Identifikasi, tingkat prevalensi dan intensitas ektoparasit pada benih ikan mas (Cyprinus carpio L) Di Balai Perbenihan dan Pengendalian Hama Penyakit Ikan (BP2HPI), Tateli

Abstract

This study aimed to determine the type of parasites, prevalence rate, and intensity of parasite infestation in carp fry (Cyprinus carpio L) in the ponds of the Fish Pest and Disease Control Center (BP2HPI), Tateli. Sampling was done randomly (random sampling) from 3 different ponds, and the number of samples for test fish was 30 samples with fish fry sizes 4-7 cm. Parasite examination was conducted at the Tateli Laboratory of the Fish Disease Pest Control and Seed Center (BP2HPI). Parasite examination in fish includes several parts, namely the body surface (fish scales), fins, and gills. Carp samples from each pond were placed in 3 different buckets filled with water and then taken to the laboratory of the Tateli Fish Disease Pest Control Center for parasite examination. Observations of the types of ectoparasites were made using a microscope and identification of the parasites using references from identification books. The data obtained were then analyzed to obtain prevalence and intensity values. The results showed that four types of parasites, Dactylogyrus sp., Gyrodactylus sp., Argulus sp., and Myxobolus sp. were identified as infecting carp fry at BP2HPI Tateli. The results of data analysis showed that the prevalence rate of parasite infestation ranged from 0.0-60% with the criteria of rarely to common (regular infection), and the intensity level of parasite infestation was 0.3-8 individuals/head with the criteria of very low to low.
