Abstract :
The present studywas carried out to survey ectoparasit
fauna of gold fish (Carassius auratus) in north
of Iran (Mazandaran province). A total of 200 samples
were obtained from 10 ornamental fish supply
centers and transferred alive to the laboratory. In
this study, the following ectoparasites were isolated:
Ichthyophthirius multifillis, Trichodina spp., Gyrodactylus
spp., Dactylogyrus vastator, Dactylogyrus
baueri and Argulus coregoni. The results revealed
that 28.5% of sampled goldfish were infested with
ectoparasites. The frequency of protozoan infestations
were 15% (9% I. multifillis and 6% Trichodina
spp.), the frequency of monogeneanectoparasite
was 12.5% (5% Gyrodactylus spp., 5% D.vastator
and 2.5% D.baueri) and that of crustaceans (A.coregoni)
was 1%. The most frequently reported infestation
was due to I. multifillis causative agent of white
spot disease. Enhancing the health management
through improving water quality and bio-security is
the most effective way to prevent the parasite infestations.
