Evaluating Coho Salmon in Streams Across an Urbanization Gradient—Part 1, Growth Potential Based on Environmental Factors and Bioenergetics

Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch), extensively utilize small stream habitats influenced by a changing urban landscape. This study used a comprehensive fish health assessment concurrent with the U.S. Geological Survey’s Pacific Northwest Stream Quality Assessment in 2015 to quantifiy impacts from disease in juvenile coho and cutthroat salmon, impacts to...

Spatio-temporal variability in movement, age, and growth of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry

Connectivity of river networks and the movements among habitats can be critical for the life history of many fish species, and understanding of the patterns of movement is central to managing populations, communities, and the landscapes they use. We combined passive integrated transponder tagging over 4 years and strontium isotopes in otoliths to demonstrate that 25% of the mountain whitefish (Prosopium williamsoni) sampled moved between the Methow and Columbia rivers, Washington, USA. Seasonal migrations downstream from the Methow River to the Columbia River to overwinter occurred in autumn and upstream movements in the spring. We observed migration was common during the first year of life, with migrants being...
