Biology & Habitat

Appearance

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.

Biology

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.

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.

Commercial Fishery & Harvest

Commercial fishery: In 2023, landings of brown rock shrimp totaled 600,00 pounds and were valued at $1 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.
