Thirteen locations, including seven sites in Lake Huron and six sites in the St. Marys River, were surveyed with bottom trawling gear.  Thirty minutes of effort was targeted at each sampling site.

Thirty-three species were captured, including 29 species in Lake Huron and 19 species in the St. Marys River in 185 and 115 minutes of effort respectively. Bottom water temperatures ranged from 14.0°C to 21.2°C and averaged 17.4°C in Lake Huron and 15.2°C in the St. Marys River.

No new populations of invasive species were detected. Eurasian ruffe were not found at any locations, and round goby continue to persist at Lake Huron locations.  Neither ruffe nor goby have been found in the St. Marys River to date. 

Biologist Bowen coordinated survey efforts with assistance from Biologists Kowalski, Ania, and Boase.
