User‐friendly stream temperature models populated with on‐site data may help in developing strategies to manage temperatures of individual stream reaches that are subject to climate change. We used the field‐tested Stream Segment Temperature model (U.S. Geological Survey) to simulate how altering discharge, groundwater input, channel wetted width, and shade prevents the temperatures of White Mountain, Arizona, stream reaches from exceeding the thermal tolerance of Apache Trout Oncorhynchus apache, both under existing conditions and under a climate change scenario…Read more

This special issue of Fisheries is not so much intended to provide information as it is to provoke thought, stimulate awareness, reflection, and in its ultimate aim, to generate conversation and action. These are the voices of your colleagues: scientists, managers, educators, young professionals, seasoned experts. This issue is deliberately not the science voice of your colleagues. They are the voices of who your colleagues are; as people who come to their work from many different perspectives, ideas, cultures, and values. These characteristics are the foundation upon which they do the work they do. Read here with free access through October 6th

As part of the Snake River Sockeye Salmon Oncorhynchus nerka recovery effort, a dedicated smolt rearing facility was constructed in 2013 near Springfield, Idaho. In‐hatchery performance and survival were typical for the species, but unexpectedly high mortality rates were observed in the first cohorts of Springfield‐reared smolts upon release into Redfish Lake Creek (RFLC) and during out‐migration. In response, a series of iterative experiments was conducted to identify the cause of the morbidity and mortality observed and to test a range of strategies to mitigate effects on postrelease survival. In the search for possible contributing factors, a difference in water chemistry was noted…Read more

Like many fish species, Rio Grande Cutthroat Trout will face additional challenges in a warming future. We explored the consequences of the wide variety of factors thought to influence persistence of the 121 remaining populations to 2080. Although streams are predicted to warm, less than 10% of populations will be affected. In contrast, nearly 65% are predicted to be extirpated (or nearly so) by nonnative trout that have already invaded or are expected to soon. Many populations will require the help of managers if they are to persist well into the 21st century…Read more

We investigated associations of fish assemblages and habitat characteristics (e.g., morphology and water chemistry) from 45 natural lakes and reservoirs in Iowa to determine whether species or trophic guild composition and environmental correlations were concordant between waterbodies of different origins. Overall, fish assemblage composition between natural lakes and reservoirs was consistently dissimilar based on a permutational multivariate ANOVA….Read more
