Abstract

Tunas are extensively distributed throughout world's oceans and grow and reproduce fast enough to support one of the world's largest commercial fisheries. Yet they are apex predators living in the energy depauperate pelagic environment. It is often presumed that tunas evolved their specialized anatomy, physiology, and biochemistry to be capable of(a) high maximum swimming speeds, (b) high sustained swimming speeds,and/or (c) very efficient swimming; all of which help account for their wide distribution and reproductive success. However, a growing bodyof data on the energetics and physiological abilities of tunas do notsupport these assumptions. The three things demonstratively ''high performance'' about tunas, and probably other pelagic species such as marlin (Makaira spp. and Tetrapturus spp.) and dolphin fish (Coryphaena spp.), are (a) rates of somatic and gonadal growth, (b) rates of digestion, (c) rates of recovery from exhaustive exercise (i.e., clearance of muscle lactate and the concomitant acid load). All of these are energy consuming processes requiring rates of oxygen and substrate delivery above those needed by the swimming muscles for sustained propulsionand for other routine metabolic activities. I hypothesize that the ability of high performance pelagic species (tunas, billfishes, and dolphin fish) to deliver oxygen and metabolic substrates to the tissues athigh rates evolved to permit rapid somatic and gonadal growth, rapid digestion, and rapid recovery from exhaustive exercise (abilities central to success in the pelagic environment), not exceptionally high sustained swimming speeds.
