Abstract : Species profiles are literature summaries of the taxonomy, morphology, range, life history, and environmental requirements of coastal aquatic species. They are designed to assist in environmental impact assessment. Pile perch, striped seaperch, and rubberlip seaperch are popular sport fishes along the entire California coast. They are relatively common near wharves, pilings, jetties, and other nearshore structures. All members of this family are viviparous. Fecundity is positively correlated with size and age of the female. The young are released as miniature adults. All three species are relatively large for the family and may live 7 to 10 years. The primary prey items of all three species are various invertebrates; however, pile perch tend to prefer hard-shelled prey. The habitats of the three species overlap considerably. Little is known of their environmental tolerances.
