Pesticides may be a cause, say experts

Ludhiana, June 23 Industry and the Buddah nullah are not the only factors to be blamed for the fish mortality witnessed at Harike Pattan downstream. While teams from the Punjab Pollution Control Board (PPCB) and Guru Angad Dev Veterinary and Animal Sciences University have dispatched their separate teams to look into the factors, yet experts say presence of high level of muddy waters in canals, reduction of dissolved oxygen in water, pesticides leeching into canals due to rains or rivalry between fish contractors could also contribute to this kind of mortality.
