Accumulation of cyanobacteria toxins in Lake Erie fishes

The Lake Erie ecosystem is once again experiencing nutrient pollution, which has increased the occurrence of harmful algal blooms and outbreaks of cyanobacteria that produce the liver toxin, microcystin. We are assessing whether microcystin accumulates in the edible tissues of fish. Our results will inform state agencies in the development of consumption guidelines for walleye and yellow perch from Lake Erie.
