Species Profiles: Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (South Atlantic). Spot

摘要

Species profiles are literature summaries of the life history, distribution, and environmental requirements of coastal fishes and invertebrates. Profiles are prepared to assist with environmental impact assessment. The spot (Leiostomus xanthurus) is an abundant fish in coastal waters of the South Atlantic Region. It is important to commercial and recreational fisheries. In the South Atlantic Region, spot spawn offshore from October to March. The larvae are transported from the offshore spawning grounds to estuarine nursery areas. Juvenile spot initially congregate in shallow tidal creeks, but then disperse into deeper water as they get larger. Spot mature at 2-3 years of age. As larvae, spot feed on plankton, but switch to benthic invertebrates as juveniles and adults. Alterations of the salinity or temperature regimes of an estuary may affect populations of spot; disturbances that affect the benthic community upon which spot feed may also affect spot abundance.
