Whether drastic drops in population abundance is the result of fishing or climate change is a never ending debate among fishery managers and our project will add to the scientific underpinning needed to resolve such issues. The main objective of this project is to improve our understanding of how fishing mortality and climate change and variability affect marine fish population dynamics. We will study the effect of average level and variance in fishing mortality and environmental factors on fish demography and population dynamics. The relative effect of fishing and climate driven long- and short-term variation in environmental conditions will be addressed within the framework of stochastic demographic models, which will be applied to real systems including cod and vendace in the Baltic sea and several fish species in Skagerrak and Kattegat. By making use of Markov Chain Monte Carlo methods we can acknowledge the full structure and complexity of natural populations when estimating parameters and functional relationships. Stochastic elasticity patterns will be compared with risk analysis using simulations in terms of credibility as guidance to management. Finally, the performance of alternative fishing strategies under different environmental conditions will be evaluated.
