Barred Surfperch

(Amphistichus argenteus)
Population status in the wild: Least concern

The Barred Surfperch is a coastal fish species that belongs to the family Embiotocidae. Found along the Pacific coast of North America, particularly from California to Baja California, these fish thrive in sandy, rocky, and kelp-covered areas of surf zones, often in shallow waters ranging from intertidal zones to depths of around 50 feet. The species is recognized by its distinct pattern of dark bars running horizontally across its silver body, which gives it its name. Barred surfperch are medium-sized fish, typically reaching lengths of 12 to 18 inches, though some individuals may grow larger.

Barred surfperch are primarily herbivores and omnivores, feeding on a varied diet that includes small invertebrates, algae, and plankton. They are well-adapted to life in the surf, where they use their powerful, laterally compressed bodies to navigate through turbulent waters. Their large, pectoral fins allow them to maintain stability in rough conditions, and they are capable of swift, darting movements to escape predators or capture prey.

These fish are generally solitary or form small groups, though they can sometimes be seen in larger aggregations, particularly during spawning seasons. They are viviparous, meaning they give birth to live young rather than laying eggs, with females giving birth to several small fish after a gestation period of about a year. The young surfperch are often found in sheltered, shallow areas, where they grow rapidly before moving into deeper waters as they mature.

Barred surfperch are important members of the coastal food web, serving as prey for a variety of predators, including sea birds, sharks, and larger fish. While not typically targeted by commercial fisheries, they are popular among recreational anglers, who value them for their challenging catch and good taste. Despite their somewhat humble status in the fishing world, they play a critical role in maintaining the health of coastal ecosystems.

Fun Facts:
Barred surfperch are excellent swimmers, using their large pectoral fins to glide effortlessly through the surf.

Their live birth method is a unique trait in many fish species, and their young are highly developed at birth, capable of swimming immediately.

They are known to be able to survive in brackish water and can adapt to varying salinity levels, making them resilient in dynamic coastal environments.
