The article focuses on the return of the Columbia River salmon at the Bonneville Dam in Washington. It says that 13 species of salmon and steelhead are considered endangered, in which close to 85% of the returning fish are hatchery fish. It mentions that genetic information has been used by researchers to better manage fish stocks.

    Although conservation groups and fishing industries alike have relied on salmon hatcheries to slow the dramatic decline in salmon and steelhead species since the nineteenth century, the proper place of hatchery-raised salmon under the Endangered Species Act remains uncertain. When the hatchery...

    The proportion of wild fish in 12 mixed populations of hatchery and wild steelhead (Oncorhynchus mykiss) was evaluated for its relationship to mean and intrinsic measures of population productivity. The population mean of ln(recruits/spawner) was used to represent mean productivity. Intrinsic...

    We compared the diet of hatchery-reared steelhead produced from an integrated hatchery program as emigrating spring smolts and non-migrating hatchery residuals to their sympatric wild counterparts. Our results suggest that there is a potential for hatchery fish to affect wild steelhead...

    Stable isotope analysis of diet switching by fishes often is hampered by slow turnover rates of the tissues analyzed (usually muscle or fins). We examined epidermal mucus as a potentially faster turnover “tissue” that might provide a more rapid assessment of diet switching. In a...
