The effects of formalin and sodium chloride on ectoparasites of imported grass carp (Ctenopharyngodon idella Cuvier and Valenciennes 1844) fingerlings

Abstract

Four shipments of grass carp imported from Indonesia were used for this study. The grass carp (Ctenopharyngodon idella Cuvier and Valenciennes 1844) fingerlings were infected by the monogenean (Dactylogyrus lamellatus Akhmerov 1952); protozoans (Trichodina spp., Trichodinella sp. , Trichophrya sp. , Cryptobia branchialis Nie, Ichthyophthirius multifiliis Fouquet 1876 and Piscinoodinium pillulare Schaperclaus 1954); trematodes (metacercariae of Echinostomatidae and Transversotrema sp.) and a crustacean (Argulus sp.).
