Sockeye. Chum. and Pink Spawning channels, lake fertilization, barrier removal, and habitat improvements are the primary enhancement methods for sockeye, pink, and chum salmon. DFO biologists recently constructed a new spawning channel at Glendale Cove on Knight Inlet that will potentially produce 1 million adult pink salmon annually. Channel production has realized an egg-to-fry survival of 81 percent (Anon. 1989b). The channel addresses natural low flow problems by drawing water through a pipeline from Tom Browne Lake. Lake fertilization increases production in th salmon. Fertilization takes the place of the adults that once fertilized these lakes. e enhancement of sockeye, pink, and chum thousands of carcasses from spawned out Coho Biologists from DFO primarily use natural and semi-natural enhancement and secondary hatchery production to supplement coho salmon stocks. We visited a new construction site on the Englishman River (Vancouver Island). The Englishman River utilizes side channel production for the lower river and coho salmon colonization for the inaccessible reaches. ,Spawning .and rearing channels built in 1988 use groundwater and infiltration galleries to provide water flows. In areas-not accessible to spawners, coho salmon fry obtained from a nearby hatchery were stocked. -For succeeding years, wild stocks from the Englishman River are the preferred donor stocks. 29
