Last year, the number of Irrawaddy dolphins sighted in the lake was 145.
During the latest survey, officials sighted 118 adult dolphins, 16 sub-adults and 18-calves and neonates, Ajit Patnaik, chief executive of Chilika Development Authority (CDA) told IANS.
Approximately 37.9 percent of the dolphins were sighted in the main Chilika lake with uniform distribution in the southern and central sectors, he said.
