Seagrass beds are habitat for many commercially and recreationally important finfish and shellfish during some stage of their life. In the northern Gulf of Mexico, turtlegrass, a type of seagrass, is a critical foundation species that provides energy for food webs and shelter and foraging grounds for many species. This management-driven project investigated the use of turtlegrass as habitat by finfish and shellfish at six sites across the Gulf of Mexico and evaluated the support provided to blue crabs (Callinectes sapidus), a commercially and recreationally fished species that has seen declines in harvest in many Gulf states.
