The injurious wildlife provisions under the Lacey Act (U.S. Code, volume 18, section 42(a)(1)) are used by the U.S. Fish and Wildlife Service (USFWS) to regulate importation and movement of nonnative species in the United States. Under this act, “importation into the United States, any territory of the United States, the District of Columbia, the... Read More
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
Photo credit: National Park Service We review a 28‐year project to restore a Bull Trout Salvelinus confluentus population in a small Oregon watershed. Restoration evolved from eradication and exclusion of nonnative fishes within the boundaries of a national park to stream reconstruction and reconnection of a historical stream network across state and private property. Management of... Read More
Throughout my time serving as an officer of the American Fisheries Society (AFS), I have engaged in many discussions concerning membership. Those discussions have concerned topics such as how many members we have, why we don’t have more members, why many fisheries professionals attend Chapter meetings but do not become AFS members, and what can...

The International Pacific Halibut Commission (IPHC) is a public international organization that was established in 1923 by an agreement between Canada and the United States. Its mandate is to perform research on and manage Pacific Halibut Hippoglossus stenolepis stocks within the waters of both nations. Every year the IPHC staff conducts numerous scientific projects to... Read More
Photo credit: D. J. Orth. Social media has great, unrealized potential to improve student learning and engagement. Whereas some traditional face‐to‐face instruction may encourage “cram, pass, and forget” learning strategies, a holistic approach to student learning requires smart use of social media to facilitate long‐term personal, professional, and scholarly development. In this paper, I advocate... Read More
Photo credit: scyther5/Shutterstock Social media has revolutionized how people communicate with one another. This has important implications for science, environmental advocacy, and natural resource management, with numerous documented professional benefits for people in each of these fields. Some fisheries management professionals have been wary of social media use, in no small part due... Read More
Bayesian inference is everywhere, from one of the most recent journal articles in Transactions of the American Fisheries Society to the decision-making process you undergo when selecting a new fishing spot. Bayesian inference is the only statistical paradigm that synthesizes prior knowledge with newly collected data to facilitate a more informed decision—and it is... Read More
