Aprion virescens (Valenciennes 1830)

Genus: ,

Scientific Name: Aprion virescens

English Name: Green jobfish

Creole Name: Zob gri

French Name: Vivaneau job

IUCN Red List Status: Least Concern (LC)

Description:

Dorsal spines: 10; Dorsal rays: 11; Anal spines: 3; Anal rays: 8.

Long torpedo-shaped body with forked caudal fin. Body greenish or bluish grey darker dorsally lightening ventrally. Large diamond-shaped scales on body, those on back parallel with lateral line.

Basal portion of 5 posterior spinous dorsal membranes with dark blotches. Head moderately elongate with relatively blunt snout with prominent groove in front of eye. Distinct canines in front of jaw.


Size:

Maturity: Lm 44.9 cm FL. Range unknown: 42-50cm FL. Max Length 112cm TL.

(The max size of 112cm TL was reported from Seychelles (de Moussac 1988). The maturity ranges described above are from a Hawaiian study. Research in Seychelles indicates and Lm50 at over 60cm TL (de Moussac 1988, MRAG 1995). 


Habitat and Ecology:

Adults inhabit open waters of deep lagoons, channels, or seaward coral and rocky reefs (depth 0-180m). Solitary or in small groups. Feeds on fishes, crabs, shrimps and cephalopods.


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the hand line fishery, it is a common and often abundant component of the catch. A minimum catch size has been proposed under the new demersal fishery plan but has yet to be promulgated. 

On the 6th of February 2020 the provsions of the Mahe Plateau trap and line fishery were gazetted and became law. This included a minimum retention size for Aprion virescens of 32cm Fork Length (FL). It is to be noted that this size is below the Lm50 (i.e. mean size at maturity) for the species and that this therefore is an interim measure until such time as Phase 2 of the plan identifes the local Lm50 for the species.
