Ayub Khan, Forest Ranger, Kodiakarai, said the forest department had passed on the information to the district administration and other top government officials.
The ranger pointed out that dolphins are found in large numbers near the Kodiakarai-Vedaranyam coast every year between November and April.
"Destructive fishing practices like pair-trawling and use ofpurseseinefishing nets could potentially cause damage to the dolphins. These fishing practices have been banned by the Government," he said.
