have multiple uses, but island dwellers of Indian
Sundarbans are not at all aware of the same.
Awareness programme on regular basis through
government network is a tool to introduce the
concept of alternative livelihood to the people of
Sundarbans.
Taxonomic position and salient features of
some common seaweed found in the mangrove
ecosystem of Sundarbans are listed here.
