Hatchery Evaluation - Fall Chinook and Late-fall Chinook

Program Overview

Construction and operation of Shasta Dam resulted in the loss of approximately 187 miles of spawning and rearing habitat for salmonids. The Service produces fall and late-fall Chinook salmon at Coleman NFH to mitigate for this loss of habitat and the consequent reduction in salmonid populations. Fall and late-fall Chinook salmon are produced at the hatchery primarily to contribute to harvest in the ocean commercial fishery, ocean sport fishery, and freshwater sport fishery. Another goal of these programs is to provide adequate escapement back to the hatchery for broodstock. The Service intends to achieve these goals while minimizing negative effects on natural populations.

Battle Creek Run Size Estimates

In 2003, the U.S. Fish and Wildlife Service Hatchery Evaluation program began a cooperative project with the California Department of Fish and Game (CDFG) to use a video monitoring station in Battle Creek to enumerate returns of fall Chinook salmon. The video monitoring station provides the basis for the annual run size estimate produced by the CDFG. Additionally, the “near real-time” information on fish abundance provides a valuable tool to improve management of brood stock collections at the Coleman National Fish Hatchery.

The Battle Creek video monitoring station is pictured at right. Fish are forced by a weir to pass over the white sheet on the bottom of the creek. This creates a contrasting background so an image of the fish can be taken with the video camera (mounted over the white sheet).
