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

Solutions to California’s Drought Issues: Modeling Suggests Ways to Conserve Chinook Salmon in the Face of Water Diversion

Chinook Salmon Oncorhynchus tshawytscha smolts emigrating the Sacramento River in California must navigate through a delta complex with water diversions that confer lower survival for entrained fish that leave the river. Russell Perry of the U.S. Geological Survey, Western Fisheries Research Center, and his colleagues fit an entrainment model to telemetry data and found that... Read More

Probiotics Show Promise for Aquaculture

Television viewers are now being carpet-bombed with advertising for probiotics that are alleged to improve human health via promotion of beneficial gut bacteria. But probiotics may play a real role in aquaculture where ZhiPing Yang (Dalian Huixin Titanium Equipment Development Company) and colleagues fed live yeast to cultured sea cucumbers and later challenged them to...

Using a Video Lander to Assess Difficult Marine Habitats

Deep temperate marine zones are known to support significant biological production, but they are difficult to sample because they are too deep for SCUBA and too complex for traditional nets. Ryan Easton of Oregon State University and his other colleagues found a way to do it that is not only feasible but quantitative. This journal... Read More

Bluegill Can Be Managed More Effectively with Bag Limits!

Many inland fisheries historically have allowed unlimited harvest of panfish, or have extremely liberal bag limits. The management paradigm is that fishing mortality is usually low and high harvests benefit angling by improving growth and preventing stunting. However, a new study by Andew Rypel of the Wisconsin Department of Natural Resources, Bureau of Science Services,... Read More

Coping with Crisis: Lessons from the Maine Lobster Fishery

How fisheries respond to crisis is, unfortunately, a topic of ever growing importance. Anna Henry and Teresa Johnson (School of Marine Sciences, University of Maine) used a people ecology approach to examine how fishers responded to three recent changes in the Maine lobster Homarus americanus fishery, and the reasons why those responses may have been...
