生態学
海 pelagic-neritic; 海洋回遊性 (Ref. 51243); 深さの範囲 10 - 35 m (Ref. 26912). Subtropical; 20°C - 30°C (Ref. 54882); 44°N - 19°N, 97°W - 64°W (Ref. 54882)
Western Atlantic: Canada (Ref. 5951) to Cape Cod to Miami (USA) and Gulf of Mexico coasts from Florida, USA to Yucatan, Mexico. Three species namely: Scomberomorus tritor in eastern Atlantic, Scomberomorus sierra in eastern Pacific, and Scomberomorus brasiliensis in the Caribbean and Atlantic coast of South America have often been confused with this species. Absent in the Bahamas (Ref. 26938).
Length at first maturity / サイズ / 重さ / 年齢
成熟: Lm 40.5, range 25 - 51.2 cm
Max length : 91.0 cm FL オス/雌雄の選別がない; (Ref. 40637); 最大公表体重: 5.9 kg (Ref. 40637); 最大記録サイズ: 5 年 (Ref. 72462)
背面の脊椎 (合計) : 17 - 19; 背鰭 (合計) : 17 - 20; 臀鰭: 17 - 20; 脊つい: 51 - 53. Interpelvic process small and bifid. Lateral line gradually curving down toward caudal peduncle. Vertebrae 21-22 precaudal plus 30-31 caudal, total 51-53. Intestine with 2 folds and 3 limbs. Swim bladder absent. Body covered with small scales. First dorsal fin black anteriorly and at distal margin posteriorly. Generally silvery with sides marked with about three rows of round to elliptical dark spots (orange in life).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Migrates in large schools over great distances along the shore. Larvae are found in surface waters between 19.6° and 29.8°C with salinities of 28.3 to 37.4 ppt. Feeds mainly on small fishes (clupeoids and anchovies), few quantities of penaeoid shrimps and cephalopods. Casting, live-bait fishing, jigging, and drift fishing are also employed in capturing this species. Aerial spotting is sometimes used in locating the fish. Marketed fresh, frozen or smoked; eaten pan-fried, broiled and baked.
