The numbered dots refer to sampling locations and are referenced in column C of the S1 Table. The column labeled “Sampling Station” in the table indicates which sampling locations were included within one spatial group. The column labeled “No. Fish” indicates the number of fish sampled in each spatial group. Spatial groups were used to examine correlation between sampling locations and H. sutherlandae prevalence and severity.

Results of Beverton-Holt equilibrium yield model.
(A) Yield and (C) mean weight of catch projections using the Jones modification of the Beverton-Holt equilibrium yield model as a function of fishing mortality for female yellow perch. (B) Percent loss of yield and (D) mean weight of catch as compared to no additional instantaneous annual mortality due to heterosporosis (H). Note in panels (B) and (D) H/year = 0 is not displayed, because there is zero loss of yield due to heterosporosis.
