Species profiles are literature summaries of the taxonomy, morphology, range, life history, and environmental requirements of aquatic species. They are prepared to assist in environmental impact assessment. The white shrimp, Penaeus setiferus, is the most important commercial species in the Southern United States. It serves an important ecological role as food for other large invertebrates and fishes. Major bait industry is in northeast Florida and Georgia. Spawning occurs offshore within 9-m depth contour where salinities are at least 27 ppt. In spring, postlarval shrimp move with tidal currents into inshore estuarine waters. Juvenile white shrimp prefer shallow organichich substrate with low salinities (1-10 ppt). Nearshore soft sediment areas correlated well with white and brown shrimp distributions. Water temperature influences spawning, growth, habitat selection, emigration, and mortality. Low winter temperatures have greatly affected survival, recruitment, and harvest in the South Atlantic fishery. Maintaining suitable nursery grounds is a major concern for the future of the fishery.
