FBname: Double-lined mackerel
Comments: Inhabits open water but often seen swimming near outer reef walls or deep clear-water slopes (Ref. 48637).  Found mostly in shallow reef waters where it forms large schools.  Feeds on crustaceans and fishes, particularly clupeoids (<i>Sardinella</i>, <i>Thrissocles</i>), and other fishes such as <i>Sphyraena</i> and <i>Balistes</i>.  Marketed canned and frozen (Ref. 9684).  Its flesh is mild and pleasantly flavored, but brushed with lemon juice prior to cooking to remove the ammonia-like smell (Ref. 9684).
