Abstract Determining which factors are most effective for mitigative strategies in conservation management can be difficult for species with complex life cycles. Salmon (Oncorhynchus spp.) migrating through a hydroelectric power system experience con

Allocating reservoir flows to meet societal and ecosystem needs under increasing demands for water and increasing climatic variability presents challenges to resource managers. Often, regulated rivers have been operated to meet flow and temperature c

The nonlinear relationship of egg development rates to temperature due to compensatory mechanisms in Chinook Salmon Oncorhynchus tshawytscha, has consequences for emergence timing in nonoptimal and/or highly variable temperature regimes. A mechanisti

We projected effects of mid-21st century climate on the early life growth of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) in western United States streams. Air temperature and snowpack trends projected from observed 20th centur

Migrating salmonids often return to their spawning habitats in overlapping timing patterns of multiple stocks (populations) collectively called a run that varies in its genetic makeup across and within years. Managers, tasked with developing harvest

A mechanistic temperature-dependent model for preemergent growth coupled with spawning and river temperature data is used to evaluate early life history strategies for chinook salmon (Oncorhynchus tshawytscha) in the Methow River, Washington, U.S.A.

Embryo and alevin development in chinook salmon Oncorhynchus tshawytscha were analyzed with mechanistic and empirical models. Output from a mechanistic model (model BA) based on differential equations that generates a trajectory of embryo, alevin, an

A mechanistic model for the growth of salmonid embryos (prior to feeding) is developed with coupled differential equations describing anabolism and catabolism. The equations model changes in embryo and yolk sac masses in which the flux of nutrients t
Columbia Basin Research uses the COMPASS model on a daily basis during the outmigration of Snake River Chinook and steelhead smolts to predict downstream passage and survival. Fish arrival predictions and observations from program RealTime along with
