More Info


Distribution

Known in Australian waters from northwestern Australia (Ningaloo Reef to Rowley Shoals, Scott Reef and Ashmore and Cartier Islands in the Timor Sea) and from the northern Great Barrier Reef, Queensland to about Wooli, New South Wales. Also at Lord Howe Island and Middleton Reef, Christmas Island and Cocos (Keeling) Island.

Elsewhere widespread in the Indo-west-central-Pacific from the Red Sea and East Africa to the Tuamotos and Hawaii. 

Green Jobfish are often solitary, although they may occur in small groups. They usually prefer the open waters of reef channels, outer slopes, dropoffs and deep lagoons, in depths of 2-180 m.

Features

Meristic features:
Dorsal-fin spines/rays: X, 11
Anal-fin rays: III, 8

Preopercle edge smooth or sometimes denticulate in juveniles, and a distinct horizontal groove in front of eye. Dorsal and anal fins without scales. Scale rows on back parallel with lateral line.

Colour

Dark greenish to bluish or bluish-grey, fading to white below. Bases of five posterior dorsal-fin spines with black patches.

Feeding

Carnivore - feed mostly on fishes, crabs, shrimps and cephalopods.

Fisheries

Green Jobfish are commercially important throughout their range, and are also a popular sports fish. Usually marketed fresh, but also dried and salted. Green Jobfish are excellent eating, although large individuals may cause ciguatera poisoning.
