Abstract Submission for Virtual Annual Meeting Extended to June 30

We are getting close to finalizing plans for our Virtual Annual Meeting in September. The conference will include a mix of plenary sessions, engaging panel presentations, live sessions, facilitated topical discussions, and convenient on-demand recordings over two weeks, September 14-25, 2020. We anticipate more than 600 papers and 10 days of live programming. Registration rates, including discounts for students, young professionals, and retirees, are still being finalized and will be announced soon. Because some of these plans are still in flux, and also because some potential presenters have been impacted by current events, we are extending abstract submission until June 30. We expect to have more concrete information available prior to that date.


AFS Stands Against Racial Biases and Injustices

To be silent is to be complicit. The American Fisheries Society officers issued a statement of solidarity with the Black community against racial biases and injustices, and we support our colleagues, students, and friends who are impacted by these actions.

Draft World Aquatic Societies Climate Statement

The American Fisheries Society is teaming with other aquatic scientific societies worldwide to author a “Statement of World Aquatic Societies on Human-Caused Climate Change”. This statement, which will be circulated to the media, highlights major scientific findings related to effects of climate change on aquatic ecosystems, including recommended actions to avoid further degradation. We are seeking comments on this document from AFS membership by July 1, 2020. For comments on the science basis of the letter, please provide peer-reviewed reference[s] to support your recommendations.


Coronavirus, Climate Change, and a Bit of Hope

Inspired and hopeful! Those words describe how I feel after seeing the worldwide and AFS member response to coronavirus. The pandemic is of course devastating, but some good things are collateral results of a world shifting gears. The kindness, hard work, and decency of people, including fisheries professionals, are on full display.

Hiding in Plain Sight: Historical Fish Collections Aid Contemporary Parasite Research

Natural history collections provide a wealth of information beyond the scope of their initial purpose, including a historical window into host–parasite relationships. For example, collections can reveal historical infections of fishes by the freshwater gill‐maggot Salmincola californiensis, a parasite of increasing concern because of negative effects on salmonids in large western reservoirs.


Genetic Structure of Smallmouth Bass in the Lake Michigan and Upper Mississippi River Drainages Relates to Habitat, Distance, and Drainage Boundaries

Analysis of genetic connectivity helps to define stock boundaries and provides information on inter-population dynamics such as migration and spawning site fidelity. The authors use 16 microsatellite loci to describe the genetic population structure of 1,215 Smallmouth Bass Micropterus dolomieu from 32 sites throughout the Upper Mississippi River and Lake Michigan watersheds.

Morphological Variation of Cisco across Gradients of Lake Productivity

The effects of lake productivity and late‐summer hypolimnetic oxygen on the size and shape of Cisco Coregonus artedi were examined in 27 Minnesota lakes. Geometric morphometry analyses of specimens captured in vertical gill nets indicated that Cisco in more productive lakes with hypoxic hypolimnia were larger, with deeper bodies, shorter snouts and caudal peduncles, and longer fins. Cisco in unproductive lakes with oxygenated hypolimnia were smaller, with slender bodies, longer snouts and caudal peduncles, and shorter fins. The availability of late‐summer habitat, depth‐mediated predation risk, and growth potential appear to be important ecological drivers of morphological variation in Cisco.
