This report forms just one part of an integrated research effort on the BCLME fisheries being carried out by “The Consortium”. It is anticipated that, as the rest of the BCLME projects advance, new information relevant to this study will come to light. This is particularly true for project LMR/SE/03/03, for example. The Consortium wishes to reserve the right to update this marketing report if and when the relevant information becomes available.

A fishery run as a perfect monopoly seeking to maximize its profits over time, and secure in
its monopoly rights, will try to maximize the present value of its economic rents or profits over
time. To do this it will have to exploit the resource sustainably, keeping up the level of the
resource so as to keep up its catch per unit effort, and keep down its costs.

The most important Namibian linefish species, the silver
kob Argyrosomus inodorus, is currently heavily
exploited, and in order to ensure its survival catch
restrictions are being introduced. However, kob are
exploited both by recreational anglers and by commercial
vessels, and it is important to examine the economics
of these fisheries in order to determine where catch
restrictions will do the least harm to the economy.

Eishers are risk-averse according to most empirical studies, while expected-utility theory predicts risk neutrality even for sizable stakes.

We present a model of fishers’ gear choice, which allows for heterogeneity both in production technology and risk preferences and apply it on a panel of Swedish trawlers.

The results from a survey of Swedish commercial fishers on regulation compliance and attitudes to control and restrictions are reported. According to the responding fishers, 90% of all Swedish catches are reported, in spite of limited control efforts.

Parameter values for the von Bertalanffy growth model are estimated for Nephrops norvegicus in the Skagerrak on the Swedish west coast using analysis of length frequency distribution from commercial catches and tag-recapture data.

This article discusses the underlying causes for the problem of managing fish stocks and the
aim of fisheries management.It reviews some of the research development in the area and practical experiences. Further, it deals with the future challenges and discusses potential successful strategies and outlines the necessary conditions for actual progress from the current state.

This article discusses bioeconomic analysis and different management strategies in fisheries. It reviews recent developments, which show the need to expand the analysis to multispecies fisheries and management.
