There is a general concern for the status of Skeena River summer steelhead stocks - particularly for those runs that enter the Skeena early in the season during an intensive commercial fishery targeting mainly on sockeye and pink salmon. B.C. Environment is concerned that interception of these early-run fish may be decimating this component of the steelhead stocks in the upper Skeena tributaries, in some instances to the point of extinction.

There is a general concern for the status of Skeena River summer steelhead stocks - particularly for those runs that enter the Skeena early in the season during an intensive commercial fishery targeting mainly on sockeye and pink salmon. B.C. Environment is concerned that interception of these early-run fish may be decimating this component of the steelhead stocks in the upper Skeena tributaries, in some instances to the point of extinction. Upper sections of the Sustut, Morice and Zymoetz rivers are areas where summer steelhead arrive in the upper river during August and early September and where this early component is threatened.
Surveys of juvenile steelhead fry and parr abundance were conducted on four steelhead systems tributary to the Skeena River in northwestern B.C. during August and September, 1992. The four systems assessed were the Kitwanga, Morice, Sustut and Zymoetz (Copper) rivers. This is the second consecutive year of surveys in these systems.
