Survival of juvenile steelhead in the ocean has recently been considered a possible factor in the decline of these fish but to date, long-term survival and abundance trends among Pacific Northwest populations were largely unknown. Now, using multiple decades of data for 48 populations of wild and hatchery steelhead trout, scientists at the Washington Department of Fish and Wildlife have shown that declining survival of juvenile steelhead in the ocean is strongly coupled with significant declines in the abundance of adults.
