Efficiency of Pectoral-Fin Propulsion of Cymatogaster Aggregata

  • Paul W. Webb


The percid family Embiotocidae is one of the few groups of fish that employ non-caudal fin propulsion systems at high sustained swimming speeds. The fish use the pectoral fins (labriform mode) at low activity levels and caudal fin propulsion for burst activity. The 45-min Ucrit achieved by Cymatogaster aggregata swimming in this mode is comparable with that of other fish at similar activity levels (Webb (1973b)).
