According to Hussain Bux Bhagat, the conservator of the Wild Life Department, Sukkur, officials of the agency rushed to Dadu upon learning that a blind dolphin was struggling for life after straying into the canal.
The conservator said it took six hours to extricate the three-year-old female dolphin from the water.
The Wildlife Department later released it into the Indus near Sadh Belo temple. The animal measured four feet in length and weighed 20 kilograms.
