Abstract

Infection with the parasite Diplostomum sp. can lead to severe ocular pathology and may result in host mortalities in commercial fish farming.

Typical results of metacercariae occurrence in the fish eye included exophthalmia, local haemorrhage and lens cataract. There was a significant positive correlation between the body condition of fish and the parasite burden (Spearman rank correlation coefficient, R=0.625, n=100, p
