Foundations for Future Restoration Actions: Cooperative Science and Monitoring Initiative - Lake Ontario, 2018
Environmental organizations from the United States and Canada have teamed up each year, as part of the Cooperative Science and Monitoring Initiative (CSMI) program, to assess conditions in one of the five Great Lakes. . Each year, the survey focuses on a series of research areas, such as phosphorus and nitrogen input and movement through the food web, phytoplankton and zooplankton populations, and...
Aquatic Native Species and Habitat Restoration: Cisco Spawning Habitat Assessment
Cisco (formerly known as Lake Herring) Coregonus artedi are native shallow water coregonines which were formerly very abundant in the Great Lakes and provided large commercial fisheries and healthy prey to native piscivores. In most areas outside of Lake Superior, cisco abundance is greatly reduced and in Lakes Ontario and Erie they are uncommon to rare.
Lake trout egg catch per unit effort (CPUE) estimates at Stony Island Reef, 2017, 2019 Lake trout egg catch per unit effort (CPUE) estimates at Stony Island Reef, 2017, 2019
This data set contains Lake Trout (Salvelinus namaycush) egg catch per unit effort (CPUE) estimates obtained from egg traps set on Stony Island Reef in Lake Ontario. These data were collected from sampling efforts in November 2017 and October-November 2019. Stony Island Reef is a cobble spawning reef located in the eastern basin of Lake Ontario and was chosen as the study site because it...

Great Lakes lake trout (Salvelinus namaycush) thiamine monitoring program annual report Great Lakes lake trout (Salvelinus namaycush) thiamine monitoring program annual report
Thiamine deficiency in lake trout (Salvelinus namaycush) eggs has been linked to early life-stage mortality in the Great Lakes from the 1960s through the 1990s, potentially affecting lake trout recruitment. In response, the U.S. Geological Survey’s Great Lakes Science Center (GLSC), Eastern Ecological Science Center (EESC), and Columbia Environmental Research Center (CERC), and the State

A comparison of stable isotopes and polychlorinated biphenyls 1 among genetic strains of Lake Ontario lake trout (Salvelinus namaycush) A comparison of stable isotopes and polychlorinated biphenyls 1 among genetic strains of Lake Ontario lake trout (Salvelinus namaycush)
This study quantified stable carbon (δ13C) and nitrogen (δ15N) isotopes, polychlorinated biphenyl (PCB) concentrations and growth rates among multiple genetic strains of Lake Ontario lake trout (Salvelinus namaycush) to evaluate the potential role of genetics in these parameters. Fish ranging in age from 1 to 31 years (n = 72) and representing nine genetic strains including wild-recruits...

Field and laboratory validation of new sampling gear to quantify coregonine egg deposition and larval emergence across spawning habitat gradients Field and laboratory validation of new sampling gear to quantify coregonine egg deposition and larval emergence across spawning habitat gradients
The influence of habitat and environmental conditions on Great Lakes coregonine reproduction is not well described, in part, because we lack sampling gears for early life stages that are effective across habitats. We designed new egg and larval emergence traps to quantify coregonine reproductive success across variable depths and substrates and tested them in laboratory and field...

Factors influencing egg thiamine concentrations of Lake Ontario lake trout: 2019–2020 Factors influencing egg thiamine concentrations of Lake Ontario lake trout: 2019–2020
In the Great Lakes region, thiamine deficiency is considered a recruitment bottleneck for lake trout Salvelinus namaycush and has been correlated with the consumption of non-native alewife Alosa pseudoharengus. While alewife, the most abundant forage fish in Lake Ontario, are the predominant prey for lake trout, they also consume benthic prey such as round goby Neogobius melanostomus...

Lake Ontario Lake Trout (Salvelinus namaycush) rehabilitation has been annually assessed with fishery independent surveys since 1983, in an effort to evaluate program benchmarks and compare observations with management objectives. These surveys provide information on the abundance, strain composition, and condition of the adult Lake Trout stock, as well as information on levels of...

Diversity in spawning habitat use among Great Lakes Cisco populations Diversity in spawning habitat use among Great Lakes Cisco populations
Cisco (Coregonus artedi) once dominated fish communities in the Laurentian Great Lakes. Restoring the abundance and distribution of this species has emerged as a management priority, yet our understanding of Cisco spawning habitat use is insufficient to characterise habitat needs for these populations and assess whether availability of suitable spawning habitat could be a constraint to...

Results of the collaborative Lake Ontario bloater restoration stocking and assessment, 2012–2020 Results of the collaborative Lake Ontario bloater restoration stocking and assessment, 2012–2020
Bloater, Coregonus hoyi, are deepwater planktivores native to the Laurentian Great Lakes and Lake Nipigon. Interpretations of commercial fishery time series suggest they were common in Lake Ontario through the early 1900s but by the 1950s were no longer captured by commercial fishers. Annual bottom trawl surveys that began in 1978 and sampled extensively across putative bloater habitat...

Balancing prey availability and predator consumption: A multispecies stock assessment for Lake Ontario Balancing prey availability and predator consumption: A multispecies stock assessment for Lake Ontario
Trophic interactions are drivers of ecosystem change and stability, yet are often excluded from fishery assessment models, despite their potential capacity to improve estimates of species dynamics and future fishery sustainability. In Lake Ontario, recreational salmonine fisheries, including Chinook salmon (Oncorhynchus tshawytscha) and lake trout (Salvelinus namaycush), depend on a...

Bioaccumulation of perfluoroalkyl substances in a Lake Ontario food web Bioaccumulation of perfluoroalkyl substances in a Lake Ontario food web
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals detected throughout the environment. To better understand the distribution of PFAS in an aquatic system (the Laurentian Great Lakes), stable isotope enrichment (δ13C and δ15N), fatty acid (FA) profiles, and PFAS were measured in various species from the Lake Ontario (LO) aquatic food web. Sampled organisms...

Evaluation of post-stocking dispersal and mortality of juvenile lake trout Salvelinus namaycush in Lake Ontario using acoustic telemetry Evaluation of post-stocking dispersal and mortality of juvenile lake trout Salvelinus namaycush in Lake Ontario using acoustic telemetry
Wild reproduction by stocked lake trout Salvelinus namaycush in Lake Ontario has yet to produce a self-sustaining population, requiring a reliance on stocking. Once released, age-1 juvenile lake trout are not typically surveyed until age-2, creating a gap in knowledge of fine-scale post-release behaviors. A method to track fine-scale movements and estimate mortality of juvenile lake...
