This document was produced during a three-day seminar and workshop on the genetic diversity of commercially exploited fish species in Nordic waters held at Hólar College, Iceland. The aim of the seminar was to discuss current knowledge regarding the effects of commercial fishing activities on the genetic diversity of wild, marine species of fish in Nordic waters, and to provide recommendations for necessary actions to minimize further loss of such diversity. This document expresses the joint view of the selected expert scientists invited to the meeting (Appendix 1), and the content concerns fish populations exploited in Nordic waters.
