Baltimore Early Registration Deadline Approaching

Heading to Baltimore? You'll be in good company, with more than 1,000 abstracts submitted and 80% as in-person presentations. There's only a few days left to take advantage of early registration rates - save up to $150 on in-person rates by registering by Tuesday, August 31.

Vaccination Requirement for Baltimore Meeting

AFS has instituted a Covid-19 vaccine mandate for those physically attending the AFS Baltimore meeting. This is in accordance with our fundamental policy of hosting an event that protects the health of our attendees to the greatest degree possible. Additional guidance is being developed by staff and AFS leadership and will be shared when approved. The guidance will provide allowances for those who have religious or specific health reasons to not be vaccinated but will stipulate appropriate testing requirements. AFS will also adhere to any mask mandate by the City of Baltimore and other CDC guidance at the time of the meeting. Please see the FAQ page for more information.

Meet Your Baltimore Continuing Education Instructors

"I love working with GIS, so being able to share that with others makes me happy. " Some of our Continuing Education instructors share their thoughts on why they're excited about their courses at the Baltimore Annual Meeting. Two more classes have recently been added - see the full list of courses.


The U.S. Academic Fisheries Co-Authorship Network Under the Lens of Diversity and Inclusion

The inclusion of diverse individuals in ecological sciences has shown little progress over the past 2 decades for various reasons, including structural barriers in societies, organizations, and academia. Collaboration networks are important for productivity, promotion, and scientific impact, yet the extent to which the structure of these networks affects the inclusion of minoritized people remains unknown. Here, the authors of this paper evaluated trends in published research between 1965 and 2017 within the U.S. fisheries science academic co-authorship network and evaluated its structural composition, focused on gender and race/ethnicity.

Relative Cost and Post-Release Performance of Hatchery Catchable Rainbow Trout Grown to Two Target Sizes

Catchable-sized hatchery trout have become a staple component of many fisheries management programs throughout North America. Due to their size, these trout create immediate fisheries once they are stocked, and fisheries managers have gradually shifted towards stocking fewer, larger trout. However, the cost of growing larger fish may reduce the efficiencies of catchable stocking programs overall. The authors of this paper grew catchable-sized Rainbow Trout Oncorhynchus mykiss to two target average sizes (254 and 305 mm total length) at a production scale, while tracking feed expenditures to examine the costs and benefits associated with increased size-at-stocking.


Measuring Tailbeat Frequencies of Three Fish Species from Adaptive Resolution Imaging Sonar Data

Imaging sonars, such as the Adaptive Resolution Imaging Sonar (ARIS), provide high-resolution sonar data that are used in fisheries research and management. While sonar methods have enormous potential for making population estimates, species identification via sonar remains an unresolved challenge. One method that may overcome this challenge involves measuring tailbeat frequencies to guide species differentiation. The tailbeat frequencies of three commonly sympatric anadromous fish species of eastern North America, Atlantic Salmon Salmo salar, Striped Bass Morone saxatilis, and American Shad Alosa sapidissima, were measured from imaging sonar data collected in an experimental low-flow, short-range setup.

Evaluating the Impact of Recreational Harvest and Management Strategies for Bay Scallops in a Florida Coast Management Zone

Since 1994, the fishery for bay scallops Argopecten irradians concentricus in Florida has been limited to a recreational fishery that operates during the summer, before the spawning season in fall. Recent growth of the fishery necessitates a study of the effect of this increased exploitation on the bay scallop population. The study focused on one management zone, centered on the community of Steinhatchee, that is known for high rates of exploitation. Within this zone, the authors of this paper created a model of bay scallop harvest using fishery-independent and fishery-dependent survey methods and evaluated the risk of extirpation of the stock.


Aquatic Science Societies Urge Clean Water Act Section 401 Rule Restoration

Several aquatic science societies jointly urged the Environmental Protection Agency to revise the Clean Water Act Section 401 Certification Rule to provide full state and tribal authority to promote water quality under the act.

WOTUS Comments Due September 3

AFS is urging the EPA to swiftly rescind the harmful 2020 Navigable Waters Protection Rule and quickly re-establish a durable, science-based definition of Waters of the the United States (WOTUS) that will allow the Clean Water Act to fulfill its mandate to restore and maintain the chemical, physical, and biological integrity of the nation’s waters. See our previous letter to the White House for more information.


AFS Officer Transition

Although the Annual Meeting was rescheduled until later this year, the AFS officers officially transitioned in August, with Leanne Roulson becoming AFS President. Past President Brian Murphy will still host the Baltimore meeting in November, with Roulson set to preside over the 2022 meeting in Spokane. We thank outgoing Past President Scott Bonar for his service and welcome incoming Second Vice President Miguel Garcia-Bermudez.

Best Student Paper and Poster Deadline Extension

September 1.

Call for JASM2022 Session Proposals

The Joint Aquatic Sciences Meeting (JASM) Program Committee invites proposals for symposia, pre-conference workshops and professional development courses, and integrated events which support the conference theme of "Rapid Changes ~ Collaborative Solutions." JASM2022 will bring together nine aquatic science societies in Grand Rapids, Michigan, May 14-20, 2022. Session proposals are due by September 24, 2021.
