Hyperprosopon argenteum, the walleye surfperch, is a species of surfperch native to the eastern Pacific Ocean.
The body of the Walleye surfperch is oval and strongly compressed. The head is small and the eyes are large. The mouth is small and slanted downward. Its normal colouration is silver with faint dusky shading on the back, while the tips of the ventral fins, the borders of the anal fin, and the tail fin are black. The Walleye surfperch can be distinguished from other surfperch by the distinctive black tips on the ventral fins and black borders on the tail and anal fins. This species can reach a length of 30 centimetres (12 in) length.
Walleye surfperch are found in the Eastern Pacific Ocean from Vancouver Island, British Columbia, Canada to central Baja California, Mexico, including Guadalupe Island (off northern central Baja California).
Walleye surfperch live in the surf on sand beaches and over sand near rocks, they are often found and caught around piers. Mating takes place in October, November and December when the usual dense schools disperse with the males and females pairing off. The approach of another male is immediately countered by a quick charge from the courting male toward the intruder. Between 1 and 19 young, depending on the size of the mother, are born the following spring. They average a little over 1.5 inches in length at birth. They reach maturity the following fall and winter; in fact, the largest proportion of the breeding population appears to be young of the year. Walleyes are probably short-lived as are most other surfperches. A 10.5 inch walleye was only 6 years old. Walleye surfperch often occur in dense schools. They feed on small crustaceans. They are viviparous with the females giving birth to live young. They are an important game fish.
Walleye surfperch can be plentiful, easy to catch and occur in large numbers in surf, shore and pier catches.
The yellow perch, commonly referred to as perch, striped perch, American perch,American river perch or preacher is a freshwater perciform fish native to much of North America. The yellow perch was described in 1814 by Samuel Latham Mitchill from New York. It is closely related, and morphologically similar to the European perch ; and is sometimes considered a subspecies of its European counterpart. Other common names for yellow perch include American perch, coontail, lake perch, raccoon perch, ring-tail perch, ringed perch, and striped perch. Another nickname for the perch is the Dodd fish.
Grunion are two fish species of the genus Leuresthes: the California grunion, L. tenuis, and the Gulf grunion, L. sardinas. They are sardine-sized teleost fishes of the New World silverside family Atherinopsidae, found only off the coast of California, USA, and Baja California, Mexico, where the species are found on both the Pacific Ocean and Gulf of California coasts. Many people enjoy catching grunion at events called "grunion runs."
The gafftopsail catfish is found in the waters of the western central Atlantic Ocean, as well as the Gulf of Mexico and the Caribbean Sea. It has long poisonous spines which can cause painful wounds. It feeds on crustaceans and other fish. The male of the species fertilizes the eggs of the female, and broods them in his mouth until they hatch. The gafftopsail feeds throughout the water column. This fish is a common catch in the Southeastern US, although it may be found as far north as New York. They are considered strong fighters by anglers. They are taken from piers, jetties, reefs, and the surf, as well as bottom fishing or flats fishing. They are caught with hard lures as well as soft plastics, cut bait, and live or dead shrimp. Some fishermen use traps for catfish, a method regulated by some states.

The California corbina is marine demersal fish in the croaker family. It can often be found along sandy beaches and in shallow bays. This species travels in small groups along the surf zone in a few inches of water to depths of 20 meters (66 ft). Other names include "California kingcroaker," "California whiting," and "kingfish".
Spotfin croaker is a species of croaker occurring from Mazatlán, Mexico, to Point Conception, California, including the Gulf of California. It is the only species in the genus Roncador. In California, they are most commonly found south of Los Angeles Harbor. They live along beaches and in bays over bottoms varying from coarse sand to heavy mud and at depths varying from 4 to 50 feet or more. They prefer depressions and holes near shore.
The blackspot shark is a small species of requiem shark in the family Carcharhinidae found in the tropical Indo-West Pacific Ocean between latitudes 24°N and 30°S, from the surface to a depth around 40 m (130 ft). Its length is a little under one meter (yard) and it is not considered to be dangerous to humans. It feeds mainly on fish, crustaceans, and squid. This shark is also caught in small-scale fisheries for human consumption.
The spined pygmy shark is a species of squaliform shark in the family Dalatiidae found widely in all oceans. Growing no larger than roughly 28 cm (11 in), it is one of the smallest sharks alive, with this record beaten by the dwarf lanternshark. This shark has a slender, cigar-shaped body with a sizable conical snout, a long but low second dorsal fin, and an almost symmetrical caudal fin. Its sister species S. aliae and it are the only sharks with a spine on the first dorsal fin and not the second. Spined pygmy sharks are dark brown to black, with numerous bioluminescent organs called photophores on their ventral surface. The shark is believed to use these photophores to match ambient light conditions, which break up its silhouette and help the shark to avoid being seen by predators below.
The blurred lanternshark is a little-known species of dogfish shark in the family Etmopteridae, found around the world in benthic and pelagic habitats from a depth of 110 m (360 ft) to over 1 km (0.62 mi) down. This shark forms the E. pusillus species group with the smooth lanternshark, which are distinguished from other members of its family by having irregularly arranged, flat-topped dermal denticles that give them a "smooth" appearance. Both species are slender-bodied with long heads, two dorsal fins bearing spines, no anal fins, and light-emitting photophores. The blurred lanternshark is larger, reaching 67 cm (26 in) or more in length. This species feeds on small squid, fishes, and fish eggs, and is ovoviviparous. It has been assessed as of Least Concern by the International Union for Conservation of Nature, because of its wide distribution and lack of threat from fishing pressure.
The peppered catshark is a common but little-known species of catshark, part of the family Scyliorhinidae, inhabiting depths of 130–1,326 m (427–4,350 ft) in the northern Gulf of California. It is found on or near the ocean floor, and conducts seasonal migrations, spending winter in deeper water. Reaching a length of 37 cm (15 in), this species has a slender grayish body with a fine covering of black dots. On the dorsal edge of its caudal fin is a prominent crest of enlarged dermal denticles. It is oviparous, with the reproductive period probably lasting from May to September. The International Union for Conservation of Nature (IUCN) has listed the peppered catshark under Least Concern, as it faces no significant threats from human activity.
Paralabrax clathratus, the kelp bass, bull bass or calico bass, is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae, classified as part of the family Serranidae which includes the groupers and anthias. It is found in the eastern North Pacific Ocean where it is an important species for both recreational and commercial fisheries.

This species can reach a length of 43 centimetres (17 in) TL though most do not exceed 30 centimetres (12 in) TL. The maximum recorded weight is 2.0 kilograms (4.4 lb). Like other surfperches, it gives birth to live young. The diet of the barred surfperch consists predominantly of sand crabs .
According to the California Department of Fish and Game, Barred Surfperch can be identified by bars and spots on sides which are often unbarred, as well as the absence of red tail.
