The green jobfish Aprion virescens is a species from the snapper family that frequents tropical reefs throughout the Indo-Pacific. Their long torpedo shaped body and pale green colouration is unmistakable underwater. They are prolific predators and are most often found cruising mid-water directly above coral and rocky reefs.
DISTRIBUTION: Indo-Pacific: East Africa to the Hawaiian Islands, north to southern Japan, and south to Australia
HABITAT: Adults and juvenile jobfish inhabit open waters of deep lagoons, channels, or inshore reef areas, from the surface down to 100m
BIOLOGY: A relatively long lived species, which can live to 16 years. Sexes are separate with no evidence of sex change and reproduction occurs externally via egg scattering in the water column. Sexual maturity is reached at 70 cm. The maximum body size recorded is 112 cm and the maximum weight reported is 16-20 kg. Green jobfish are diurnal predators, feeding mainly on fish, crustaceans and cephalopods.
MOVEMENT: Recorded to be seasonally resident within large core areas. Highly reef-associated in South Africa.
BEHAVIOUR: A curious species that will come in to investigate scuba divers. However, high diving activity can make them wary and elusive. Usually seen singly, but also in groups.
CONSERVATION STATUS: Currently categorised as “least concern” on the IUCN Red List of Threatened Species. However, recent research has indicated that this species is vulnerable to localised depletion by fishing due to its resident nature.
