Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Scorpaeniformes (Scorpionfishes and flatheads)
Family: Sebastidae (Rockfishes, rockcods and thornyheads)

Genus/species: Sebastes serriceps

GENERAL CHARACTERISTICS:  One of the most striking, unusually marked rockfishes, with 5-6 black bars over a yellowish to olive body and red lips and chin. Compact body with large head venomous spines.

NOTE: Other barred rockfishes are not yellow or olive.


DISTRIBUTION/HABITAT:  San Francisco to central Baja California Inhabiting areas with numerous caves, crevices and other protective recesses. They are solitary and territorial and usually found between 6–40 m (19-125 ft) a maximum depth of 45 m (190 ft).

DIET IN THE WILD: Most probably either crepuscular (feeding at dawn and dusk) or nighttime ambush predator, feeding on shrimp, crabs and small fishes.

REPRODUCTION: Viviparous, same as other Sebastes sp.

PREDATORS: Sharks, dolphins, and seals.

LONGEVITY: Live up to 25 years

REMARKS: S. serriceps is an important species in both the nearshore recreational fishery and in the commercial live fish fishery.

Serriceps means “saw head” in latin, referring to the large head spines. See below on this immature Treefish.

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Scorpaeniformes (Scorpionfishes and flatheads)
Family: Sebastidae (Rockfishes, rockcods and thornyheads)

Genus/species: Sebastes pinniger

GENERAL CHARACTERISTICS: The Canary Rockfish is bright yellow to orange mottled on a light gray background with 3 orange stripes across head and orange fins. The Lateral line is in a clear area. The pectoral, pelvic, and anal fins are moderately pointed and are large.

Length up to 76 cm (2.5 ft)


DISTRIBUTION/HABITAT: They are found from Alaska to Baja California, Mexico.
S. pinniger adults hover in loose groups above rocky bottoms at average depths of 80–200 m (264-660 ft).

DIET IN THE WILD: They feed on small fishes and krill.

REPRODUCTION: they are mature at 14 in (36 cm) or 5-6 years old., Fertilization: Internal fertilization, ovoviviparous

LONGEVITY: Up to 75 years

Minimum population doubling time 4.5 – 14 years. Various state restrictions on fishing have been put in place over the years, including banning retention of canary rockfish in Washington in 2003. Because this species is slow-growing, late to mature, and long-lived, recovery from these threats will take many years, even if the threats are no longer affecting the species.

REMARKS: The Vermillion Rockfish which is similar is more reddish and the lateral one is not in the grey zone.

Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Family: Embiotocidae (surfperches)                

Genus/species: Embiotoca jacksoni                           

 GENERAL CHARACTERISTICS:  Their body is deep and compressed.Their colors are various shades of brown, red, green above, yellowish below, darker bars on sides with a blue bar on base of anal fin. Note a mustache-like black bar on upper lip.  

Length up to 39 cm (15 in)


DISTRIBUTION/HABITAT; Black Surfperch are found from Fort Bragg, California to Punta Abreojos, Baja California, Mexico nearshore reefs and kelp forests. They are also found over sand, and in estuaries near algae.

Usually within 1 m (3 ft) of the substrate.

DIET IN THE WILD: E. jacksoni  feed on worms, crustaceans and mollusks. They are also cleaner fish of conspecifics as well as other species.

REPRODUCTION: Summer is the peak breeding season. Fertilization is internal. Viviparous; young embryos are nourished internally and are quite large as newborns.

PREDATORS: Leopard sharks

CONSERVATION: Not evaluated

REMARKS: The species name jacksoni, is after A.C. Jackson, who, in the 19th century, first noted that surfperches gave birth to live young.  Fertilization is also internal as it is in Rockfishes.
