Biogenic reefs formed by dense aggregations of the eastern oyster, Crassostrea virginica , are dominant features in estuarine systems along the Atlantic and Gulf of Mexico. These reefs may provide critical habitat for several species of fishes and invertebrates due to the prey availability and predation refuge afforded by the structural complexity of the reefs.  

Oyster reef, potential refuge for earlyjuvenile fish, shrimp, and crabs.

Few studies have quantitatively assessed the use of oyster reefs by fisheries species, primarily due to inefficiency of conventional gear to adequately sample this habitat.  Currently, we are  sampling small patches of oyster reefs using a drop sam pler to examine use of this habitat  by nekton.  Identifying and quantifying the habitat role of oyster reefs, particularly in relation to other habitat types, is critical in implementing effective management and protection measures for Essential Fish Habitat (EFH).
