In a 2009 paper in Land Economics, Roy, Arnason and Schrank used a newly developed methodology based on cointegration analysis to establish and measure the role of the fishing industry as an economic base industry (and the only such base industry) for the Canadian province of Newfoundland over the period...
The aim of this work is to develop a predator-prey model for two species of commercial importance captured by the Spanish fishing fleet in the National Fishing Ground (ICES areas VIIIc and IXa). In this model, the Southern hake (Merluccius merluccius) represents the predator, and the blue whiting (Micromesistius poutassou)...

DEVELOPING A PREDATOR-PREY MODEL FOR THE HAKE AND BLUE WHITING
SPANISH
This paper conducts the first empirical investigation of common-pool
resource users' dynamic and strategic behavior at the micro level. We
examine fishermen's strategies in a fully dynamic game that accounts for
latent resource dynamics and other players' actions and recover the profit
structure of the fishery. The ability to measure...
The lessons learned from a review of thirteen bio-economic models are presented. We describe and analyze
how these models equal/ compare and differ in terms of the classification, their biological and economic
modules, the integration between modules, the indicators they provide and indicator use. We pay particular
attention to the...
The objective of this paper is to study the economic management of Eastern
Baltic cod (Gadusmorhua) under the influence of nutrient enrichment. Average
nitrogen concentration in the spawning areas during the spawning season of
cod stock is chosen to be an indicator of nutrient enrichment. The optimal cod
stock is...
Major fishery investment has recently been implemented in West Africa as part of the World Bank's West Africa Regional Fisheries Program. To support this effort the New Partnership for Africa's Development funded development of a Seafood Bio-Economic Assessment Model. The model was initially developed for Ghana, but will accommodate other...
In the Baltic Sea, the successful conservation of grey seals has increased seal-induced damages to the Atlantic salmon fishery. The paper addresses the conflict between the conservation of the formerly endangered species and professional fishermen whose livelihood is also regulated by fisheries management. We develop a bioeconomic model that accounts...

The World Summit on Sustainable Development (Johannesburg, 2002)
encouraged the application of the ecosystem approach by 2010.
We propose a framework that deals jointly with i) ecosystem dynamics,
ii) conflicting issues of production and preservation and
iii) robustness with respect to dynamics uncertainties.
More specifically, we define robust viability kernels...
