Abstract
The most specified wood borer Barnea candida’s has been recorded during three consecutive
years from 2015 to 2018 as live form in the river belt of Brahmani and Baitarani
mangrove dominated areas of Dhamra estuary. The carcasses of the observed wood borer
were found in huge number in and around of Dhamra Port. Present study further declared
that the range extension of Barnea candida occurred from Subarnarekha estuary to
Dhamra estuary by showing a southward migration.
During the survey, other molluscan dead shells were also observed along with the
wood borer which could be the consequences of port and harbour related activities.
It is well known that Barnea candida is an efficient substrate destructor of wooden
boats, shipwrecks, jetty pillars and also cemented structures of fishing harbours
in the marine and brackish water ecosystem. Therefore, the observed species might
be a threat for the Dhamra ecosystem in future which needs long-term integrated
research in future.
