Abstract
Carp culture plays an important role in inland
fisheries sector in India. Parasitism is a factor that negatively affects fish
production and ectoparasitic crustacean are the common fish parasites found in
freshwater ponds. Total 150 indigenous and exotic carps with 25 fish of each
species were collected from fresh ponds of Balrampur city. Fish sample
collected were divided into three group small (<10cm), medium (10-15cm) and
in larger length group (>15cm). Total 293 parasites were collected from
infected fishes. The number of infected fish samples was 59 out of 150. Three
crustacean ectoparasites viz., Ergasilus sp., Lernaea sp. and Argulus sp. were
collected from scales, gills, skin and base of fins of fishes. The highest
number of parasitic infections was found to be Argulus sp. (52.55%)
followed by Lernaea sp. (31.06%) and Ergasilus sp. (16.38%). The
highest abundance and mean intensity of fish parasites were observed in lowest
length group (<10cm) followed by median length group (10-15cm) and highest
length group (>10cm) of fishes in all the six species. In present
investigation the general mean intensity of infection in indigenous carp was
higher than exotic carp. Rate of infection was maximum in lowest length group
than highest, but prevalence of infection was maximum in median length group of
fishes (Except common carp) than lowest and largest groups.
