Mangrove estuaries such as those found in the Sundarbans of southwestern Bangladesh are rich productive ecosystems which serve as spawning grounds and nurseries for shrimp, crabs, and many fish species, a richness which is lost if the area is cleared and converted to ponds for shrimp farming or rice paddies.
