In this paper an unregulated, but not open-access, fishery is studied and it is analyzed how more modern fishing technology may be a mixed blessing not only for the fish abundance, but also for the rent. The model is formulated in section two where it is included a strategic interaction...
This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that...
A discrete-time bioeconomic model of two stocks is presented, where one of these two stocks can be partially protected by a reserve or some other hindrance to harvesting. The interaction between the two stocks is geographic, in the sense that the protected stock can migrate out of the reserve and...
This paper explores the optimal management strategies of two species with different life history traits. Here we consider a prey-predator relationship which may represent a resident species and an invasive species. They have different life history traits and interact by competing food and space and predation in the same ecosystem....
The paper is the first attempt to explore the ecological and economic impacts of genetic interaction between farmed and wild salmon over generations. An age- and stage-structured bioeconomic model is developed. The biological part of the model includes age-specific life history traits such as survival rate, fecundity, spawning success for...
Researchers rely on bioeconomic models to guide research and generate fishery management advice for commercial fisheries. Due partly to a paradigm shift towards ecosystem based fishery management, increasing complexity in the characteristics of the problems has meant that bioeconomic simulation models are becoming more prevalent in the fisheries literature. However...
