Lake trout (Salvelinus namaycush) egg density estimates in Lake Ontario from egg pumping, 2020, 2024
This data set contains Lake Trout (Salvelinus namaycush) egg density estimates obtained from suction sampling across five locations in Lake Ontario. These data were collected in October-November 2020 and November-December 2024 as part of an effort to identify Lake Trout spawning locations and habitat preference in Lake Ontario. Additional information on habitat characteristics at each sampling site was collected using an underwater camera and was classified using the Coastal and Marine Ecological Classification Standard (CMECS). The two files in this data set include a comma delimited machine-readable file (*.csv) containing the Lake Trout egg density estimates and substrate classification data, and an XML file containing the metadata information.
