The goal of this study is to validate if the Discounted Survey Life (DSL) /Hydrology method of indexing residence time related to flow timing developed at Burman River can be used more extensively. More specifically we hope to estimate escapement of the adjacent and neighboring Pacific Salmon Treaty (PST) wild population indicators in the Nootka-Kyuquot Conservation Unit (CU) and the Southwest Vancouver Island CU, (Kaouk, Tahsish, and Artlish, Megin, Mooyeha, Bedwell). Modern mark-recapture (MR) methods will be employed at Conuma River and Tranquil Creek, to precisely estimate spawning escapement of Chinook salmon. Although these two streams are not current Pacific Salmon Commission indicators of natural Chinook salmon escapement we believe they contain sufficient fish from hatchery production or supplementation to successfully conduct MR studies, estimate the DSL parameter, and validate if the new method can be applied more broadly to WCVI Chinook in general and specifically to the wild PST escapement indicator populations established in the new Agreement.
