thermal requirements of fishes. Quarterly
Review Biology 31:75-81.
Temperature sets lethal limits to life; it
conditions the animal through acclimation to
meet the levels of temperature that would
otherwise be intolerable; it governs the rate
of development; it sets the limits of metabolic
rate within which the animal is free to perform;
and it acts as a directive factor resulting in
the congregation of fish within given thermal
xanges, or movements to new environmental
conditions. Some of the principles in this
multiple role of temperature are considered in
this paper. Lethal temperature limits are
given for Catostomus commersoni, Salvelinus
fontinalis, and Semotilus atromaculatus.
