Frequency of ectoparasite infestation Siamese fighting fish (Betta splendens) in Qom province in Iran

Abstract

In summer of 2018, number of 100 Siamese fighting fish (Betta splendens) were sampled randomly and transferred with their own water with
aerated bags to ornamental fish clinic of Faculty of veterinary medicine of University of Tehran. Then wet mount from skin and gills of the
fish were prepared and were examined with a e600 microscope. In total, the prevalence of parasitic infections in skin and gill was 37%. 9 were
infected with Ichthyophthirius multifiliis (9%) and 28 were infected with Piscinoodinium (28%). No fish were infected with other ectoparasites.
For treatment of the fish infected with Ichthyophthirius multifiliis fish were submerged in water with 2% NaCl for an hour and then their water
was gradually (in 10 days) heated up to 31ºC. For treatment of the fish infected with Piscinoodinium we only heated the water up to 31ºC in 10
days and kept the fish in darkness. After 2 weeks fish were sampled from their skins and gills and no infestation were observed.
