  4. Harvest Control Rules

  5. Harvest Control Rules FAO Fisheries Glossary definition: Describes how harvest is intended to be controlled by management in relation to the state of some indicator of stock status. For example, a harvest control rule can describe the various values of fishing mortality which will be aimed at for various values of the stock abundance. It formalizes and summarizes a management strategy. Constant catch and constant fishing mortality are two types of simple harvest control rules. Restrepo V. (1999): Annotated Glossary of Terms in Executive Summary Reports of the International Commission for the Conservation of Atlantic Tunas´ Standing Committee on Research and Statistics (SCRS). ICCAT.

  6. Observation error • Uncertainty • Implementation error Expectations Objectives Evaluation of candidate HCRs Harvest Control Rule Stock status  Control Evaluation of performance

  7. Experience from harvest control rules in management of fisheries in the Nordic seas Expectations on HCRs and fisheries management by various stakeholder (fisheries scientists, managers, fishermen, environmental groups) How theoretical analyses on HCRs can help us to understand the potential benefits and limitations of HCRs? Can objectives of all stakeholders be meaningfully represented in theoretical evaluations of HCRs? Comparisons of existing HCRs. Can they be improved? This workshop

  8. 24 research scientists (16 outside IMR) 2 fisheries managers 2 representatives of fishing industry 1 representative of NGOs 1 science administrator Who are we?

  13. ? Personal experience: blue whiting Shall strong recruitment continue?

  14. HCRs (as we know them now) focus on single species – ecosystem aspects??? Should information on the environment be a part of the input to a HCR? Exit rules/domain of validity: a HCR should be able to cope with some – but not all – variation in the fishery system Does increasing complexity help? Challenges & questions
