The number average species and average density of zoobenthos, with 20-25 species/location and 158-396 inds/m² respectively. Amongst 181 zoobenthos species, 15 species economic value and conserve, including 4 species are listed in the Red Data Book of Vietnam (2007). Species, that serve as natural food sources for fish and shrimp covered high number.
