Au Sable River Juvenile Steelhead
Use of predation tags to evaluate mortality of stocked hatchery steelhead smolts
April 2023 - December 2023
This project will investigate the use of predation tags to estimate mortality of stocked steelhead smolts in the Au Sable River, Lake Huron. This is a pilot study to determine if the steelhead smolts will suitably accept implantation of the smallest currently available 69 kHz predation tag and to determine if the receiver grid currently deployed in Lake Huron will provide adequate spatial and temporal resolution to accurate estimate predation mortality on these fish.
