Typically, crew members in fisheries are remunerated through a share of the total revenues. However, there is little empirical evidence on the mechanisms by which revenues are distributed to labor and capital, and how these distributions affect economic performance. Under an agency problem framework, we estimate a
Aquaculture is on the most dynamic food production systems in the world, with a fast expansion, especially in developing countries. Among this sector, the Chilean mussel industry has experienced a substantial increase, turning Chile into one of the leading producers and global exporters of mussels. Among the different links in the mussel production chain, the natural seed collection conducted by artisanal fishers of southern Chile has been a fundamental pillar for the development of the industry. Often, this sub-sector has been thought of as a homogeneous group
Given its ability to yield predictions for very diverse phenomena based only on two parameters—body size and temperature—the Metabolic Theory of Ecology (MTE) has earned a prominent place among ecology’s efficient theories. In a seminal article, the leading proponents of the MTE claimed that the theory was supported by evidence from Pauly’s (On the interrelationships between natural mortality, growth parameters, and mean environmental temperature in 175 fish stocks.
This research described in this article aimed to investigate international market potentials for Pangasius catfish (Pangasianodon hypopthalmus). The monthly export data from Vietnam, which accounts for more than 95% of the global export value, in the period 2007 to 2014, were used to estimate a non-linear Inverse Almost Ideal Demand System of the seven market regions.
Fishery management of straddling stocks is conditional on available knowledge about relevant environmental shocks, such as El Niño events, affecting stock behavior. But knowledge of these issues is scant, particularly in developing world fisheries.
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.
