| Impact ID | 8509 |
| Impact Type | Predation/Herbivory |
| Study Type | Anecdotal |
| Study Location | N/A |
| Impact Description | Declines in the Great Lakes yellow perch (Perca flavensis) stocks are believed to stress predator-prey relationships. There is no evidence to show Heterosporis sutherlandae causes fish mortality directly, but the destruction of muscle in infected fish increases susceptibility to predation. |
