INTENSITY AND PREVALENCE OF ECTOPARASITES IN TILAPIA (OREOCHROMIS NILOTICUS) SEEDS INFECTED WITH ECTOPARASITES THROUGH IMMERSION OF BINAHONG LEAF BOILED WATER (ANREDERA CORDIFOLIA)

Ectoparasite is one of the causes of disease in freshwater fish, which often causes losses and freshwater fish farming failures. This study aims to determine the intensity and prevalence of ectoparasites in tilapia (Oreochromis niloticus) seeds through Binahong leaf (Anredera cordifolia) boiled water. The research method is an experimental method using a completely randomized design (CRD). The treatment was the long immersion of the binahong (Anredera cordifolia) leaf stew which consisted of four treatments, namelytreatment A (control / without immersion), B (5 minutes), C (10 minutes) and D (15 minutes) with three repetitions. Data analysis performed using RAL. In this study, two types of ectoparasites fund to infect tilapia seeds, namely Cichlidogyrus sp and Trichodina sp. The results showed that the duration of immersion affected the intensity and prevalence of ectoparasites in infected tilapia (Oreochromis niloticus) fry. The best immersion time obtained in this study on the ectoparasite intensity of Cichlidogyrus sp and Trichodina sp is treatment B with immersion time of five minutes.
