Bhubaneswar: A team of scientists from Japan arrived here on Monday to study the the pattern of migration of the endangered Irrawaddy dolphins in Chilika lake which is the home of about 145 Irrawaddy dolphins.

A two-member team from Tokyo University has made an assessment on the feasibility of installing a permanent observation station at the mouth of the lake. They would study whether the dolphins were migrating from lake to sea or vice-versa. They would carry out the experiment till March 17.

The Chilika Development Authority is already conducting a long term study on the behaviour of dolphins in collaboration with the Tokyo University since 2006 and it has now decided to make some advanced studies on the dolphins for the conservation of this endangered species.
