“The district authorities should take action against such constructions, as clean rivers are good for aquatic animals as well as for the people,” he said, appreciating the anglers from other States for participating in the tourment. Before the tourment, DFDO Yupia Dayum Davi released 5,000 fish fingerlings in the river with Toru CU, panchayat leaders, anglers and the local people. He emphasised fish conservation and said the tourment would go a long way in saving the endangered golden mahseer.
