Acute Aflatoxicosis in Catla Catla: An Experimental Study

Aflatoxicosis due to acute toxicity was studied through two experimental trials conducted on Indian major carp, Catla catla using crude as well as pure aflatoxin B. In the first experiment where fishes were fed crude toxin mixed with diet @ 5 mg/kg, no clinical sign as mortality could be observed, whereas in the second experiment where pure aflatoxin B was fed with the diet @ 0.5 mg/kg resulted in 40% mortality with signs of lethargy, listlessness and excess mucus secretion. Histopathological alterations in the liver, kidney, spleen, heart and gastrointestinal tract have been described and discussed.
