Migration
provided by Fishbase
Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.
Biology
provided by Fishbase
Inhabits neritic and oceanic waters but more often found near islands (Ref. 5213). Found in estuaries (Ref. 26340), and coastal rivers (Ref. 33587). Sometimes forming large schools (Ref. 5217). Feeds mainly on small fishes (Ref. 9279). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by filaments on the egg's surface (Ref. 205). Since the jaws are frequently broken, the maximum length is given as body length excluding head and caudal fin. Usually caught with the help of artificial lights (Ref. 9279). Marketed fresh and salted; smoked or frozen (Ref. 9987). Market limited due to the green-colored flesh (Ref. 5217). In females, only left gonad is developed, and in males the right gonad is small or absent (Ref. 26938).

Flat needlefish
provided by wikipedia EN
The flat needlefish (Ablennes hians), or barred longtom,[3] the only known member of the genus Ablennes, is a marine fish of the family Belonidae. Flat needlefish are considered gamefish, frequently caught with the help of artificial lights,[4] but are not often eaten because of their green-colored flesh.[5]
The generic name Ablennes – formerly misspelled Athlennes – means ‘without mucosity’,[6] from the ancient Greek privative a- prefix and blennos (‘mucus’). Its specific name hians is Latin for "gaping".
Description
Although they have no spines, they do have several soft rays. About 23-26 rays are on the dorsal fin and 24-28 are on the anal fin.[7] They have 86-93 vertebrae.[7] Dorsally, flat needlefish are blueish, white ventrally, with dark blotches and 12-14 vertical bars in the middle of their bodies.[8] Flat needlefish have elongated bodies, with scythe-shaped pectoral and anal fins.[7] They also have a dark lobe on the posterior part of their dorsal fins.[7]
The longest recorded flat needlefish measured 140 cm.[9] Measurements for flat needlefish body length do not include their caudal fins and heads because the fish's long jaws are often broken off.[7] The largest recorded weight for a flat needlefish was 4.8 kg.[9]
Distribution and habitat
Flat needlefish are found worldwide in tropical and temperate seas.[7] In the Eastern Atlantic, they are known from Cape Verde and Dakar to Moçamedes in Angola.[10] In the western Atlantic, they are known from the Chesapeake Bay south to Brazil.[11] They are found throughout the Indian Ocean,[7] and in the western Pacific from the southern islands of Japan to Australia[12] and Tuvalu.[13] A few specimens have been collected from Syria to Israel in the Mediterranean Sea,[14] likely migrants from the Red Sea.
Flat needlefish usually live in neritic ocean waters near islands,[15] estuaries,[16] and near coastal rivers,[17] where they feed on smaller fish[4] and occasionally gather in large schools.[5]
Reproduction
Flat needlefish lay eggs, which attach themselves to floating debris by filaments on the surface of each egg.[18] Only the left gonad in both sexes is developed, and in males, the right gonad is sometimes wholly absent.[19]

Description

Inhabits coastal and oceanic waters but more often found near islands (Ref. 5213). Feeds mainly on small fishes. Marketed mostly fresh and salted. Utilized also smoked and frozen (Ref. 9987). Reaches at least 120 cm in total length or 90 cm body length (excluding head and caudal fin) and because the jaws are frequently broken, the latter measurement must be used (Ref. 9682).
