Abstract
Effect of aflatoxin contaminated feed on growth, survival and behaviour of the fish Labeo rohita was evaluated. There was a significant decrease in the growth rate and survival percentage of the fish with the increase in the amount of aflatoxin contaminated feed in the food of the fish.
Highlights
Aflatoxin is the metabolic by product of mols Aspergillus flavus and Aspergillus parasiticus.It is a toxic compound and the cause of high mortality in livestock, poultry and in some cases of human beings (Reed and Kasali.,1987, Montessano et al.1995)
Nunez et al (1991) reported hepatocellular adenoma and hepatocellular carcinoma in Rainbow trout when exposed to aflaroxin B1.Caguan et al (2004) reported loss of appetite, low survival percent and decreased mean total biomass in tilapia when fed with aflatoxin contaminated feed
In the present investigation effect of aflatoxin on growth rate, survival percentage and behavioural changes of Labeo rohita has been evaluated in order to explore the effect of toxin in the fish
Summary
Aflatoxin is the metabolic by product of mols Aspergillus flavus and Aspergillus parasiticus.It is a toxic compound and the cause of high mortality in livestock, poultry and in some cases of human beings (Reed and Kasali.,1987, Montessano et al.1995). Parasiticus produces Aflatoxin G1 and G2.Aflatoxin B1 is classified as group I carcinogen by international agency for research on cancer. Effect of aflatoxin on fishes and other animals have been reported by many workers. Labeo rohita a common Indian carp is widely distributed in Indian rivers and ponds. It is very important as a human food for its high quality flesh. In the present investigation effect of aflatoxin on growth rate , survival percentage and behavioural changes of Labeo rohita has been evaluated in order to explore the effect of toxin in the fish
