Ectoparasite Trichodina on freshwater fishes at Moyog river in Babagon area, Penampang / Clodia Geofery

This aimed of this study was documented the ectoparasite (Trichodina) on freshwater fish at Moyog River in Babagon area, Penampang. The objectives were identifying distribution parasite between three stations, determine the prevalence and intensity of parasite by fish gender, and determine correlation between parasite intensity with length and weight by fish gender. The genus Trichodina found at Moyog River in Babagon area, Penampang with total number of 52. No statistical significant for distribution Trichodina between three different stations means no correlation, KW test showed x2(2) = 0.507, P= 0.776 with a mean rank Trichodina distribution of 47.40 for station 1, 45.87 for station 2, and 43.23 for station 3 when run Kruskal-Wallis test. Prevalence and intensity of Trichodina by fish gender showed that male fish had the highest prevalence (42.9%) and intensity (1.47) compared to female fish prevalence (40%) and intensity (1.36). Spearman correlation showed no relationship between Trichodina intensity with length for both male (r =0.331) and female (r = 0.014) fish. Negative correlation Trichodina intensity with weight for male fish (r = -0.022), for female fish (r = 0.093) also no statistical significant means no relationship between Trichodina intensity with weight. Strona and Fattorini (2014) stated that the number of parasite species found on host tends to be independent form the host body. Moreover, factor affecting the number of parasites per host is parasite specificity itself, not host characteristics. In future, it is recommended that the Trichodina parasite is further studied at Moyog River in Babagon Area, Penampang by doing identification up until the species level and also study on the indirect relationship of parasites with its host so there will be more useful information can be obtain.
