In the western Atlantic, it also occurs in the Bahamas and the Caribbean. In Latin America it appears in Brazil, Colombia, Cuba, Haiti, Uruguay and Venezuela. It can be found in southern Brazilian waters, at slope depths. It is considered a sport fish and is also caught for subsistence.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the channel scabbardfish; in the meantime, see the similar species.
identification
Very elongated, compressed body, silvery with a slight reddish-brown tone on the back and several pale yellow longitudinal stripes. The lateral line is nearly straight, in the middle of the body. The pelvic fins are very reduced. Lepidopus caudatus looks similar, but has a uniform silvery body without the yellow stripes, and that is the main difference.
