Acoustic detection and biological data for Lake Trout, Salvelinus namaycush, in Lake Ontario

Acoustic Telemetry is gaining popularity for use in fisheries research as a method to estimate survival and observe behaviors of native fish species. Methodology for capture and tagging of fish is typically context and species-specific, requiring a case by case basis for best practices to maximize survival of tagged individuals. This dataset includes acoustic detection data from 320 adult Lake Trout, Salvelinus namaycush, captured and acoustic-tagged in Lake Ontario during April-June of 2023. Biological data (total length), capture data (surface water temperature, capture depth), capture location, and capture gear (angling, bottom trawls, gillnets) are also included in the dataset as covariates that can be analyzed to determine if any of these factors affect post-release survival of tagged Lake Trout. Acoustic detection data is available from April 2023 to November 2024. Survival of acoustic-tagged Lake Trout was estimated through acoustic telemetry detections indicating the status of the Lake Trout (alive vs. dead).
