Evaluating How Changing Climate and Water Clarity Can Affect Restoration of Native Coregonine Fish in Midwestern Lakes
Coregonines are a sub-family of freshwater fishes within the well-known Salmonidae family. In the upper midwestern U.S., these fishes have provided a key food source to Native Americans for millennia. Since the mid-20th century, however, their diversity and abundance has declined owing to several anthropogenic stressors including overfishing, declining quality of key habitat (e.g., dams

Yellow perch (Perca flavescens) external tagging experiment data Yellow perch (Perca flavescens) external tagging experiment data
This dataset includes information from a yellow perch (Perca flavescens) tagging experiment, where the goal was to evaluate tag retention rates, and impact of tagging on growth, condition, and survival. Fish were held in a recirculating aquaculture system (RAS) over a 168-day period to evaluate four external tag types including loop, ring, streamer, and T-bar anchor tags. Data were...

Competition between invasive round goby and native slimy sculpin in a coldwater laboratory setting Competition between invasive round goby and native slimy sculpin in a coldwater laboratory setting
Slimy sculpin (Cottus cognatus) abundance has substantially declined in many regions of the Laurentian Great Lakes coincident with the arrival and range expansions of invasive round goby (Neogobius melanostomus). Previous studies have shown that round goby can outcompete native mottled sculpin (C. bairdii) for shelter and negatively affect native spoonhead sculpin (C. ricei) growth, but...

A post-restoration evaluation of fish spawning on Coreyon Reef in Saginaw Bay, Lake Huron A post-restoration evaluation of fish spawning on Coreyon Reef in Saginaw Bay, Lake Huron
Habitat diversity is important to fisheries for promoting resiliency to interannual environmental variation. Historical land use change resulting in increased sedimentation has impaired fish rock reef habitats in Saginaw Bay, Lake Huron. Pursuant to the recovery of Saginaw Bay’s walleye population, and to benefit other species, came the decision to restore the offshore habitat Coreyon...

Deconstructing cardiovascular and coagulation-related traits links dietary ecology to multi-functional snake venom specificity Deconstructing cardiovascular and coagulation-related traits links dietary ecology to multi-functional snake venom specificity
Animal venoms vary greatly in compositional complexity, where complex venoms are hypothesized to be maintained by greater dietary breadth. Beyond explaining venom composition, the dietary breadth hypothesis predicts that these more complex venoms should show greater functional breadth in terms of overall toxicity and by disrupting multiple prey physiological processes. We evaluate these

Exposure to ultraviolet radiation induces escape hatching of Cisco (Coregonus artedi) embryos Exposure to ultraviolet radiation induces escape hatching of Cisco (Coregonus artedi) embryos
Cisco (Otoonapii in Ojibwe; Coregonus artedi Lesueur, 1818), is a widely distributed stenothermic freshwater fish whose embryos typically incubate under ice and in the dark. We used Cisco as a model organism for testing the potential of UV-induced escape hatching behaviour. Owing to reduced ice cover and increased water transparency in north temperate lakes, these experiments provide...

The cisco Coregonus artedi is a coldwater fish that is distributed throughout much of Canada and the northern United States, including the Laurentian Great Lakes. Cisco historically supported large commercial fisheries in the Great Lakes during the late 1800s and early 1900s, but many populations declined and never recovered.
