Washington and Oregon fishery managers will host a public meeting in The Dalles on Wednesday to discuss sturgeon fishing regulations upstream of Bonneville Dam.  Among the topics of discussion are possible rule changes meant to improve conservation efforts and increase the abundance and survival of mature spawning-size sturgeon.  Those include extending the dates of all sturgeon spawning sanctuaries in the Columbia River from Bonneville Dam to Priest Rapids Dam through August 31.  Most are currently in effect from May 1 through July 31.  Also to be discussed is extending the area of the spawning sanctuaries on the Columbia River below McNary and Priest Rapids dams.  The meeting will be from 6 p.m. to 8 p.m. Wednesday at the Oregon Department of Fish and Wildlife screen shop on 3561 Klindt Drive in The Dalles.
