Abstract :
The present study investigated the effects of first record of co-infection of three Clinostomum sp.; Clinostomum Complanatum
(Rudolphi, 1819), C. tilapiae (Ukoli, 1966), and Euclinostomum hetereostomum (1809) in Tilapia zilii. There was
differential parasitic effects resulting in selection for relatively better adaptiveness to host’s microhabitats, more population
size, and frequent host location of these parasites during the one year survey (Nov 2007– Oct 2008) in Opi
Lake, Nigeria. Prevalence of 9.4 % was recorded in C. complanatum, 10.4 % in E. heterostomum and 4.8% in C. tilapiae.
The parasites were recovered from three major microhabitats of buccal cavity, skin and eye.
