Abstract
The toxicity of Croton tiglium seed is very effective in the eradication of most of
the aquatic fauna except a few species of hard shelled crustaceans such as crabs and
prawns which are resistant to even very high concentrations of it. Its toxicity ranged
between 0.4 and 2.2 p.p.m. for different species of fishes. Application of homogenised
C. tiglium seed at the rate of 10 kg/ha (0.5 m depth) is found effective for the eradication
of aquatic pests and predators of fish farms. While its toxicity lasts for 5-8 days
in still water ponds, it is only for 1-3 days in tidal ponds with frequent replenishment
of water. This method is thus most useful for the initial preparation of the ponds for
pisciculture.
