2004-2006 US LOA Chinook Draft Report: Fixes or Alternatives to the Individual Stock Based Management (ISBM) Provisions
This report covers alternatives to the current approach used to generate Individual Stock Based Management (ISBM) indices. As shown by Sharma (2005), there are numerous problems with the current index. These stem from the fact that the model and coded-wire tagged (CWT) based indices do not track...

2005 Annual Report: An Evaluation of the Reproductive Success of Natural-origin, Hatchery-origin, and Kelt Steelhead in the Columbia Basin
We initiated a field study to investigate the relative reproductive success of artificially reconditioned kelt steelhead. Prior to an implementation of a large-scale steelhead kelt reconditioning program, it is important to evaluate the reproductive success of reconditioned kelts relative to...

2007 Annual Report: Steelhead Kelt Reconditioning and Reproductive Success
Iteroparity, the ability to repeat spawn, is a natural life history strategy that is expressed by some species from the family Salmonidae. Current rates of observed steelhead iteroparity rates in the Columbia River Basin are severely depressed due to anthropogenic development, operation of the...

2009 Annual Report: Genetic Assessment of Columbia River Stocks
This project combines four inter-related studies from the Fish & Wildlife Program Accords that address these current and future objectives: 1) discover and evaluate SNP markers in salmon and steelhead; 2) expand and create genetic baselines for multiple species (Chinook, steelhead, sockeye, and...

2009 Annual Report: Steelhead Kelt Reconditioning and Reproductive Success
Iteroparity, the ability to repeat spawn, is a natural life history strategy expressed by some species from the family Salmonidae. Observed iteroparity rates for steelhead Oncorhynchus mykiss in the Columbia River Basin are currently depressed due to anthropogenic development including operation of...

2009 Spring Chinook Escapement to the Upper Basin of the Klickitat River Based on DIDSON Sonar Counts
A Dual-Frequency Identification Sonar (DIDSON) sonar was deployed to observe fish passage through the Castile Falls Fishway on the Klickitat River, and to obtain an estimate of spring Chinook escapement to the upper basin. The DIDSON continuously recorded sequential 1-hour files from late May until...
