In 2016 and 2017, saxitoxin, a potent cyanotoxin, was detected multiple times in three regularly occurring VOYA algal blooms. This project will determine if saxitoxin and other detected toxins (anatoxin-a and microcystin) accumulate in fish from Voyageurs National Park lakes.
This project will measure concentrations of cyanotoxins in fish collected near areas impacted by toxin-producing cyantobacterial blooms in parts of Rainy and Kabetogama lakes in VOYA. Specifically, the goal is to determine if microcystin, anatoxin-a, and saxitoxin are accumulating in walleye, yellow perch, smallmouth bass, and white suckers.
To help us achieve this goal, the specific objectives are to:
