Immature largemouth bass were collected by seining from Par Pond Reservoir, taken to the laboratory, and slowly acclimated at temperatures of 20, 28, and 36$sup 0$C. At 36$sup 0$C none of the fish survived the one week acclimation period. Mortality rates of fish acclimating at lower temperatures were significantly less. The critical thermal maximum of each bass was determined by observing the point at which the fish lost its sense of orientation and equilibrium. Allele frequencies were essentially the same among fish surviving the acclimation process as in the parental population. (HLW)
