Pristipomoides filamentosus, also known as the crimson jobfish, rosy snapper, bluespot jobfish, crimson snapper, king emperor, king snapper or rosy jobfish, is a species of

commercial fisheries and is sought out as a game fish--one of the Deep Seven
species of Hawai'i.

Taxonomy

Pristipomoides filamentosus was first formally

zoologist Achille Valenciennes with the type locality given as Saint-Denis on Réunion.[3] The specific name filamentosus means "filamentous" and refers to the filament-like last soft rays in the dorsal and anal fins.[4]

Description

Pristipomoides filamentosus has an elongated, robust body with a depth of roughly a third of its

total length of 100 cm (39 in), although 50 cm (20 in) is more typical, and a maximum published weight of 8.2 kg (18 lb).[2]

Distribution and habitat

Pristipomoides filamentosus has a wide

larvae have been recorded as far south as Sydney. It also occurs at Lord Howe Island in the Tasman Sea.[6] It is a benthopelagic species[2] which is found at depths between 40 and 360 m (130 and 1,180 ft) over rocky substrates and rocky reefs.[1]

Biology

Pristipomoides filamentosus is a nocturnal feeder, migrating upwards through the water column to the part of its habitat closest to the surface to prey on small fishes,

salps. In the Seychelles spawning occurs between October and April, reaching its peak from February to April and again in November, while in Hawaii, it takes place between March and December, peaking from May to September.[1] This is a slow growing long lived species[6] with the oldest fish recorded at 44 years old.[2]

Parasites

Known parasites of the crimson jobfish include the

isopod Anilocra gigantea,[7] the pennellid copepod Lernaeolophus sultanus and the nematodes Cucullanus bourdini[8] and Raphidascaris (Ichthyosaurus) eteligis.[9]

Fisheries

Pristipomoides filamentosus is an important species for fisheries and is caught using bottom longlines and deep handlines to be, largely, sold as fresh fish. The flesh is considered to be of good quality. It is of high commercial value in Hawaii and is the second most important quarry for the offshore handline fishery, making up 20% of the total catch of

bottomfish.[1]

According to the

FAO, the fish have been overexploited in the Seychelles, but the stock is recovering. The commercial capture of crimson jobfish sharply dropped to 4,400 tonnes in 2009 from 25,300 tonnes the previous year.[10]

In Hawaii, it is known as opakapaka and is reported to be the most desirable species of snapper for eating, with moist, white flesh. The peak fishing season in Hawaii runs from October to February.[11]
