Chilika lagoon, located on the east coast of India, is a Ramsar site and an important biodiversity hotspot in Asia. Apart from supporting a large number of bird species, it is also rich in several species of harvested fish and serves as a means of livelihood to many fishermen. The lagoon is also home to the Irrawaddy dolphin, Orcaella brevisrostris. This population of dolphins is geographically isolated, and therefore possibly severely threatened.
While recent population estimates range from 85 to 130 individuals (using both direct counts and photo-ID techniques), mortality data from 2002 to 2006 indicate an average of around 8 deaths per year. The main causes of mortality during this time period were found to be entanglement in fishing gear and collisions with mechanized boats, reflecting prevailing conflicts with the local fishing community and tourist boat operators. Although management authorities have taken enforcement measures to control gill netting and collision related mortality, the efficacy of these management strategies has not yet been quantified.
The study herein will therefore focus on key aspects regarding the demography and population dynamics of the Irrawaddy dolphin at Chilika lagoon to allow for an assessment of the effectiveness of currently used management strategies. This project will commence in January 2008.
