Bococcio Rockfish

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii (ray-finned fishes)

Order: Scorpaeniformes (Scorpionfishes and flatheads)

Family: Sebastidae (Rockfishes, rockcods and thornyheads)

 

Genus/species: Sebastes paucispinis

 

GENERAL CHARACTERISTICS: The long jaw which extends to the eye socket is distinctive. Adults’ backs range in color from olive- to burnt-orange with pink & red stomachs. Juveniles are light bronze with small brown spots on their sides. Coloring darkens and spots disappear as they mature.

 

World record: 90 cm (35 in), 9.5 kg (20 lbs)

 

DISTRIBUTION/HABITAT: Found from Alaska to Baja California in almost all habitats. Bocaccio rockfish from age 1 – 3 years are relatively pelagic becoming more demersal (bottom oriented) as they age. Oil platforms are now a somewhat important artificial habitat for the species.

 

Depth: 40 – 300 m (130 – 980 ft)

 

DIET IN THE WILD:The Bocaccio Rockfish is a voracious carnivore of other fishes including rockfishes.

 

REPRODUCTION:. Maturity occurs at 4–5 years of age. S. paucispinis are viviparous like all rockfishes, with internal fertilization and embryo development. Females give birth to live larval young.

 

LONGEVITY: up to 30-50 years.

 

PREDATORS; Seabirds feed on juveniles. Marine mammals are common predators of adults.

 

CONSERVATION: IUCN; Critically Endangered due to overfishing using trawling and gill netting which was curtailed in 1998. Because the species is slow-growing and late maturing, recovery will take many years. These fish are still being caught as bycatch in other fisheries.

 

REMARKS: Great sport fish, good eating. Like many rockfish species, the spines of Bocaccio can be mildly poisonous and cause unpleasant pain if you are unlucky enough to get poked by one!
