Annual Dolphin Census Kicks Off at Chilika Lake Using GPS Technology
In a significant step for wildlife conservation, the annual dolphin census at Chilika Lake began early this morning. The systematic survey aims to assess the population, distribution, and movement of dolphins across the lagoon’s various sectors, strengthening conservation efforts in India’s largest brackish water lake.
The census, starting at 6 am, will run until 22nd January 2026, with 18 specialised teams deployed. Each team consists of one expert and five to six trained enumerators, ensuring accurate data collection using advanced technology.
Teams, Routes, and Technology
Ten teams departed from Balugaon, while eight teams started from Satapada, covering 18 designated routes spanning the southern, northern, and central sectors of Chilika Lake, including the outer channel. GPS-enabled boats are following fixed transect lines, supported by binoculars, range detectors, drones, and compasses, to ensure precise dolphin counts.
Wildlife officials explained, “The dolphin census began today at 6 am from two GPS base points at Satapada and Balugaon. All 18 teams are covering clearly defined routes following the methodology prescribed by the Chilika Development Authority. Volunteers from WWF, WTI, OUAT, other government and non-government organisations, and wildlife experts are participating. We expect the census to be completed by 12 noon,” said Amlan Nayak, DFO, Wildlife Forest Division, Balugaon.
Boat Restrictions to Aid Survey
To avoid disturbances during the census, authorities have requested motor boat associations to suspend operations in Chilika Lake from 6 am to 12 noon, ensuring smooth execution of the survey.
With meticulous planning and strict monitoring, this GPS-based dolphin census is expected to deliver crucial insights into Chilika dolphin population trends, helping reinforce conservation strategies and support the preservation of this endangered species.
