摘要

Four separate cases of mortalities due to the dinoflagellate, Piscinoodinium spp. in juveniles of common carp, mahseer and tilapia occurring in rearing tanks of a fish farm in Mangalore were studied. Mortalities coinciding with decreasing water temperature were observed in September and October of 1996 and 1998. Clinical signs consisted of rust or dust colored appearance of the skin, lethargic swimming near the surface, gasping accompanied with conspicuos daily mortalities. Wet mount preparations of skin, fins and gills showed massive infection by the parasite. Trophonts of different sizes were found attached in large numbers in sections of skin and gill tissues. Massive gill and skin pathology induced by the attachment and feeding of the parasiteappeared to have contributed to the observed mortality.
