Abstract

Odds ratio analysis was used to evaluate the relative likelihood of occurrence of blackspot (Neascus pyriformil, Chandler) infections among 14 species of fish collected from the Maple River in Buena Vista and Ida Counties in western Iowa. Prevalence estimates ranged from 0% to 47.4% with a mean prevalence of 11.9%. The rank ordering of odds ratios of infection allowed the species to be categorized as those with risks greater than, less than, and not different from average risk to infection within the Maple River sample. The species with the largest odds ratio was the bluntnose minnow, (Pimephales notatus) (odds ratio = 7.78), whereas bigmouth shiners (Notropis dorsalis) and sand shiners (Notropis stramineus) had statistically significant odds ratios of zero.
