PREVALENSI DAN INTENSITAS EKTOPARASIT PADA INSANG IKAN NILA MERAH (OREOCHROMIS SP.) DI KERAMBA APUNG SUNGAI KAPUAS DESA KAPUR KABUPATEN KUBU RAYA
ABSTRACT: Red tilapia
(Oreochromis sp.) are cultured in floating cages of the Kapuas River in Kapur
Village can be infected with ectoparasites, especially on the gills. This study
aims to determine the types, prevalence and intensity of ectoparasites on the
gills of red tilapia in floating cages of the Kapuas River in Kapur Village of
Kubu Raya Regency. The samples were taken in April 2016 by random sampling
method. The fish as many as 100 individuals were taken randomly from the
floating cages in five locations. Ectoparasites were found consisting of two
types which are members of the Class Monogenea, namely Dactylogyrus sp. and
Gyrodactylus sp. The ectoparasite Dactylogyrus sp. mostly infected the red
tilapia gills with the value of the average prevalence of 90% (infection
category of almost always) and the value of the average intensity of 3.97
ind/individual. The Gyrodactylus sp. found on the gills had a value of the
average prevalence of 49% (infection category of commonly) and the average
intensity value of 1.76 ind/individual.
