Rhode Island Symbols, State Fish: Striped Bass

Adopted on July 13, 2000.

The state fish is the striped bass commonly measuring twenty to thirty inches in length and weighing three to ten pounds. If its habitat is favorable, the bass can reach sixty pounds and live up to thirty years.

The striped bass, Morone saxatilis, is an anadromous species distributed along the Atlantic coast from northern Florida to the St. Lawrence estuary. It has been successfully introduced in numerous inland lakes and reservoirs and to the Pacific coast, where it now occurs from Ensenada, Mexico to British Columbia.

Temperate basses have two dorsal fins (the first with usually nine spines and the second with one spine), three anal spines, a large mouth, ctenoid scales, thoracic pelvic fins, a large spine on the gill cover and a small gill on the underside of the gill cover. These fishes are popular sport fishes.

Common Names: Striper, Rockfish, Linesides

Identifying Features: Striped bass have a dark, olive-green to bluish-black back and silvery-white sides and belly. There are 7 to 8 black, unbroken, horizontal stripes along the side.

Typical Adult: 20-30 inches, 3-10 pounds. Striped bass can live in excess of 30 years under good habitat conditions and light fishing pressure. Hence they have the potential to reach 48 inches and 60 - 100 lbs or better.

Habitat: Striped bass are an anadromous species of fish. Anadromous fish inhabits both fresh water and salt water, depending on the time of year. Striped bass live in the Atlantic and Pacific coastal waters and the Gulf of Mexico but enter freshwater streams to spawn. The preferred water temperature is 65-75°F. In South Carolina, striped bass are found in Coastal rivers and estuaries, as well as large impoundments. Adult striped bass prefer water temperatures less than 75 degrees F and will often lose weight and suffer additional health problems when forced to live under warmer conditions. Their over riding selection for temperature can isolate them from prey and acceptable levels of oxygen.


Feeding Behavior: The diet of striped bass consists mostly of soft-rayed fish. Preferred species in fresh water are threadfin shad, gizzard shad and blueback herring. Striped bass commonly herd schools of prey fish against the surface, where their frenzied feeding can splash water several feet in the air. The heaviest feeding times are at dawn and dusk.

Reproductive Behavior (Spawning): Prior to spawning in early spring, striped bass migrate up rivers. Spawning occurs when water temperatures reach 60-70°F. Adults swim up tributary streams and spawn below dams or natural obstructions such as rock formations. The semi-buoyant eggs are released iin light to moderate current and fertilized by several males in a thrashing event known as a "fight". As many as 3,000,000 eggs may be released by one female. The eggs require a flow adequate to prevent their settling to the bottom during the incubation period of approximately 50 hours. During their first few days of life the larval fish are sustained by a yolk material while they continue to develop until they can feed on zoo plankton. Adults do not guard the eggs.
