The international State of the Salmon 2009 Conference was held in Vancouver, BC, Canada from February 2 to 5 to discuss Pacific Rim wild salmon conservation. Although ‘wild salmon conservation’ is not a priority in Japan due to the successful salmon hatchery-based management, it may be time to change. The conference and the challenge in Hokkaido is discussed.

The primary purpose of this paper is to provide evidence to a hypothesis: the temporal breadth for potential spawning is so broad for male steelhead/rainbow (Salmon mykiss in Russia, Onchorynchus mykiss in North America) that it is impractical and perhaps impossible to effectively manage for temporal isolation of wild and hatchery steelhead when they cohabit mutual spawning areas. It is proposed that if this hypothesis is correct, then there has been a reshaping of wild steelhead/rainbow populations through fishery management in North America when and where management has been based on the assumption that wild and hatchery steelhead can be temporally isolated from spawning together.

The overall effect of these impacts across the watershed has been a simplification of habitats and the biotic communities that they support. In order to help populations of fish, wildlife and plant species recover, some conservation and restoration activities need to take place.
