BAIJI DOLPHINS - Japanese team to study Chilka lake dolphins

Interesting news from the Indian Business Standard on another endangered animal. A Japanese research team is to employ techniques formerly used to study the endangered Baiji Dolphin to study the . Irrawady Dolphins of Chilika Lake
A team of Japanese scientists, in collaboration with researchers in India, will undertake a study of Irrawady Dolphins, inhabiting the Chilika Lake in Orissa, using acoustic technology.

This is the first time that a study using such technology is being conducted in the country, Ajit Patnaik, chief executive of the Chilika Development Authority (CDA) said.

Specially designed hydrophones, an underwater acoustic device, caught these sounds as 'clicks' of a specified duration and bandwidth, he said.

The Indo-Japan research team would use such customised hydrophones to track these 'clicks' which were emitted in a confined beam. Such technology was used to observe the behaviour of Chinese river dolphin 'Baiji' which used its sonar pulses for finding prey, Ura said.
