Abstract:
The present study was conducted to identify and
determine the prevalence and intensity of infestation
brought about by the endoparasites in Channa punctatus
(Bloch,1793) from different water bodies of varying water
quality in Bangladesh. The prevalence of endoparasites
in the host fish Channa punctatus was 91.30% in female
and 88.88% in male fishes, among them in sewage water
fishes the prevalence was 85.71% in female and 86.66%
in male and in fishes collected from a hatchery the
prevalence was 100% in both the male and female fishes.
The intensities of infestation in Channa punctatus was
6.78 in female and 6.55 in male fish collected from
hatchery; and in sewage water fishes the intensity was
3.50 in females and 1.15 in males respectively. Six
parasite species were found from polluted water fishes
and seven species of parasites were recorded from fresh
water fishes. The intensity and the prevalence were
higher in host fishes collected from hatchery than the
sewage water host fishes.
