Climate change impacting fish reproduction in the Sundarbans: Study
Some of West Bengal’s most-loved fish may go off the menu, thanks to climate change in the Sundarbans.
A team of researchers that is mapping biological sensitivity of certain fish species to climate change says increasing salinity and temperature in the Sundarbans estuary is messing up their reproductive behaviour and may also likely alter their abundance, factors that could wipe them out one day, they warn.
Spanning 10,000 square km along the coast of India and #Bangladesh, the Sundarbans represent the largest expanse of contiguous mangrove forests in the world. This globally significant ecosystem is situated in the Bay of Bengal, within the delta of the Ganges, Brahmaputra, and Meghna rivers.
The Indian Sundarbans archipelago acts as the “nursery” for nearly 90 percent of the aquatic species of eastern coast of India. It is the top producer of fish and prawn, with both districts (South and North- 24 Parganas) combined producing roughly 31 percent of the total inland fish/prawn production of West Bengal, a state iconic for its fish-eating habits. Sundarbans also satiates 15 to 20 percent of the state capital Kolkata’s fish requirement.
