Identification of Columbia Basin Sockeye Salmon Stocks Using Scale Pattern Analyses in 1993
In 1993, the seventh year of the Columbia River Inter-Tribal Fish Commission’s Sockeye Salmon stock identification research, a representative sample of the Columbia Basin Sockeye Salmon population was obtained at Bonneville Dam while an Okanogan known-stock sample was collected from Wells Dam (Columbia River km 829). A mixed Wenatchee-stock sample was collected at Tumwater Dam (Wenatchee River km 31) consisting of Sockeye Salmon of natural origin as well as unmarked fish from a hatchery/net-pen supplementation program. A small sample was also collected from the Methow River. The scales were examined to estimate the age of the fish and were also measured and used in stock identification experiments.
