Models for Multispecies Management. This item is unavailable.Models for Multispecies Management

The present book summarizes parts of the research made in the Norwegian Multispecies program. This program was initiated by the then Norwegian Council of Fisheries Research, which was later integrated in The Research Council of Norway. Modelling has been a key element in the program. In the first place, modelling, be it singlespecies or multispecies modelling, is an efficient way of summing up existing knowledge, and performing analyses of different types on the basis of it. Further­ more, models may serve as a meeting ground between fishery researchers from differ­ ent academic fields. This has been an important aspect of the Multispecies program, bringing together oceanographers, biologists, economists, mathematicians and stat­ isticians in fruitful cooperation. That this has proved possible may be taken as an important result of the program. The multispecies aspect has perhaps underscored the need for inter-disciplinary cooperation. The different authors are, of course, responsible for their respective contributions. Technical assistance in preparing the manuscript has been given by Knut Arrestad and Ian Knutsen, both at the University of Bergen. Bergen, October 1997.

This book reports modelling work within the Norwegian national research program on multi-species management. The work was concentrated on the interaction between different species in the Barents sea. The book combines contributions from different fields - fisheries biology, ecology, fisheries economics and statistics. In principle, the work covers the whole process related to the management of the ecological system, from plankton inflow, feeding fish stocks, their interaction, economic calculations and finally a general approach to the decision problems for managers. The goal of the program was to develop a decision tool for the Norwegian fisheries management authorities. The book can be seen as a step in this direction.
