Relationships between abundance of Ichthyocotylurus variegatus and I. pileatus in three age cohorts of perch, 0+ (A) n = 103, 1+ (B) n = 120 and 2+ (C) n = 159. Solid lines represent linear regressions indicating the direction of the relationship. Dashed lines in each panel indicate 10% of the fish individuals most heavily infected with I. variegatus (horizontal line) and 10% most heavily infected with I. pileatus (vertical line).
