PREVALENSI TRICHODINA PADA KONDISI LINGKUNGAN PERAIRAN BERBEDA
ABSTRACT: Investigation on the
occurence of Trichodina on Fish Culture Center (FCC) in Banyumas Residence. This
study was conducted in order to know the correlation between occurene
(prevalence and intensity) of Trichodina with organic material and the number
of total bacteria in the water. Samples of mucus that observed under microscop
were collected from skin and exterior hemibranchia of 90 specimen of fishes
that collected from three FCC. Samples of water quality, organic material and
the number of total of bacteria in the water were taken from inlet, outlet and
at the middle of Fish Culture Center. Samples of fishes collected from
Tambaksogra FCC revealed a lower prevalence (76,67%) and from Pandak FCC was
the higher (93,33%). Enviromental changes, exspecially alkalinity found tohave
a strong influence to prevalence Trichodina, but the intensity influenced by
dissolve oksigen. The number of total bacteria and organic material in the
water that expressed a biological indicator was also found to have influenced
the prevalence and intensity of Trichodina.This mean that Trichodina was being
applicable as biological indicator of aquaculture.
