PFRI has been actively involved in safeguarding coastal and marine ecosystems. Our efforts over the past year have been concentrated on comprehending, protecting, and advancing sustainable methods to guarantee these essential ecosystems' improved resilience and health. Our research aimed to identify the vulnerable species, indicating point and nonpoint sources of pollution sources, and assessment of the impact of human activities as well as the level of anthropogenic stresses on these ecosystems. The project work was mainly conducted in different regions of the Indian Sundarbans.
