Drummond Island Lake Trout Spawning
Reproductive behavior of wild and hatchery lake trout in the Drummond Island Refuge, Lake Huron
August 2010 - January 2015
Lake trout supported a valuable fisheries in the Great Lakes until the 1950s, when overfishing and sea lamprey predation resulted in the loss of most populations. Despite consistent stocking efforts since the 1960s, restoration of these populations has been slow. The reasons are numerous, but may be related to differences in spawning behavior between hatchery and wild trout. This study uses acoustic telemetry to describe and compare the spawning behaviors of wild and hatchery lake trout adjacent to Drummond Island, Lake Huron. Tagged fish are monitored by an array of approximately 150 acoustic hydrophones during the fall spawning season. Fish behavior data will be overlaid on detailed bathymetric and substrate data and compared with environmental variables (e.g., water temperature, wind speed and direction, and wave height and direction collected within the array by a Tidas 900 weather buoy) to develop a conceptual behavioral model. Sites suspected of being spawning habitats based on telemetry data will be verified through use of divers and trapping of eggs and fry.
To compare the behaviors of spawning aggregations of wild and hatchery lake trout in terms of timing of arrival at spawning grounds, male-female aggregations, traveling over spawning areas, diel movements, and return rates to sites of previous spawning.
To describe and compare the environmental conditions associated with hatchery and wild lake trout behavior at time of spawning, specifically to determine whether differences in environmental conditions occur associated with behavioral expression.
To describe and compare the behavior of the two hatchery strains of lake trout stocked adjacent to the Drummond Island refuge to determine whether movement behaviors differ.
Our results will provide information critical to understanding how lake trout restoration efforts in the Great Lakes may be improved and to identifying management strategies for increasing the reproductive success of lake trout. Determining whether lake trout reproductive success is limited by the habitat selection and behavior of spawning hatchery-reared lake trout will focus future research on areas that are likely to lead to successful lake trout restoration.
