Estimation of the Effective Number of Breeders for Warm Springs River Spring Chinook Salmon - Broodyears 2015 and 2016
Spring Chinook Salmon spawning in the upper Warm Springs River basin have demonstrated a relatively sudden increase in the ratio of annual adult escapement to total redd count. Prior to 2010 the ratio averaged 4 fish per redd, but since then the average jumped to 12 fish per redd. The recent high...

Kelt Reconditioning: A Research Project to Enhance Iteroparity in Columbia Basin Steelhead (Oncorhynchus mykiss) - 2003 Annual Report
Repeat spawning is a life history strategy that is expressed by some species from the family Salmonidae. Rates of repeat spawning for post-development Columbia River steelhead Oncorhynchus mykiss populations range from 1.6 to 17%. It is expected that currently observed iteroparity rates for...

Reproductive Performance and Energy Balance in Consecutive and Skip Repeat Spawning Female Steelhead Reconditioned in Captivity
Steelhead Oncorhynchus mykiss are known for their life history diversity, displaying a range of freshwater residence ages, maturation ages, and spawning intervals. Female maturation is thought to be condition dependent at critical periods, during which individuals falling below energetic...
