Abstract The Sea Lamprey Petromyzon marinus control program in the Laurentian Great Lakes is one of longest-running and most successful invasive species suppression programs world. Although several techniques are used to suppress Lamprey, relies heavily on regular application lampricide kill stream-dwelling larvae. COVID-19 pandemic disrupted from 2020 2022, which provided a unique opportunity test how populations wound counts fishes would respond. We evaluated consequences decreased effort...
Abstract Determining the movement and fate of fishes post‐stocking is challenging due to difficulty in monitoring them, particularly immediately after release. Bloater ( Coregonus hoyi ; Salmonidae ) a deepwater cisco that has been extirpated from Lake Ontario for several decades presently focus binational restoration stocking efforts; however, there limited information evaluate efficacy these efforts. The aim this study was examine initial post‐release survival, 3D movement, behaviour...
Abstract Stocking levels of Chinook salmon Oncorhynchus tshawytscha for Lake Ontario have been highly controversial since the early 1990s, largely because uncertainties about lakewide abundance and rates prey consumption. Previous estimates focused on years before 1995; then, however, ecosystem has undergone substantial changes, there is new evidence extensive natural recruitment. Presented here are alewives Alosa pseudoharengus in a reevaluation potential risk alewife population collapse....
Abstract To evaluate the species‐specific and stream‐specific suitability of juvenile salmonine habitat in southern Lake Ontario watershed, we studied effects multiple environmental gradients on first‐summer apparent survival growth various combinations Atlantic salmon Salmo salar , rainbow trout Oncorhynchus mykiss coho O. kisutch stocked tributaries. Costocking either species had no detectable effect or change cohort biomass salmon, but their rates were reduced slightly when they with...
Abstract Cisco ( Coregonus artedi ) once dominated fish communities in the Laurentian Great Lakes. Restoring abundance and distribution of this species has emerged as a management priority, yet our understanding spawning habitat use is insufficient to characterise needs for these populations assess whether availability suitable could be constraint recovery. We characterised incubating eggs situ across gradients depth substrate types describe used by three Lakes populations. In Chaumont Bay,...
Mysids are an important component of Great Lakes foodwebs, both as a prey for fish and predator on zooplankton. We monitored mysid abundance in Lake Ontario using lake-wide hydroacoustics data vertical net hauls collected 1–5 August 2008 during the Ministry Natural Resources New York State Department Conservation forage survey. Acoustic volume backscattering strength was highly correlated with density biomass mysids although correlation stronger. The slopes these relationships were not...
Trophic interactions are drivers of ecosystem change and stability, yet often excluded from fishery assessment models, despite their potential capacity to improve estimates species dynamics future sustainability. In Lake Ontario, recreational salmonine fisheries, including Chinook salmon ( Oncorhynchus tshawytscha) lake trout Salvelinus namaycush), depend on a single prey species, alewife Alosa pseudoharengus). To accommodate strong trophic among we developed multispecies statistical...
Abstract Restoration stocking of hatchery‐reared lake trout Salvelinus namaycush has occurred in Lake Ontario since 1973. In U.S. waters, fish stocked through 1990 survived well and built a large adult population. Survival yearlings from shore declined during 1990–1995, numbers fell 1998–2005. Offshore was initiated the late 1990s response to its successful mitigation predation losses double‐crested cormorants Phalacrocorax auritus results earlier studies that suggested it would enhance...
Abstract Overwinter growth of young‐of‐the‐year (age‐0) Atlantic salmon Salmo salar was studied during two winters in central New York streams. We hypothesized that longer and colder would negatively influence the age‐0 salmon. Further, we predicted survival be positively correlated with their size before winter period. Four cages were placed streams at three sites 2000 2001, six individually marked per cage. One cage retrieved monthly each site weight, length, energy density fish measured...
Abstract We determined the stocking origin of Chinook Salmon Oncorhynchus tshawytscha harvest and compared relative survival tributary returns pen‐acclimated direct‐stocked salmon at eight sites in Lake Ontario. parr were coded‐wire‐tagged 2010, 2011, 2013, adult recovered lake tributaries from 2011 to 2017. counts indicated that pen acclimation provided significantly better smolt‐to‐lake survival, with averages 1.7, 2.3, 2.3 times greater contribution (SE = 0.15, 0.21, 0.23), respectively,...
