Spatial distribution of monogeneans and their prevalence in two freshwater fish species in relation to some physico-chemical parameters of Kenyir Lake Malaysia. pp. 179-185. ISSN 1823-8556
Abstract
A parasitological investigation was carried out on two freshwater fish species-Hampala macrolepidota and Hemibargrus nemurus (n460) for gill monogeneans from four stations in Kenyir Lake station I-Kiang River (5649.47� N 1024436.60� E); station II-Petang Island (4658 35.65�N 102473.74� E) station III “Ketiar River (5348.38� N 1023414.70� E) and station IV-Tanjung Mentong (44836.54� N 1024540.56� E). Four monogenean parasites were detected viz: ifurcohaptor baungi and Cornudiscoides malayensis from the gills of Hemibargrus nemurus; Dactylogyrus quadribrachiatus and d. macrolepodoti from gills of Hampala macrolepidota. Their spatial distributions on the host gills are reported. The prevalences of these parasites were correlated to physic-chemical parameters (temperature dissolved oxygen pH ammonia nitrite and alkalinity) of the lake water. The results revealed that all the stations were infected but the highest infestation was in the third station (ketiar River) with 100 prevalence and intensity of 43 individual worms per host. Correlation between physic-chemical parameters and parasites prevalence shows statistical significance (P 0.05) especially between prevalence mean intensity and total ammonia nitrogen (TAN). In conclusion monogeneans from these two fish species were nor randomly distributed but showed site specificity.
