Black sea bass facts

  • Species name: Centropristis striata
  • Black sea bass live along the Eastern coast of the United States, from Maine to the Gulf of Mexico. They are most commonly found between Long Island, New York, and South Carolina.
  • Black sea bass migrate seasonally, inhabiting inshore waters from the late spring through the fall and then migrating to warmer, deeper waters for the winter. Black sea bass are common in rocky, complex habitats. 
  • Ocean temperatures in the Northwest Atlantic have been gradually warming over recent decades; this warming trend has been associated with a northernly expansion of the black sea bass population. 
  • Black sea bass are protogynous hermaphrodites. This means each individual changes sex at some point in their life. Most fish do this before six years of age.
  • In New England waters, mature sea bass will reproduce from mid-May through July. The eggs float in the ocean until they hatch 2 to 5 days after fertilization. Larvae are carried into bays, inlets, and offshore areas. 
  • Crabs and shrimp are common prey of the black sea bass. The fish will also snack on small fishes, squid, clams, and barnacles. Predators of the black sea bass are bluefish, weakfish, bignose shark, and dusky shark.
  • Black sea bass is an important commercial and recreational fishery in Massachusetts waters. Commercially, black sea bass are commonly harvested with fish pots and to a lesser degree rod and reel. Be sure to review our commercial and recreational before hitting the water.
