This paper explores the debate on participatory approach by presenting evidence from the local communities practices living within the marine protected area in Tanzania (Mnazi Bay Ruvuma-Estuary Marine Park). Five out of fifteen villages that exist in Mnazi Bay Marine Park were selected for this study after consultation with the park authority. Stratified sampling of villages was conducted based on the location from the Indian Ocean: three villages located close to the sea (sea front villages) and two villages located far from the sea (inland villages).

We examine the welfare implications of the Tanzanian fisheries boom resulting from Lake Victoria Nile perch exports during 1993–2008. In the literature, there are two opposing views on the effect of fish trade: some argue that fish trade can act as an engine of growth, while others contend that trade in fish negatively affects food security, local economies and incomes of the poor.

We develop a decision making model based on constraints that are typically encountered in fisheries management when setting the total allowable quota. The model allows us to assess the differences in outcomes when the decision is made by different management institutions under uncertain conditions.

Traditional sectors such as agriculture and fishing often receive special treatment from policymakers because such sectors are perceived to be associated with traditional cultural public good values. However, these values are often difficult to measure and few attempts have been made to do so.

In this study we analyzed price determination throughout the Chilean hake market chain. To analyze the relationship between different prices which participate in this chain, a VECM model was successfully estimated.

Although Marine Protected Areas (MPAs) are an increasingly popular policy tool for protecting marine stocks and biodiversity, they pose high costs for small-scale fisherfolk in poor countries.

The effect of social capital on the economic performance of artisanal  fishermen organizations that work under a Territorial Use Rights in Fisheries (TURF) system was tested using the social networks approach. The application was based on a sample of artisanal fishers organizations that extract the locally named “loco” (Concholepas concholepas) in Central-Southern Chile. Social networks were measured through organizations’ structural properties and their bonding, linking, and bridging relationships. Economic performance was measured through per capita income.

We study through framed field economic experiment the effects of exogenous changes in abundance levels of a renewable natural resource on compliance individual decisions of users operating under a common property regime and a system of Territorial use rights in fisheries (TURF) considering extraction quotas and external enforcement to detect and sanctions violations.
