Assays Are Important but Not Simple to Create

By Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] Fish culturists struggle constantly with preventing and treating disease, but one helpful trend is the development of assays that can provide rapid diagnostics so that disease presence can be verified or treated. Saranya Plaon and colleagues at the Srinakharinwirot University (Thailand) present a great look... Read More

Timing is Everything during Salmon Migration in Estuaries

As an anadramous species, Atlantic Salmon Salmo salar have a complex life history that includes spending part of their lives in freshwater, estuarine, and marine habitats. In recent years, the decline of Atlantic Salmon has been attributed to their poor marine survivorship, due in large part to climate change. However, factors contributing to their marine... Read More

Avoiding Domestication of an Endangered Species: Conservation Culture of California’s Delta Smelt

Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] This article highlights efforts to conserve Delta Smelt Hypomesus transpacificus, an endangered species threatened by habitat loss and drought in the Sacramento/San Joaquin Delta. This is an important topic because several social media communications have blamed Delta Smelt for exacerbating California’s current drought issues. This has... Read More

Identifying Endocrine Disrupters as an Emerging Issue: Smallmouth Bass in the Potomac River

Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] With this article, Vicky Blazer (U.S. Geological Survey, National Fish Health Research Laboratory) and her colleagues established clearly that endocrine disruptors were a potential issue for fish health, and not just in watersheds with high human population densities. They found a surprisingly high incidence of intersex... Read More

Environmental DNA Clearinghouse: New Tools for Managers

Recent advances in genetic analysis are transforming the ways in which biologists monitor and manage aquatic organisms. Traditional monitoring techniques for aquatic species are often costly and time-intensive, especially when managers need information about rare, elusive, or newly-colonizing species. Analysis of DNA found in the environment, or eDNA, can provide managers with data about the... Read More
