The paper examines the determinants in wetland fisheries in the Yala Swamp on the coast of Lake Victoria in Kenya with an aim to guide policy on an integrated approach towards sustainable management of fisheries in all the wetland resources.

Diversity is often associated with resilience but in this model, unobserved genetic or behavioral diversity can explain the collapse of supposedly regulated fish stocks such as cod. Recent studies have shown the existence of separate sub stocks of cod even at a very fine geographical scale.

Using an experimental approach, we investigate the risk preferences of artisanal fishermen in Tanzania waters of Lake Victoria. The experiment concerns pairwise comparisons of hypothetical fishing trips that vary in expected mean and spread of the net revenue.

Namibia’s main linefish species, the kob, is subject to age-specific fishing mortalities that differ for the two fisheries (commercial linefishing vessels and recreational anglers) exploiting it.

This paper reviews the impact of articles published in the Marine Resource Economics (MRE) and within the field of fisheries economics in general over the period 1954–2004. Specific attention is given to the years 1984–2004, which is the period that MRE has been published.

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.
