Abstract

This review synthesizes the available information on the climate variability, fisheries resources and aquaculture activities in the Sundarbans. The article also focuses on the possible impact of temperature and sea level rise, salinity intrusion, impaired freshwater supply, precipitation variability, acidification, and tropical storm surges on the fisheries and aquaculture in and adjacent areas of the Sundarbans as well as dependent fisher-folk communities. It prescribes some adaptation and mitigation measures as well. The synthesis implies that the distribution, abundance, and spawning habit of the Sundarbans fisheries stock of more than 227 species and their recruitment processes needs to be changed. The sea level rise (0.30-1.5m by 2030) and salinity intrusion (16% by 2050) may open door for marine fisheries of euryhaline type and crustacean species, and coastal-aquaculture (e.g. farming of sea-bass, mullet, shrimp, and mud crab). Nevertheless, stenohaline fish species may extinct. The frequent tropical cyclone and flood in recent years resulted in the alteration of the Sundarbans ecosystem, loss of biodiversity and damages to aquaculture farms, and thus livelihood of fisher-folks are at risk. Breeding protocol and adaptive farming technology of suitably saline tolerant fisheries species, reforestation, river restoration, integrated protected area management, and the resilience capacity of the fisher-folk communities must be developed for sustainable fisheries and aquaculture in the Sundarbans and adjacent areas.
