn fishery (NPF), one of Australia’s largest and most lucrative fishing areas. It is based on a unbalanced panel data set of 228 observations among thirty-seven vessels for the years...
Main research question: How is seafood consumption influenced by overweight and health beliefs in a region of traditional high-level fish consumption? Materials and methods: A randomly drawn sample of women aged 45-69 years who live in Northern Norway answered a self-administrated questionnaire about eating habits, socioeconomic factors and questions related...
Current fisheries management approaches based on centralised government intervention have proven inadequate to deal with the present management and cannot meet its objectives including reverting stock depletion, resolving user group conflicts, increase profitability and prevent social disruption. There is no easy solution to this problem. New institutions enabling fishing communities...
In 1998, the National Marine Fisheries Service (NMFS) launched a series of marine recreational angler expenditure survey in the Northeast (NE) management region (Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, and Virginia). This series was extended to the Southeast (SE) management region (North Carolina,...
Globalization may affect companies in the fish-processing industry in many ways. For some, globalization poses new threats, for others it represents new opportunities. Some companies see their benefit of being located close to the resources vanish, as resources are brought out of the region, processed in low-wage countries, and distributed...
Atlantic salmon aquaculture is a growing industry in the Bay of Fundy on Canada’s Atlantic coast. The vast majority of aquaculture sites are concentrated in a relatively small coastal region of the province of New Brunswick (NB) where the industry is viewed as a major component of regional economic development....
The French Norway lobster (Nephrops norvegicus) fishery situated in the Biscay Bay is composed by about 250 costal trawlers. These boats are registered in harbours located in South Brittany (Le Guilvinec, Lorient, Concarneau) and in the Vendée (Sables d'Olonnes, La Cotinière). The main particularity of the fishery is that lobsters...
Effects of age, period and birth cohort on consumption of fat fish, lean fish and processed fish were estimated based on panel data from the Norwegian Women and Seafood Consumption Study (NOWAC). Cohorts selected for the present analysis were women born between 1951 and 1966. Survey questionnaires were mailed to...
Western Australia operates a diverse enforcement and education program aimed at achieving high compliance in a wide range of commercial and recreational fisheries managed using a mix of input and output controls. Since enforcement resources are invariably insufficient to totally eliminate non-compliance with fishery rules, it is important to ensure...
The aim of this paper is to assist teaching undergraduate students how to analyse the issue of fish stock investment. The mathematical prerequisites are a basic knowledge of calculus. Both discrete and continuos time frameworks are used. To fish down or to build up a fish stock takes time, and...
Fisheries economists have studied fisheries managed with ITQs and compared them to fisheries that are differently managed. Most of these studies have found ITQs to be economically superior. This paper studies the ITQ-fisheries in Iceland. It focuses on features that are difficult to explain using traditional fisheries economics. It is...
A recent study in agricultural products has brought out evidence of asymmetrical transmission of price changes according to the sign (positive or negative) of past variation. Interestingly, asymmetry was more commonplace for products with a lower elasticity of supply due to the perishable nature of products. A similar study based...
