Abstract

FROM observations based primarily on natural populations, Bourlière1 was able to present evidence that lowered environmental temperatures slow the rate of growth and prolong the life-span of various fishes, amphibians and reptiles. No experiments, however, have been carried out to test the effect of ambient temperatures on both growth rate and life-span in poikilothermic vertebrates under controlled laboratory conditions. For such experiments it is desirable to have populations of short-lived animals which show senescence, and thus “annual” fishes would be suitable test subjects2.
