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

Genus/species:   Sebastes nebulosus

GENERAL CHARACTERISTICS: Body blue or black, mottled with yellow with some individuals being 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 up 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). S. nebulosus lurks solitarily in caverns and among crevices, resting  benthically on their fins. They 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 it is 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.”

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.
