Abstract: A survey was undertaken to study the size and weight of fish hosts in relation to prevalence and intensity of parasites to determine the morphological constraints and other predicators that may influence their interactions. The guts of freshly caught fish were dissected in clean dissecting trays and the contents washed into petridishes using 4% formaldehyde for examination of helminth parasites under a dissecting microscope. The highest prevalence in the small sized group was 34.9% in respect Of Neoechinorhynchus sp.1 infection and 0.2% for Clinostomum tilapia and Camallanus sp.1 infection the least (0.0%). Among the big fish groups, the highest prevalence was 31.1% for Neoechinorhynchus sp.1 infection and the least 0.2% for Proteocephalus sp. Infection. The total mean abundance for small fish was 7.29 and 9.80 for big fish group.
