Walleye activity data from accelerometer-bearing acoustics transmitters deployed in the Great Lakes + Lake Winnipeg

It includes hourly VeDBA data for tagged fish (walleye_hourly_summary.csv), the analysis script (Bihun_ACCEL_script_revised_Sept28_2026.R), and the fitted lake-specific GAMMs and calibration coefficients (walleye_vedba_models.rds).

The models relate hourly ln VeDBA to temperature (with separate curves for each sex), ln body mass and sex, controlling for detection count, diel and seasonal variation (hour of day and day of year) and individual fish.</p><p dir="ltr">An annotated R example (walleye_energy.R) shows how to use them. Its functions predict hourly VeDBA from temperature and body mass (<i>get_vedba</i>), convert VeDBA to oxygen consumption and energy expenditure using the swim-tunnel calibration (<i>get_energy</i>), and sum hourly values to daily totals (<i>daily_totals</i>).
