Columbia River Basin Steelhead Kelt Reconditioning Research

Every spring, large numbers of post-spawning steelhead kelts migrate downstream throughout the Columbia River Basin (CRB), but few return as repeat spawners. Reconditioning of female kelts is being implemented as a recovery measure for ESA-listed CRB steelhead stocks. Downstream migrating kelts are...

Post-spawning Life History Diversity in Reconditioned Female Clearwater River Steelhead Trout (Oncorhynchus mykiss) Kelts Assessed Using Plasma Estradiol-17β

Steelhead trout (Oncorhynchus mykiss) are an important anadromous salmonid of conservation concern in Idaho’s Clearwater River, where populations are in decline. Post-spawn female steelhead trout (kelts) are reconditioned as a recovery tool in the Columbia River Basin. Reconditioning...

Deep Ancestry of Programmed Genome Rearrangement in Lampreys

In most multicellular organisms, the structure and content of the genome is rigorously maintained over the course of development. However, some species have evolved genome biologies that permit, or require, developmentally regulated changes in the physical structure and content of the genome...

Sea-to-sea Survival of Late-run Adult Steelhead (Oncorhynchus mykiss) from the Columbia and Snake Rivers

We used biotelemetry and genetic stock identification to assess sea-to-sea survival and run composition of 1212 late-migrating adult steelhead (anadromous Oncorhynchus mykiss) through the Columbia River and Snake River migratory corridors. The late-run was predominated by steelhead from...
