  • Generalization of Age-Structured Models in Theory and Practice

    Creator:
    Steinshamn, Stein Ivar
    Abstract:
    A generalization of the harvesting functions and the stock updating functions in age-structured bioeconomic models is outlined. Using this generalization everything from completely uniformly distributed fish to extreme schooling is taken care of. The classical Beverton-Holt model comes out as a special case of the generalized model. Both the theoretical...

    Creator:
    Ekerhovd, Nils-Arne and Steinshamn, Stein Ivar
    Abstract:
    Optimal management of herring, mackerel, and blue whiting in the North East Atlantic is analyzed. The main motivation is to quantify the potential gain from implementing multi-species management compared to traditional single-species management. The objective is to maximize discounted net revenue; in other words a sole-owner perspective. The results are...

  • Is There Hope for Fisheries Management?

    Creator:
    Schrank, William E.
    Abstract:
    Fisheries is not the only discipline where models have been used in attempts to fine tune an aspect of the economy. Such fine tuning can prove ineffective because of the uncertainties in the scientific underpinnings of the models and because of the omission of critical elements. In fisheries, the biological...
