Pensacola Bay is is partially sheltered by barrier islands to the south. Bayou Grande is a shallow protected inlet of Pensacola Bay. Little is known about the aquatic habitats in this embayment, but its physical characteristics are similar to the sheltered, lowersalinity nursery areas in the upper reaches of the Pensacola estuary. Significant amounts of eelgrass habitat have been lost within Bayou Grande since the 1970s.Shallow estuarine environments play an important role in the recruitment of numerous fish species to the Gulf of Mexico. Several species, such as ladyfish, sheepshead, members of the drum family (drums and seatrout), and mullet are dependent upon estuaries during their early life history.Some of the most abundant were spot, pinfish, Atlantic croaker, gulf menhaden, bay anchovy, longspine porgy, silver perch, southern hake, inshore lizardfish, gafftopsail catfish, sand seatrout, and spotted hake.
