(Threadfin breams, Whiptail breams)
Etymology: Nemipterus: Greek, nema, -atos = filament + Greek, pteron = wing, fin (Ref. 45335).
Environment / Climate / Range
Marine; demersal; non-migratory; depth range 5 - 80 m (Ref. 9785). Tropical; 34°N - 11°S, 31°E - 133°E (Ref. 3810)
Length at first maturity / Size / Weight / Age
Maturity: Lm 14.0  range ? - ? cm
Max length : 32.0 cm TL male/unsexed; (Ref. 3836); common length : 25.0 cm TL male/unsexed; (Ref. 5450); max. published weight: 596.00 g (Ref. 1448); max. reported age: 8 years (Ref. 1448)
soft rays: 7. Eleven to twelve pale golden-yellow stripes along body from behind head to base of caudal fin. A prominent red-suffused yellow blotch below origin of lateral line. Pectoral fins very long, reaching to or just beyond level of origin of anal fin. Caudal fin moderately forked, upper lobe slightly longer than lower and produced into a short or moderately long filament. Three transverse scale rows on preopercle. Axillary scale present. Color: Upper body pinkish, silvery below.
Indo-Pacific. A report on Nemipterus japonicus as a Red Sea immigrant into the Mediterranean is unconfirmed (Ref. 3810), however it has recently (2005) been reported from Haifa Bay (Ref. 72453). Likewise, a record of this species from northwestern Australia is unfounded.
Very abundant in coastal waters, found on mud or sand bottoms, usually in schools. Feeds mainly on small fishes, crustaceans, mollusks (mainly cephalopods), polychaetes and echinoderms. Marketed mainly fresh, but also frozen, steamed, dried-salted, dry-smoked, fermented or made into fish balls and fish meal.
