THE EFFECT OF TEMPERATURE UPON THE GROWTH OF LABORATORY-HELD POSTLARVAL PENAEUS AZTECUS

Abstract
Growth of postlarval brown shrimp, P. aztecus, in the laboratory increased with temperature from 15[degree] to 32.5[degree]C. Maximal growth increases per unit of temperature were observed in the temperatures above 20[degree]C. Survival in the laboratory decreased markedly at 32.5[degree]C and no animals survived at 35[degree]C. Tolerance to temperatures decreases above 30[degree]C. Population production in the laboratory appears to be optimal at temperatures of 22.5[degree] to 30[degree]C.
