This paper measures for potential profit in the North Sea mixed demersal fishery for cod, haddock and whiting. Dynamic bioeconomic models for three UK fisheries are developed, incorporating both population dynamics and economic structure. Actual profit in 2006, for the three UK fleets included in the analysis, is estimated at £10.3 million. If the TAC remains unchanged but vessels are allowed to harvest at near efficient levels with fleet size reduced accordingly, potential profit is measured at £34.5 million.

EfD-Kenya actively participated in the preparation of the Kenya State of Environment (SoE) Report 2010. EfD-K Researchers Dr. Wilfred Nyangena and Geophrey Sikei were authors in the report. Dr. Nyangena was the Lead Author for Chapter 11 of the report which dealt with Policy options for action. Geophrey was a contributing author in Chapter 11 and Chapter 6 dealing with Land, Agriculture and Livestock.

This note acknowledges Jens Warming's contributions (1911, 1931) on what has since come to be known as the open access problem in fisheries. Warming, in a static framework, suggested an optimal landing tax before Pigou (1920) and described the sole owner solution later suggested by Scott (1955b). I describe these results using Warming's framework and point to his previously overlooked contribution concerning the dynamic aspect of fisheries.

We study dynamic labour supply using data on paua (abalone) divers in New Zealand. The divers face stable, flat prices per kilogram after each catch, but experience transitory wage changes due to varying weather and water conditions, and are free to vary their daily working hours and display an intermittent working pattern. We find nonlinear wage elasticities, rejecting the standard neo-classical prediction that these divers should work long hours during days when wages are high and quit early during days when hourly wages are low.

Although Marine Protected Areas (MPAs) provide an increasingly popular policy tool for protecting marine stocks and biodiversity, they pose high costs for small-scale fisherfolk who have few alternative livelihood options in poor countries. MPAs often address this burden on local households by providing some benefits to compensate locals and/or induce compliance with restrictions.

Marine Protected Areas (MPAs) in poor countries typically address the impact of fishing restrictions on rural resource-dependent villagers because of their mandate and because achieving conservation goals requires altering household fishing behavior.

This paper explores the issue of “trust” in the fisheries science community, a key corollary of effective risk communication. It presents the findings of a survey undertaken in Iceland, Greece, Spain, United Kingdom and Faroe Islands during 2008. The findings reveal differing levels of trust and mistrust in the fisheries science community between countries and between stakeholder groups, demonstrating areas for future attention in the interests of improving fisheries science and management.

In this study we seek to explain the determinants of catches for the Nile perch and tilapia fisheries of Uganda’s section of Lake Victoria. Production functions are estimated from data collected from a survey of 100 boats engaged in fishing of Nile perch, and 150 boats fishing tilapia, in 3 districts along Lake Victoria.
