Bigeye Scad, Selar crumenophthalmus (Bloch 1793)

More Info


Distribution

Dampier Archipelago, Western Australia, around the tropical north to Forster, New South Wales; also in the Lord Howe Province in the Tasman Sea. Elsewhere the species is circumglobal in warm temperate and tropical waters.

Prefers clear oceanic waters around islands, also occurs inshore, including in turbid waters. A nocturnal species that forms large schools during the day, dispersing at night to feed.

Feeding

Usually feeds at night on large planktonic animals, including small fishes. Juveniles mostly consume crustaceans (euphasiids, decapods).

Fisheries

Taken with hook and line, beach seines, trawls, purse seines and traps in parts of its range.

Similar Species

Differs from the Oxeye Scad, Selar boops, in having 48–56 scales in the curved part of the lateral line (vs. 21–24 scales in S. boops), moderate sized scutes on the caudal peduncle (vs. large scutes) and the curved part of lateral line roughly equal in length to the straight part, 0.7 to 1.2 times in straight part (vs. 2.1 to 3 times in the straight part). 

Etymology

The specific name crumenophthalmus is from the Latin crumena (= purse, bag) and ophthalmos (= eye) in reference to the adipose eyelid that covers most of the eye, leaving just a vertical slit over the pupil - presumably resembling the opening of a purse.
