Bhubaneswar: Dolphin census started in Chilika, the brackish water lake today.
A total of 18 teams having around 75 persons, including forest department officials and OUAT scientists were engaged for the purpose.
Chilika, a Ramsar site (i.e. a wetland of international importance) since 1981, incidentally, has the largest lagoonal population of Irrawaddy dolphins in the world.
While 10 teams were conducting the census in Balungaon range eight teams were busy in counting the dolphins in Satpada range.
Last year, Chilika Lake recorded marginal drop in the population of the species from 144 in 2015 to 134 this year.
As many as 181 endangered Irrawaddy dolphins were sighted in Odisha, according to a census carried out by the State Forest and Environment department on January 20, last year.
