(Threadfin breams, Whiptail breams)
Etymology: Nemipterus: Greek, nema, -atos = filament + Greek, pteron = wing, fin (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; non-migratory; depth range 8 - 110 m (Ref. 9785). Tropical; 34°N - 26°S, 76°E - 172°E (Ref. 3810)
Indian Ocean: Maldives (Ref. 30829), Gulf of Mannar, Sri Lanka, Andaman Sea, Strait of Malacca and northwestern Australia. Western Pacific: southern Japan to northeastern Australia. Most authors have incorrectly applied the name Nemipterus peronii to this species.
Length at first maturity / Size / Weight / Age
Maturity: Lm 16.6, range 13 - ? cm
Max length : 24.0 cm SL male/unsexed; (Ref. 48635); common length : 18.0 cm SL male/unsexed; (Ref. 3810)
soft rays: 7. Suborbital spine absent. Preopercle with 3 transverse scale rows. Pectoral fins moderately long, reaching to or just short of level of anus. Pelvic fins moderately long, reaching to or just short of level anus. A line drawn up from posterior edge of suborbital reaching the dorsal profile at about the origin of dorsal fin. Females predominate at small sizes while males dominate the larger size classes. Maybe a sequential hermaphrodite. Axillary scale present. Color: Upper body iridescent pink, silvery white below. Lower margin of caudal fin white.
Inhabits sandy and muddy bottoms; also in sheltered estuaries (Ref. 48635). Feeds mainly on crustaceans and small fishes. Principal catch in the Taiwanese pair-trawl fishery off the coast of northwestern Australia. Good food fish (Ref. 171).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Females predominate at small size classes while males dominate the larger size classes, and there is some evidence that this species is a sequential hermaphrodite.
