The study of fisheries-induced evolution is a research field which is becoming recognized both as an important and interesting problem in applied evolution, as well as a practical management problem in fisheries. Much of the research in fisheries-induced evolution has focussed on quantifying and proving that an evolutionary response has taken place, but(More)
measures and fishers' commitment to sustainable exploitation: a case study of Atlantic salmon fisheries in the Baltic Sea. Fisheries management aimed at sustainable exploitation may affect fish populations indirectly by influencing human behaviour. We propose a methodology that includes stakeholders' opinions, perceptions, and resulting behaviour, within(More)
Reaction of fishers is an essential source of uncertainty in implementing fishery management decisions. Provided they realistically capture fisher behaviour, models of fishing vessel dynamics provide the basis for evaluating the impact of proposed management strategies. Information flow among vessels has not been a major focus of such models however,(More)
This overview article for the special series, "Bayesian Networks in Environmental and Resource Management," reviews 7 case study articles with the aim to compare Bayesian network (BN) applications to different environmental and resource management problems from around the world. The article discusses advances in the last decade in the use of BNs as applied(More)
NB. The HIIT Technical Reports series is intended for rapid dissemination of results produced by the HIIT researchers. Therefore, some of the results may also be later published as scientific articles elsewhere. Abstract: In electrofishing it is usually assumed that the abundance of fish at a site is strongly dependent on habitat type. In practice the(More)
NB. The HIIT Technical Reports series is intended for rapid dissemination of results produced by the HIIT researchers. Therefore, some of the results may also be later published as scientific articles elsewhere. Abstract: From the management point of view, the production of wild smolts is the most important indicator of the status of a river's salmon(More)
Understanding and managing ecosystems affected by several anthropogenic stressors require methods that enable analyzing the joint effects of different factors in one framework. Further, as scientific knowledge about natural systems is loaded with uncertainty, it is essential that analyses are based on a probabilistic approach. We describe in this article(More)
We take a decision theoretical approach to fisheries management, using a Bayesian approach to integrate the uncertainty about stock dynamics and current stock status, and express management objectives in the form of a utility function. The value of new information, potentially resulting in new control measures, is high if the information is expected to help(More)

Abstract: We present a methodology allowing the transfer of knowledge from a wild salmon river to another via a predictive model for the chosen(More)
