Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 16 - 19; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 34 - 42. Diagnosis: Body moderately deep, compressed, belly with strongly keeled scutes, 17-20 pre-pelvic and 8-10 post-pelvic scutes, with a total of total 25-29 scutes (Ref. 188, 6867). Eye large; lower jaw projecting; upper jaw with a toothed hypomaxillary bone between hind tip of pre-maxilla and lower bulge of maxilla blade; lower gillrakers 22-27; dorsal fin origin near midpoint of body; pelvic fins present; anal fin with 34-42 finrays; scales with upper and lower vertical striae slightly overlapping each other at centre of scales (Ref. 188). It closely resembles Pellona dayi, which has only 20-21 lower gillrakers and the vertical scale striae not meeting at centre of scale; species of Ilisha have no hypomaxilla; other pristigasterids are much more slender and lack pelvic fins (Ref. 188).
A pelagic species found in coastal areas (Ref. 2871, 6867) at depths from 6 to 36 meters (Ref. 3225); occasionally entering mangrove swamps and penetrating estuaries into freshwater (Ref. 188, 3509, 54703). Apparently fully euryhaline (Ref. 188). Marketed fresh and may be dried or salted (Ref. 5284). Regarded as an excellent bait in the tuna fishery.
