400 species of fish found dead in Guwahati tank

Around 400 fish species, weighing around 600 kg, died in the Dighalipukhuri tank in Guwahati on Sunday.

Following the detection of dead fish floating on the water, Minister for Fisheries, Parimal Suklabaidya directed the officials of the department to visit the site and ascertain the cause behind it.

Officials of the department, after examination, found depletion of dissolved oxygen in the tank coupled with high organic load caused were behind the occurrence.


"Fish mortality was due to sudden dip in oxygen level and high organic load in the tank. Departmental officers after examination found deaths of fish not due to poisoning but environmental degradation," said Suklabaidya.

The department, as a short term measure, increased the oxygen level in water by showering water through pump and creating wave action through mechanised boats.
