Indo-West Pacific: west coast of India and Sri Lanka eastward to Thailand, Malaysia and Java (Ref. 9684). Does not extend further out in the East Indies (Ref. 9684).
Length at first maturity / Size / Weight / Age
Maturity: Lm 70.0  range ? - ? cm
Max length : 94.0 cm FL male/unsexed; (Ref. 168); 98.0 cm (female); common length : 70.0 cm FL male/unsexed; (Ref. 9684)
(total): 15 - 18;
soft rays: 17 - 22;
Vertebrae: 44 - 46. A unique pigment pattern of short lines on the sides which distinguishes from all other species of Scomberomorus; maxilla with the posterior end greatly expanded; parasphenoid wide (Ref. 10996). Interpelvic process small and bifid. Lateral line without auxiliary branches anteriorly, running almost straight below second dorsal finlet then slightly bent downward toward keel of caudal peduncle. Intestine with 2 folds and 3 limbs. Swim bladder absent. Body covered with small scales. First dorsal fin black posteriorly.
Unlike S. commerson and S. guttatus, S. lineolatus is not encountered in very turbid waters or much reduced salinity. Feeds primarily on fishes. Also taken with midwater trawls, purse seines and by trolling (Ref. 9684). Taken from Oct.-Nov. along the Thai coast, Indian Ocean; in Malaysia Nov.-Feb. in the west coast, Mar.-Jul. in the south, Feb.-Mar. and Aug.-Nov. in the east; in India from May-Sept. with other seerfishes. Marketed mainly fresh; also dried-salted (Ref. 9684). Also consumed as spicy fishballs.
