En quelques années, l'Indonésie est devenue un des premiers pays producteurs de crevettes. L'extension et l'intensification rapide des élevages a des répercussions socio-économiques et écologiques majeures. Après un pic de 130.000 tonnes en 1992, la production est tombée à 100 000 tonnes en 1993. Depuis, le développement de nouveaux sites...
In considering fisheries regulation in the next decade, I make a concluding point that may become a major theme. This is that individual permanent catch quotas of a regulator-determined TAC are only a stage in the development of management from licensing to private rights (Scott 1989). The condition of open...
Catering establishments in Finland are very heterogeneous (restaurants, hotels, personnel canteens, hospitals, schools etc.). These kitchens annually prepare over 600 million meals with the total number of kitchens at over 20,000. The objective of this study was to estimate quantity and frequency of fish consumption within the Finnish catering market....
Japan is both the largest producer and consumer of tuna in the world. However, Taiwan has been a major exporter to Japan of Thunnus albacares and Thunnus obesus recently. For example, the market shares of Taiwan's supply are 20% for T. albacares, and 44% for T. obesus in 1992. Hence,...
The aim of this paper is to specify the arising preferences within a theory of demand for seafood products through a socio-economic quantitative analysis. The relevance of standard economic variables is discussed by introducing additional socio-demographical variables in a multivariate statistical analysis. The position of seafood among other food products...
The main research question in this paper is: What impacts do the perceived structural changes in (1) consumer demand for fresh quality and (2) mobility (trade) barriers in distribution have on the market and trade patterns for fresh packed consumer fish products? A representative sample of UK and French seafood...
An ITQ scheme has been shown to create a quota induced incentive for discarding of fish in excess of what is socially optimal. This finding is corroborated by empirical evidence in several ITQ managed fisheries. The incentive for discarding, over and above those expected in an unmanaged or input controlled...
The last three years RIVO-DLO and LEI-DLO have developed a bio-economic simulation model for the Dutch beam trawl fishery. At the VII th IIFET conference in Taipei (1994, Taiwan) some preliminary results were presented and at the 4th EAFE bio-economic modeling workshop in Edinburgh (1995, United Kingdom) the final model...
Sustainable aquaculture can be achieved when risk and uncertainly are incorporated in the analysis of the activity. This paper presents a precautionary approach to the feasibility analysis of a project for a commercial hatchery, applying decision theory. Two production scenarios were assessed, continuous and periodic, the later a combination of...
La lagune de Nador se caractérise par un écosystème semi-fermé, en communication avec la mer par une étroite passe. Cet écosystème est sous l'influence de plusieurs facteurs externes tels que l'ensoleillement, l'apport en eau douce, les eaux de ruissellement, le lessivage des champs agricoles et les eaux usées urbaines. L'influence...
