Overseas Doctoral fellowship in fisheries management(del av prosjekt 173476))

The main objective of this fellowship is to apply the generic model of harvest control rules to a case study (Georges Bank haddock) and to interpret end disseminate the results for scientists and managers. This collaboration work will result in the fourth and final of Dorothy?s PhD thesis (working title: ?Harvest control rules applied to Georges Bank haddock?) Other primary objectives include: 1) confirm or reject some of the results of Dorothy?s previous work in the paper ?General properties of harvest c ontrol rules?, by applying the theory of harvest control rules to an actual stock/case study 2) evaluate and analyze the trade-offs and relationships of different performance measures of fisheries managers to each other 3) derive general conclusions as to which harvest control rule design is most appropriate for Georges Bank haddock. Some secondary objectives include analyzing simple rules (i.e. keep the catch constant for 5 years) to see if they tend to perform differently than very detailed rules, exa mining how assessment uncertainty translates into management performance, and to see how sensitive the conclusions are to life history parameters for Georges Bank haddock. Furthermore, concrete management objectives for this stock, central to the root of fisheries management, will be collected, simulated and evaluated. Also included in this overseas fellowship is collaboration with Dr. Steve Cadrin with coordinating the theme session ?Harvest control rules: Experiences in modeling and application? at the Annual Meeting of the American Fisheries Society 2008 in Ottawa, Canada. Besides co-coordinating and leading the roundtable discussion in this international theme session, Dorothy will present her collaborative work here with an oral presentation.
