Tench (Tinca tinca) were sampled between October 2002 and February 2003 in Lake Beysehir and examined for Ligula intestinalis plerocercoid infestation. Prevalence ranging from 41.66% +/- 8.33 to 84.52 +/- 1.19, decreased with increasing fish size. Index of parasitization (I-P) did not differ among the fish length classes however, monthly fluctations in I-P were significant. Minimum I-P value was recorded as 2.72 +/- 0.30 in October and maximum I-P 5.5 +/- 0.49 in February. There were no consistent trends in plerocercoid weight in relation to fish weight. Mean intensity levels did not vary in the length classes of fish. No significant differences were observed in mean intensity levels in the months studied except in February.
