TAXONOMY

Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family:Embiotocidae (Surfperches)
Genus/ species Cymatogaster aggregata
GENERAL CHARACTERISTICS Shiner surfperch are small, deep-bodied fish, silvery colored with rows of dark spots on the scales that form vague black stripes on sides crossed by three vertical yellow bars. Males cover their shiny silver and yellow stripes with a darker courtship colors during the summer. Their length is to 20 cm. (8 inches).
DISTRIBUTION AND HABITAT Shiners are found from Wrangell, Alaska to Baja California. Within their range, they are a common fish in shallow water around eelgrass beds, piers, pilings and oil platforms, and are also found in calm, shallow waters along the coast. They live in loose schools to depths of 146 m (480 ft). They are also known to enter brackish and fresh waters, and are common in San Francisco Bay.
DIET IN THE WILD Their diet includes small crustaceans, crab larvae, and polychaete worms, as well as planktonic copepods, amphipods, fish eggs, algae and diatoms.
PREDATORS These small fish are preyed upon by other fishes, including kelp bass, sand bass, and halibut as well as by harbor seals. They are caught along almost all shoreline fishing areas, probably the most common fish taken by recreational anglers along the California coast and in estuaries.
REPRODUCTION: Shiner surfperch mate during the summer; young are born the following spring or summer. Fertilization is internal, embryos are nourished internally, and females give birth to about 20 live young. Litter size varies from 4 to 25. Some males are sexually active immediately after their birth. Females grow faster than males. Their live span is at least six to eight years.

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Pomacanthidae (Angelfishes)
Genus/species: Holacanthus tricolor
GENERAL CHARACTERISTICS: Like their close relatives the butterflyfishes, they have a deep, laterally compressed body, a single and a unnotched dorsal fin. The most observable difference between the two families is the long spine at the corner of the preopercle common to angelfishes.
H. tricolor has a yellow anterior body with the remaining parts of body black. The caudal fin is entirely yellow.
Maximum length of approximately 12 inches (35 cm)
DISTRIBUTION/HABITAT: Western Atlantic: Georgia (USA), Bermuda, and northern Gulf of Mexico to Santa Catarina, Brazil among rock jetties, rocky reefs and rich coral areas.
Depth range 3 - 92 m (10-300 ft)
DIET IN THE WILD: Feeds on tunicates, sponges, zoantharians and algae.
REPRODUCTION/DEVELOPMENT: Pair bonding suggests a monogamous relationship. Pairs usually consist of one small and one large fish. They will spawn by slowly rising up in the water column while bringing their bellies close together, and releasing large amounts of eggs and sperm. A female can release anywhere from 25 to 75 thousand eggs each evening. This can total as many as ten million eggs for the duration of the spawning cycle. The eggs are transparent and pelagic, floating in the water column hatching in 15 to 20 hours becoming "pre-larval" angelfish attached to their large yolk sac with no functional fins, no eyes, or gut. After about 48 hours the yolk is absorbed developing into true larvae feeding on plankton. Growth is rapid and 3 to 4 weeks after hatching the fish will reach about 15-20 mm (0.6-0.8in) and will settle on the bottom.
CONSERVATION: IUCN, Least concern
REMARKS: Reports of ciguatera poisoning .
