More fish species on the east coast, especially in the waters off Odisha and West Bengal, are highly vulnerable to climate change, according to a first of its kind assessment by the Central Marine Fisheries Research Institute (CMFRI).
That vulnerability stems not only from changes in climate but also from fishing pressure and lower productivity.
Overall, 69% of the 68 fish species studied were found to be vulnerable to climatic changes. They include Bombay duck, tuna, sharks, various shrimp, pomfret, and catfish, among others. “The west coast also has high fishing pressure but is richer in fish so it is a bit less vulnerable,” said Dr P U Zacharia, CMFRI scientist and lead author of the report.
