| Abstract: | Green mussel, Perna viridis and the clam, Meretrix meretrix collected from Mumbai
waters were examined for the bioaccumulation of Paralytic Shellfish Toxin. Bioassay
experiment conducted on Mice, revealed accumulation of the toxin in sub lethal
amount. HPLC analysis showed that Crude toxin extract of P. viridis possessed GTX-2 & GTX-3 and
N-Sulfocarbamoyl toxins C1 & C2 . The extract from M. meretrix contained N-Sulfocarbamoyl toxins C1 & C2,
decarbamoyl toxins and carbonate toxins, i.e.
dcGTX/STX. These two shellfishes were subjected to Ozone and chlorine treatment
for depuration of the toxin. Specimens became nontoxic in 10 days of treatment
in ozonised water and 15 days treatment in chlorinated water. |
