This article analyzes the effects of the invasion of water hyacinth on fishing in Lake Victoria.

Fisheries in developing countries are often characterized by poorly defined property rights, open access, and overcapitalization. The authors explore how trade liberalization generally is beneficial, but combining it with open access may reduce a country’s welfare and fish stocks, especially when reinforced by bad subsidies.

Trade liberalization may also promote development of property rights in response to increased fish exploitation. The WTO can help facilitate trade by reclassifying subsidies to eliminate bad ones and distinguish good ones.

This analysis of the fishers’ compliance with regulations in Lake Victoria, Tanzania, gives support to the traditional economics-of-crime model and shows that the extension of the basic deterrence model can lead to a richer model with substantially higher explanatory power.

This paper studies technical efficiency and skipper skill (and explores potential proxies), using Tanzanian fishery data for the two major species, Nile perch and dagaa. The relative level of efficiency is high in both fisheries, and several observable variables linked to skipper skill significantly explain the efficiency level. However, given the rapidly depleting fish stocks in Lake Victoria, increased efficiency at the aggregate level is only possible if fishing effort is limited.

This study of the deleterious effect on fishing by the water hyacinth invasion of Lake Victoria found an unusual positive: the decline of fish catchability caused by the the abundance of water hyacinths has paradoxically stopped or at least postponed serious overfishing.

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.
