Common names: Linesider, Rockfish, Roccus
Occurrence: native

Abundance: fairly common (chances are about 50%) | Ref: Page, L.M. and B.M. Burr, 2011
Importance: minor commercial | Ref: FAO, 1994
Aquaculture: | Ref:
Regulations: | Ref:
Uses: live export: yes;
Comments: Type locality, New York (Ref. 79012). Introduced into Pacific coast drainages and freshwater impoundments far inland (Ref. 5723). Uncommon south of Monterey Bay (Ref. 11545) and north of Coos, Bay, Oregon (Ref. 6885). Most stocks on the east coast are reserved for recreational fishing; little interest for consumption on the west coast (Ref. 9988). Present inshore north of Cape Hatteras (East Coast) (Ref. 37512). A popular fish sold in live fish markets. Found in 2 out of 6 live fish markets near the Lakes Erie and Ontario (Ref. 53249). Fairly common, but less so than before due to pollution of major spawning grounds (Ref. 86798). Hybridized with Morone chrysops. The hybrids known as "wipers" are common where Morone saxatilis have been introduced (Ref. 86798). Also Ref. 1998, 6885, 10294, 37512. Status of threat: 1). Gulf of Mexico populations: vulnerable. Criteria: 1,4; 2). Southern Gulf of St. Lawrence population: threatened. Criteria: 1; 3). St. Lawrence Estuary population: possibly extinct. Criteria: 1 (http://fisc.er.usgs.gov/afs/) (Ref. 81264).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9 - 11; Dorsal soft rays (total): 10 - 13; Anal spines: 3; Anal soft rays: 7 - 13.

Inhabit coastal waters and are commonly found in bays but may enter rivers in the spring to spawn (Ref. 2850). Some populations are landlocked (Ref. 7251). Voracious and opportunistic feeder (Ref. 5951). Larvae feed on zooplankton; juveniles take in small shrimps and other crustaceans, annelid worms, and insects (Ref. 1998, 10294); adults feed on a wide variety of fishes (alewives, herring, smelt, eels, flounders, mummichogs, rock gunnels, sand lance, silver hake and silversides (Ref. 5951)) and invertebrates (squid, crabs, sea worms and amphipods (Ref. 5951)), mainly crustaceans (Ref. 1998). Feeding ceases shortly before spawning (Ref. 1998). Utilized fresh and eaten broiled and baked (Ref. 9988).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Move into fresh or brackish water to spawn (Ref. 39467). Females spawn more than once in a season, but they don't necessarily spawn every year (Ref. 1998).
