Environmental and biological factors influence migratory Sea Lamprey catchability: Implications for tracking abundance in the Laurentian Great Lakes
Sea Lamprey Petromyzon marinus population trends in the Great Lakes are tracked by trapping migratory adults in tributaries and using mark and recapture techniques to estimate abundance. Understanding what environmental and biological factors influence Sea Lamprey capture in tributaries is crucial to developing efficient trapping methods and reliable abundance estimates. We analyzed data from tr

Preliminary status of Lake Ontario Alewife based on the 2019 spring trawl survey
-The 2019 spring prey fish trawl survey was the most extensive fish survey ever conducted on Lake Ontario with 252 bottom trawls collecting 214,569 fish from 39 species, in main-lake and embayment habitats, at depths ranging from 5 to 225 meters (16.5 – 742.5 feet).-Alewife distribution was similar in U.S. (southern) and Canadian (northern) portions of the lake, which differs from the previous thr

Characteristics for the external identification of Black Carp from Grass Carp
Black Carp Mylopharyngodon piceus and Grass Carp Ctenopharyngodon idella are morphologically similar species native to eastern Asia and imported to North America as biological control organisms. Preferred identification methods are coloration and pharyngeal tooth form. Grass Carp possess serrated teeth and Black Carp molariform teeth. Examination of pharyngeal teeth causes extensive damage to a sp

The future of barriers and trapping methods in the sea lamprey (Petromyzon marinus) control program in the Laurentian Great Lakes
A major duty of the Great Lakes Fishery Commission (GLFC), created in 1955, was the development a program of eradication or management of sea lamprey populations in the Great Lakes for the protection of the Great Lakes fishery. Beginning in the 1980s the GLFC shifted sea lamprey control to an integrated pest management model seeking to deploy control measures which target multiple life stages. Cur

Evaluation of potential sources of sauger Sander canadensis for reintroduction into Lake Erie
Sauger (Sander canadensis) supported recreational and commercial fisheries in Lake Erie until the fishery collapsed in the early-1950s, with extirpation of sauger occurring soon after. Previous attempts to rebuild populations via stocking programs were unsuccessful, and the reasons for lack of success are unclear. The Ohio Department of Natural Resources-Division of Wildlife is re-examining the fe

A conceptual framework for the identification and characterization of lacustrine spawning habitats for native lake charr Salvelinus namaycush
Lake charr Salvelinus namaycush are endemic to the formerly glaciated regions of North America and spawn primarily in lakes, unlike most other Salmoninae. Spawning habitats for lake charr are thought to be characterized by relatively large substrate particle sizes which provide sufficient interstitial spaces for egg incubation, but little is known about the physical processes that create or mainta

Push and pull of downstream moving juvenile sea lamprey (Petromyzon marinus) exposed to chemosensory and light cues
Visual and olfactory stimuli induce behavioural responses in fishes when applied independently, but little is known about how simultaneous exposure influences behaviour, especially in downstream migrating fishes. Here, downstream moving juvenile sea lamprey (Petromyzon marinus) were exposed to light and a conspecific chemosensory alarm cue in a flume and movement were monitored with overhead camer

Prey fish communities of the Laurentian Great Lakes: A cross-basin overview of status and trends based on bottom trawl surveys, 1978-2016
Annual bottom trawl surveys were initiated in the 1970s in Laurentian Great Lakes Superior, Huron, Michigan and Ontario and in 1990 in Erie to provide annual assessments of the status and trends of prey fish communities. Native Cisco Coregonus artedi and Bloater C. hoyi dominated the prey fish community of Lake Superior. Prey fish communities in lakes Huron and Michigan were dominated by nonnative

Restoration of Lake Trout in Lake Superior through Interagency Cooperative Management
The lake trout is a keystone species in the Laurentian Great Lakes that supported valuable fisheries throughout the basin. However, lake trout populations declined to near extirpation in nearly all of the lakes because of the combined effects of over-fishing, sea lamprey predation, and habitat degradation. To restore self-sustaining lake trout populations in Lake Superior, state, provincial, fed

Lake Ontario deepwater sculpin recovery: An unexpected outcome of ecosystem change
Fish population recoveries can result from ecosystem change in the absence of targeted restoration actions. In Lake Ontario, native Deepwater Sculpin Myoxecephalus thompsonii, were common in the late-1800s, but by the mid-1900s the species was possibly extirpated. During this period mineral nutrient inputs increased and piscivore abundance declined, which increased the abundance of the nonnative p

Trout as native and non-native species: A management paradox
Native trout are threatened worldwide by introductions of non-native trout that in many cases are themselves threatened within their native range and historical habitats. This chapter focuses on this paradox and addresses how information gained to protect and restore a species in its native range can be used to suppress the same species outside its native range, where it may be invasive. We desc

Ethical guidelines for publication of fisheries research
In 2000, the Governing Board of the American Fisheries Society (AFS) approved the first Guidelines for Authorship (GFA) in AFS publications, developed by the AFS Publications Overview Committee (POC) chaired by Mary Fabrizio. This version of the GFA document provided guidance for fisheries science publications for nearly two decades. The 2015 AFS President Donna Parish charged the POC to revise th
