Fishing planet common carp california1/19/2024 ![]() Based on our findings, common carp should be managed at a regional level, as opposed to single sites, owing to their extensive movements. ![]() Knowledge of spawning habitat could inform efforts to exclude common carp from these specific locations. ![]() Non-resident common carp tagged at TH made extensive movements in spring and summer along the nearshore of Lake Ontario and were detected throughout the entire basin. Larger individuals tagged in TH were more likely to be absent from the array during summer. All common carp tagged in HH were resident, compared to half of individuals tagged in TH. Specifically, during spring and summer common carp had significantly higher RI at sites with increased submerged aquatic vegetation, which could be associated with spawning activities. Linear mixed modelling revealed that season, as well as the interaction between season and physical habitat conditions significantly affected RI. First, Residency Index (RI), as a metric for habitat preference, was calculated for common carp in Toronto Harbour (TH) and Hamilton Harbour (HH). ![]() The aim of this study was to examine the spatial ecology of common carp across multiple spatial scales within Lake Ontario using passive acoustic telemetry. Knowledge of spatial ecology is necessary to effectively manage non-native species and aid in the development of remediation strategies. Common carp have negatively impacted freshwater ecosystems, including in the Great Lakes, by increasing turbidity and uprooting vegetation through foraging and/or spawning activities. ![]() Common carp, Cyprinus carpio, are a non-native species that established within the Laurentian Great Lakes more than a century ago and are abundant in some locations. ![]()
