This paper assesses the potential for rent generation in the North Sea herring fishery. The assessment distinguishes between rents and intra-marginal profits—the sum of which constitutes variable profits in the fishery. A bioeconomic model combining fish population dynamics and the economics of the fishery is constructed to allow the computation of these different components of profits. In order to assess the dynamics of both rents and intra-marginal profits, the model is computed under various assumptions with regard to price, costs, and discount rates.

This paper explores the factors underlying both innovation choices and intensity among small-scale aquaculture producers. 

We test if the establishment of salmon farms in remote coastal areas had a significant impact on poverty reduction in the period 1992–2002 in Los Lagos Region, Chile.

This article analyzes the initial effect of introducing a cooperative catch shares allocation system (CCS) on the technical efficiency of artisanal vessels operating in pelagic fisheries in south-central Chile.

La Flor Wildlife Refuge and nearby beaches on the Pacific coast of Nicaragua are important nesting sites for various species of endangered marine turtles. However, illegal harvesting of turtle eggs threatens the survival of marine turtles. In this study, we analysed the different motivations of local villagers for complying with a ban on harvesting marine turtle eggs in a context, in which government authorities do not have the means to fully enforce existing regulations.

We present a novel policy framework to evaluate and pursue growth in aquaculture considering four boundaries: biological productivity, environmental constraints to that productivity, policy that inhibits or promotes different kinds of aquaculture, and social preferences that determine aquaculture markets.

Small-scale farming of mud crabs (Scylla serrata) has been suggested as an alternative income for resource poor coastal communities in East Africa. However, it and it is unclear if the present culture methods are profitable and ecologically sustainable at larger scales. Here we assess the two dominant culture methods (crab fattening in cages and grow-out farming in ponds) using economic and ecological analyses in Kenya and Tanzania.
