Audience:  Government and Public
Since 1994 the upper Sustut River summer-run steelhead stock has been used in a standardized manner as an annual indicator of stock status for all early run Skeena River summer steelhead Oncorhynchus mykiss. These stocks are of management concern as their early run timing coincides with marine mixed stock commercial fisheries for sockeye O. nerka and pink O. gorbuscha salmon where they are captured incidentally Ward et al. 1993; Cox-Rogers 1994. Due to their long freshwater migration, Sustut River steelhead are also intercepted in First Nations fisheries and catch and release recreational fisheries on the Skeena River and lower Sustut River. Annual enumeration of the upper Sustut River steelhead stock provides yearly spawning population estimates that are hypothesized to demonstrate trends in the abundance of all early run Skeena steelhead.
