Climate change and annual fluctuations of environmental conditions strongly affect fish stocks and all biological ecosystem components. Evaluating fisheries management strategies should include environmental information as part of the decision basis. Estimation of how often an undesirable event may occur, and what the consequences would be of such an event needs to be estimated through a risk analysis using stochastic simulations.
