181 Irrawaddy dolphins counted in Odisha census

181 Irrawaddy dolphins counted in Odisha census As many as 181 endangered(लुप्तप्राय)  Irrawaddy dolphins have been sighted in Odisha, according to a census carried out by the State Forest and Environment department on January 20. In 2015, survey teams had sighted 206 Irrawaddy dolphins here. The dolphin census in Odisha in 2016 was suspended because of lack of visibility(दृश्यता)  due to

cloudy (धुंधला) weather, high wind speed and surging waves but researchers, government officials and wildlife enthusiasts (उत्साही) took up the survey again this year. Humpback dolphins (34), bottlenose dolphins (31) and five non-tropical spotted dolphins were also sighted. This marks a significant drop from 2015, when survey teams recorded 450 dolphins.

The Chilika Lake, the largest brackish water lagoon (खाड़ी) of the country, has recorded a marginal drop in the population of Irrawaddy dolphins from 144 in 2015 to 134 this year. About 55 dolphins were sighted this year in Bhitarakanika, compared to 58 spotted in 2015. In the Bhadrak Wildlife Sanctuary (अभयारण्य) jurisdiction(अधिकार - क्षेत्र) , only five Irrawady dolphins were sighted.

Forest department sources said that sighting of dolphins depended on the weather condition of the day the census was carried out.

“Migration of dolphins continuously takes place in waters close to the coast. While endangered Irrawaddies are found in three places, humpback and bottlenose dolphins are not distributed uniformly in the State,” said a senior Forest Department official.
