One of the important things they do is regulate the growth of the native SAV plants. This species also helps the bay community by providing food for the secondary consumers, the Chesapeake Blue Crab and Menhaden. Last but not least, grass shrimp break down food into tiny particles that float in the water, providing a rich food source for smaller crustaceans and organisms. 

This is a short video of Chesapeake Menhaden feeding on zooplankton similar to grass shrimp.
