Flannelmouth Sucker: The Ironhorse of the Colorado River Basin

When I began graduate school in 2012 at Kansas State University, I was excited to work with the highly endemic fishes of the Colorado River basin, particularly federally endangered Colorado Pikeminnow Ptychocheilus lucius. However, low catch rates combined with limited historical catch data for Colorado Pikeminnow shifted my research focus toward community‐wide investigations of native and... Read More

FishGen.net: An Online Genetic Repository for Salmon and Steelhead Genetic Baselines

FishGen is a final repository for Pacific salmon Oncorhynchus spp. and steelhead O. mykissgenetic data generated as part of the genetic stock identification and parentage‐based tagging projects in the Columbia River basin and throughout the Pacific Coast of North America. Resource Data, Inc., developed this web‐based, GIS‐interfaced software, which is freely available to the public, with funding from... Read More

A Practitioner’s Perspective on the Continuing Technical Merits of PHABSIM

Since its initial development and application in the mid‐1970s, the Physical Habitat Simulation System (PHABSIM) and models, which are part of the instream flow incremental methodology (IFIM) developed by the U.S. Fish and Wildlife Service (Bovee and Milhous 1978; Bovee 1982), has been extensively used (Reiser et al. 1989; Hatfield and Bruce 2000; Locke et al. 2008), reviewed (e.g., Wesche and Rechard 1980;...

Why Keep Hatcheries? Weighing the Economic Cost and Value of Fish Production for Public Use and Public Trust Purposes

Resource allocation for fisheries management and conservation in the United States has not grown substantially in recent years, and there is ongoing debate over how limited resources should be used to create, maintain, or restore fisheries. Hatcheries have been in existence in North America since 1848, but their organization and role in fisheries management are... Read More

Young Professional Survey Results: Member and Nonmember Perspectives on Decisions to Join the American Fisheries Society

The American Fisheries Society (AFS) recently extended the eligibility period for the young professional membership category from 3 years to 5 years post‐graduation based on a recommendation from a committee formed by the Fisheries Management and Education sections. The basis of this recommendation grew out of a survey conducted with fisheries professionals from across North... Read More

Three Visualization Approaches for Communicating and Exploring Passive Integrated Transponder Tag Data

As the number, size, and complexity of ecological data sets have increased, narrative and interactive raw data visualizations have emerged as important tools for exploring and understanding these large data sets. As a demonstration, we developed three visualizations to communicate and explore passive integrated transponder tag data from two long‐term field studies. We created three... Read More

Reclaiming a Space for Diadromous Fish in the Public Psyche and Sense of Place

Diadromous species historically dominated the freshwater fish community in coastal northeastern United States rivers. As these fishes declined in concert with sweeping alterations to the region’s waterscapes, so too did their utility, visibility, and relevance to each passing human generation. Due to their historically iconic status, we used endangered Atlantic Salmon Salmo salar as a springboard in... Read More

Evaluating the Conservation Potential of Tributaries for Native Fishes in the Upper Colorado River Basin

Photo credit: U.S. Geological Survey We explored the conservation potential of tributaries in the upper Colorado River basin by modeling native fish species richness as a function of river discharge, temperature, barrier‐free length, and distance to nearest free‐flowing main‐stem section. We investigated a historic period prior to large‐scale water development and a contemporary period. In... Read More
