Abstract

Little is known about the swell shark, Cephaloscyllium ventriosum, beyond that they are common in shallow waters from Chile to Monterey Bay, including the Sea of Cortez. In order to address this lack of knowledge, I am studying the ecology and life history of the swell shark. Individuals were collected using gill nets at seven stations along the Southern California coast and three stations at Catalina Island. The gill nets were set overnight in both April and July. Measurements were made of several characters to allow for age and growth as well as allometry studies. Along with these measurements, the stomach and an anterior section of the backbone were collected for later analysis. The vertebrae collected from the backbone samples will be stained with silver nitrate to allow the age of the individual to be determined. All of this information will be incorporated with catch data from the Ocean Resource Hatchery Enhancement Program (ORHEP) to develop knowledge of the ecology and life history of the swell shark.
