Feeding Mechanisms and Trophic Interactions

Preview

The composition of the present-day California marine fish fauna is largely a reflection of trophic interactions. This chapter first organizes the subject of food and feeding in fishes into three parts and variously draws examples from members of the California marine fish fauna. It discusses factors that determine diet including body shape and feeding behavior, identifies types of food capture, and describes several kinds of feeding mechanisms. Second, it describes some of the major types of food items consumed by representative taxa of the California fauna and associate these taxa with standard trophic level designations. Third, it uses generalized profiles of trophic relationships to portray the main feeding interactions among fishes occupying bay-estuarine, inner and outer shelf, rocky intertidal, rocky reef and kelp bed, epipelagic, and deep midwater habitats.
