Changes in numbers and growth of Ligula intestinalis in the spottail shiner (Notropis hudsonius), and their roles in transmission

Academic Article

Abstract

  • Eighteen species of fishes were collected from Dauphin Lake, Manitoba, and examined for plerocercoids of Ligula intestinalis. Plerocercoids were most prevalent (5.3%) in spottail shiners. Number of plerocercoids differed between years and among habitats but there was no statistically significant seasonal pattern; recruitment of new worms was highest in young fish and decreased with age, and infected spottails had reduced gonad development. Infected spottails appear to be subjected to size-selective mortality. -from Authors
