About the species

U.S. wild-caught brown rock shrimp is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.

Maryland record catch

Confirm whether Maryland DNR publishes an Atlantic state-record category for Brown Rock Shrimp on the current sport-fish record board.

Verify on Maryland DNR — Sport Fish State Records . Record boards change when DNR accepts a new fish.

Maryland size & bag limits

Maryland’s Atlantic recreational seasons/sizes/creel summary does not publish a dedicated line for Brown Rock Shrimp. Verify COMAR, DNR public notices, and federal rules for your exact waters before you keep fish.

Rule Maryland / applicable detail
Maryland minimum size Not listed — no dedicated Brown Rock Shrimp line on the MD Atlantic recreational table

Population & fishing rate

Brown rock shrimp have a thick, rigid, stony shell.

Their bodies are off-white to pinkish in color, with the back surface darker and blotched or barred with lighter shades.

Their legs are red to reddish-purple and barred with white.

The abdomen has deep transverse grooves and numerous nodules.

Short hairs cover their body and appendages.

Their eyes are large and deeply pigmented.

Appearance

  • Brown rock shrimp’s growth and development depends on factors such as water temperature and salinity.
  • They can grow up to 6 inches in length, but most brown rock shrimp found in shallow waters are less than 2 inches long.
  • They are highly productive and have a short life span, between 20 and 22 months.
  • Females are able to reproduce when they reach at least ½ to 1 inch in length.
  • Males mature when they reach about ½ inch long.
  • Brown rock shrimp spawn year-round in offshore waters, with peaks between November and January.
  • Individual females can spawn three or more times in one season.
  • Males and females mate, and the eggs are fertilized when the female simultaneously releases egg and sperm.
  • Juvenile and adult brown rock shrimp feed on the ocean floor, mainly eating small bivalve mollusks and crustaceans.
  • Sheepshead, minnows, water boatmen, and insect larvae eat postlarval brown rock shrimp.
  • A wide variety of species prey on juvenile and adult brown rock shrimp.
  • Where They Live Range Brown rock shrimp are found from Norfolk, Virginia, south through the Gulf of America (formerly Gulf of Mexico) to Mexico’s Yucatan Peninsula.
  • Habitat Brown rock shrimp mainly live on sand bottoms in water 80 to 215 feet deep, although they’ve been found in depths to 600 feet.
  • They are active at night and burrow in the sand during the day.
  • Larval brown rock shrimp grow and develop in coastal estuaries and travel back to offshore areas as they mature.
  • Fishery Management NOAA Fisheries and the South Atlantic Fishery Management Council manage the brown rock shrimp fishery.
  • Managed under the Shrimp Fishery Management Plan : Permits are required to harvest shrimp in federal waters.
  • Trip reports must be submitted for each fishing trip.
  • Observers must be carried aboard selected vessels to collect data on catch, bycatch, fishing effort, and fishing gear.
  • Managers set catch levels based on historic harvest amounts and fishing rates, rather than abundance, because brown rock shrimp are short-lived and heavily influenced by environmental factors.
  • Vessels are prohibited from trawling in certain areas off Florida to protect deepwater coral habitat.
  • To ensure compliance, brown rock shrimp vessels must carry vessel monitoring systems .
  • Brown rock shrimp are occasionally caught in the Gulf of America but not in quantities large enough to warrant specific management measures.
  • Harvest Commercial fishery: In 2024, landings of brown rock shrimp totaled 4.2 million pounds and were valued at $9.9 million, according to the NOAA Fisheries commercial fishing landings database .
  • It is not uncommon for brown rock shrimp to experience considerable variations from year to year.
  • Brown rock shrimp had limited marketability before 1969, when a machine was developed that could split the rock-hard shell and devein the shrimp.
  • The first major harvest of brown rock shrimp (1,200 pounds) was recorded in 1970 and was valued at $642.
  • Two years later, landings totaled 443,035 pounds and were valued at more than $258,000.
  • Almost all the harvest is sold as meat because brown rock shrimp are difficult to peel.
  • Gear types, habitat impacts, and bycatch: Commercial fishermen harvest shrimp with trawls towed near the ocean floor.
  • Shrimpers using otter trawl gear in the South Atlantic and Gulf of America are required to use sea turtle excluder devices (TEDs) .
  • Some shrimp trawlers must also install bycatch reduction devices behind the TED, to reduce finfish bycatch.
  • Area closures if finfish bycatch exceeds certain thresholds.
  • Fishermen do not trawl in areas with coral reefs and other known areas of high relief to avoid damage to their nets.
  • Recreational fishery: Under federal management, there is no recognized recreational fishery.
  • Fishing in federal waters requires a permit.
  • Recreational fishermen catch brown rock shrimp seasonally and almost always in state waters.
  • State regulations vary from state to state.
