The translation of fisheries assessment uncertainty to a risk analysis for immediate management actions in relation to established harvest strategies has influenced the development of recent management plans in Atlantic Canada. Graphics depicting the risk of failing to achieve exploitation and biomass targets for a range of quotas were included with the scientific resource evaluations for Gulf of St. Lawrence cod and eastern Georges Bank haddock. The risk analysis framework for providing advice on forecast scenarios changed the emphasis from recommending the "best" action consistent with the harvest strategy to measuring the performance of alternate actions relative to the harvest strategy. Evolution away from a single option promoted communication between stakeholders and scientists and provided the opportunity for stakeholders to effectively participate in the decision process. Success was dependent on management institutions to cope with implementing a range of actions, timely use of current information, deliberate and thorough presentation of risk results, and previous exposure to risk analysis.
