Seminar Series: Harvest Strategies to Respond to Climate Induced Changes in Productivity
Abstract
The ability to track and respond to climate-induced changes in the productivity of marine fish stocks presents several challenges in the stock assessment and management process. Some stocks have significant climate covariates; however, for most stocks, the mechanisms by which climate affects productivity are as yet unknown. Biological reference points depend on the life-history parameters of a given stock and are most sensitive to changes in the recruitment rate. Dynamic reference points are a relatively novel strategy to account for climate-induced changes. In turn, such reference points can be used to construct time-varying harvest control rules that respond over time to reflect changes in recruitment productivity and improve recruitment forecasts. This seminar will explore the recent research on the concept of dynamic reference points and provide a case-study where it has been applied to fishery management of winter flounder.
