TAXONOMY
Kingdom: Animalia
Phylum:  Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Suborder: Labroidei
Family: Embiotocidae (surfperches)

Genus/species: Rhacochilus vacca 

GENERAL CHARACTERISTICS: Above, dark gray or brown pigment with a silvery luster which dominates the color on sides and belly; darker blotches on the back and sides, dark vertical bars on juveniles; fins dusky deeply forked caudal fin.

Length 25–30 cm (10-12 inches); maximum 42 cm (16.5 in).

 

DISTRIBUTION/HABITAT: Alaska to north central Baja California, Mexico.  Rocky shores, pilings, kelp beds,  underwater structures to 46 m (150 ft).        

 PilePerchIMG_0091

DIET IN THE WILD: R. vacca feed on hard-shelled mollusks, crabs and barnacles. 

REPRODUCTION: Fertilization is internal. Viviparous (live bearer). Fecundity increases with age, averaging from 11–60 young.

LONGEVITY: 7–10 years.

CONSERVATION: Least Concern, the distribution of this species may coincide with a number of designated marine protected areas.

REMARKS: Specialized pharyngeal dentition enable the pile perch to crush hard shells persuading some ichthyologists to place the species in its own genus (Damalichthys).

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Family: Embiotocidae (Surfperches)

Genus/species: Amphistichus rhodoterus

 GENERAL CHARACTERISTICS: The body of the Redtail Surfperch is a deep oval shape and is compressed from side to side. All fins reddish or pink. Faded brown bars on the side. Silvery overall with pale olive shading above and 9 to 11 narrow vertical dark bars, posteriorly, broken and staggered along the lateral line. Caudal (tail) fin broadly forked; dorsal fin distinctive for the long dorsal spines that contrast with shorter soft rays.

Length up to: 41 cm (16 in) and 2.1 kg (4.5 lbs.) in weight.

 

DISTRIBUTION/HABITAT: Temperate marine. Vancouver Island to Monterey Bay around sand beaches and rocky shores in surf.

DIET IN THE WILD:  A. rhodoterus feeds on worms, crabs, other small crustaceans, and fishes.

LONGEVITY: Life span: up to 9 years.

REPRODUCTION: The Redtail Surfperch females are viviparous and reproductively mature at 3–4 years; males mature at 2 years. The females enter bays and estuaries to spawn.

REMARKS: This shallow water schooling surfperch is most often caught from central California northward.  A. rhodoterus omprises 10–30% of the total recreational catch in this area. Redtails also support a sizable commercial fishery, and comprise almost 75% of the commercial surfperch catch.

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

Genus/species; Sebastes miniatus

GENERAL CHARACTERISTICS: Caudal fin slightly indented. Dark red in color, sides mottled with gray; mouth and fins red, fins usually edged with black; 3 obscure stripes radiating from each eye. The mouth is large, with the lower jaw slightly projecting. On fish shorter than 12 inches, the mottling is much more apparent and the fins are often edged with black. The vermilion rockfish has scales on the bottom of the lower jaw which make it rough to the touch. Max length : 91.0 cm (36 inches).

Sebastes miniatus14785052061_ca258d6da6_o

DISTRIBUTION/HABITAT: Eastern Pacific: British Columbia, Baja California, Mexico. Marine; Adults inhabit shallow to deep rocky reefs at depths of 100 to 500 feet, (has been taken from depths as great as 900 feet).

DIET IN THE WILD: Smaller fishes, squid and octopus. Most fishes that are eaten are other smaller kinds of rockfish.

REPRODUCTION: Viviparous. As with all other rockfish, fertilization is internal and the young are mobile with the free-swimming young feeding primarily upon shrimp–like organisms.

REMARKS; Largest recorded in CA was 30 inches; Weight of at least 15 pounds. Largest taken off California by a recreational angler: 14 pounds, 9 ounces.

Color of Life note: Red color is the first to be filtered out as one depends deep into the ocean making this Vermillion rockfish hard to spot by predators.

Genus/pecies: Sebastes serriceps

 

TreefishIMG_8880GENERAL CHARACTERISTICS:  One of the most striking, unusually marked rockfishes, with black stripes over a yellow body and red lips and chin. Compact body with large head venomous spines.

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).

IMG_8885

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.

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.

Genus/species:   Sebastes nebulosus

 

GENERAL CHARACTERISTICS: Body blue or black, mottled with yellow; some individuals white ventrally; a broad yellow stripe from about the 3rd dorsal spine runs into or along the lateral line. Pelvic, anal and caudal fins are dark.Length to 45 cm (18 in), weight to 1.7 kg (3.75 lbs).

 DISTRIBUTION/HABITAT: Southeast Alaska to Southern California. Lives among rocky shores along exposed coasts to depths of 3–138 m (10-450 ft) . Lurk solitarily in caverns and among crevices, rest benthically on their fins. Often remain on their “homesite” for many years.

 DIET IN THE WILD: Preys upon fishes, crustaceans (including amphipods, crabs and shrimps), brittlestars and mollusks (including gastropods, squid and octopuses).

 REPRODUCTION: Fertilization internal.

MORTALITY: Can live to at least 79 years.

CONSERVATION: IUCN, Not evaluated.

REMARKS: One of the tastiest rockfishes, but infrequently in markets because rarely caught. All rockfishes have venomous spines on dorsal, pectoral and anal fins. Not so toxic as scorpionfishes venom, but still capable of inflicting a painful sting. Sebastes is Greek for “magnificent.” Nebulosus is Latin for “clouded.”
