Lutjanus gibbus

Paddletail snapper LJG
Characteristic features:

Reddish to greyish. Juveniles with blackish caudal peduncle and dark caudal fin with yellow outer margin.


Up to 50 cm TL.


Indo-West Pacific in tropical waters.


Coral reefs, from 1 to 150 m depth.


Feeds primarily on fishes, but also crustaceans, cephalopods and echinoderms. Juveniles occur in seagrass beds and sheltered shallow reefs. Subadults often form large schools which are mostly inactive during the day. Adults occur at greater depths along coastal slopes, sometimes forming large aggregations.1 Based on unsexed specimens, this species matures between a size range of 24.4 and 25.9 cm TL and at an age range of 2–4 years.2 In waters of Japan spawning has been observed to occur from May to October.3 male Paddletail snapper grow to a larger size than females.3 A preliminary study of Paddletail snapper in Indonesian waters found this species is faster growing and has a shorter lifespan (maximum recorded age of 9 years) when compared to populations elsewhere.4 In the waters of Japan, estimated maximum ages are 21 and 24 years for females and males, respectively.3

Indonesian fisheries:

Caught mainly with handlines, traps and gill nets.

Similar species:

A distinct species easily recognisable by its forked caudal fin with rounded lobes. Not likely to be confused with other species.
