Cod on the menu? Using mathematical modelling to provide fisheries management advice

Cod on the menu? Using mathematical modelling to provide fisheries management advice

Scientific advice on the management of fish stocks is often informed by mathematical assessment models that fit to information from catches, research surveys and life history. North Sea cod is a high-profile and commercially important stock with a long history of highs and lows. In particular, the latest assessment estimates that the stock is below safe biological limits, which comes just two years after the fishery was certified sustainable.

Using North Sea cod as a case study, Dr Walker will present the state-space assessment model (SAM) and detail the process of turning model outputs into scientific advice for fisheries management. She will discuss diagnostics for assessing the quality of input data and model fits and highlight some of the problems facing the assessment of this stock.
