Etymology: Lutjanus: Malay, ikan lutjan, name of a fish.
Environment / Climate / Range
Ecology
Marine; brackish; reef-associated; depth range 12 - 100 m (Ref. 55). Tropical, preferred 27°C (Ref. 107945); 33°N - 33°S, 43°E - 178°W
Indo-West Pacific: Persian Gulf and Arabian Sea to Fiji, north to southern Japan, south to Australia. This species has been frequently misidentified as Lutjanus sanguineus (Ref. 55). There are unsubstantiated reports of this species from off East Africa.
Length at first maturity / Size / Weight / Age
Maturity: Lm 57.6, range 54 - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 55); common length : 50.0 cm TL male/unsexed; (Ref. 55); max. published weight: 7.9 kg (Ref. 4699); max. reported age: 31 years (Ref. 46527)
Adults inhabit both coastal and offshore reefs. They tend to be associated with sponge and gorgonian-dominated habitats on the North West Shelf (Ref. 28006), and hard mud areas of the Arafura Sea. In Australia, they frequently form mixed shoals with L. erythropterus. Juveniles tend to inhabit shallow inshore waters and larger fish live in deeper waters (Ref. 27260, 27264). Feed mainly on fishes, with small amounts of benthic crustaceans, cephalopods and other benthic invertebrates (Ref. 6390). They forage mostly at night (Ref. 6390). Marketed fresh, dried-salted (Ref. 55) and frozen (Ref. 9987).
Are batch or serial spawners (Ref. 28009).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.01320 - 0.01735), b=2.98 (2.95 - 3.01), in cm Total Length, based on LWR estimates for this species (Ref.
93245).
Trophic Level (Ref.
69278): 4.5 ±0.5 se; Based on diet studies.
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (K=0.12-0.18; tmax=12; Fec=5,000,000).
Prior r = 0.49, 2 SD range = 0.19 - 1.29, log(r) = -0.71, SD log(r) = 0.48, Based on: 2 M, 12 K, 3 tmax, 2 Fec records
Vulnerability (Ref.
