Black sea bass
The black sea bass is an exclusively marine
fish, also known as sea bass and blackfish.
It inhabits the coasts from
Maine to NE
Florida and the eastern
Gulf of Mexico.
They are most abundant off the waters of
New York. They can be found in inshore waters and offshore in waters up to a depth of 130 m. They spend most of their time close to the sea floor and are often congregated around bottom formations such as rocks, man-made reefs, wrecks, jetties, piers, and bridge pilings.

General characteristics
Black sea bass, as their name indicates, are usually black. But like many other types fish, they have the ability to adjust their color to blend in with the bottom. Their colors may take on a gray, brown, black or even a deep indigo hue. The sides of their body may have dark vertical bands. But most distinctive is their skin, when seen up close resembles a fishnet pattern, because of the dark color that appears in the margin of their scales contrasted with the lighter color underneath the scales.
The average sea bass weighs about 1½ lb . The world record bass is 9 lb 8 oz , but any sea bass above 5 lb is considered a large fish. As a sea bass matures, there are slight variations in their proportions. The smallest sea bass are often nicknamed “pin” bass. Larger fish are nicknamed “humpback” bass because as they grow larger they tend to bulk out just behind the head.
Black sea bass feed on
crab, bluecrab, juvenile
lobster,
shrimp,
mollusks, small fish,
herring,
menhaden and
squid.
In contrast to the Striped bass
Morone saxatilis, it is strictly confined to salt water.
Life cycle
The sea bass spawns when it is mature, at 190 mm, in middle of May to end of June. The eggs, 0.95 mm in diameter, are
buoyant and their development time is 1.6 days at 23 °C. The maximum size of a sea bass is 500 mm, weighing 4.3 kg.
It appears off
New Jersey in the first weeks of May, withdrawing in late October or early November, and wintering offshore at 55 to 130 m at temperatures above 8 °C. In summer it is most abundant at less than 37 m.
Diagnostic features
- The spiny and soft ray portions of the dorsal fin are continuous, so there is only one long fin instead of two short separate ones as for the wreckfish
...
Polyprion americanus,
scup Stenotomus chrysops,
rose fish Sebastes marinus,
cunner Tautogolabrus adspersus,
striped bass Morone saxatilis.
- Rounded caudal fin and pectoral fins, short but high anal fins.
- Compared to a tautog or cunner, its mouth is much larger, also the caudal fin, pectoral fin, and soft portion of dorsal fin as long as spiny portion.
- Compared to a wreckfish, its scales are much larger, the head outline and gill cover are smooth, and the caudal fin is rounded at the edges.
- It is stout-bodied, three times taller than long , and has a high back, flat topped head, moderately pointed snout, large oblique mouth, eye set up high , and one sharp flat spine near the caudal end of the operculum.
- The dorsal fin originates at the anterior of the caudal end of the operculum, the soft portion of the dorsal fin is more tall than long, the caudal fin is rounded and in adults it is an elongated upper ray, the anal fin originates below the soft portion of the dorsal fin, which it resembles in its rounded shape and being more tall than long.
- The pectoral fin is very long nearly towards the anal fin, rounded , the pelvic fin is very large, originate posterior of pectoral fin .
- Scales are very large but it is naked at the head with adult males developing fatty bumps in front of the dorsal fin.
It often rests stationary or cruises slowly around structures. It occasionally rests on the bottom or other structures, staying either head-down or head-up. It enters the smallest corners and caves with a body angle above ground often about 40° down. The dorsal fin is normally folded close to the body, and it is only spread out as an aggressive posture reaction to other sea bass.
