Tilapia death timing is closely related to the strain of tilapia. One strain dies a few degrees below 60F. As the temperature drops below 56F toward 45F more and more different strains of tilapia die. Last ones to die are those of the pure strain of blue tilapia who die at 45F. Now - few if any places sell the absolute pure strain of blue tilapia. Most of the tilapia you buy now are some sort of mixed hybrid. Know the death temperature for the tilapia you buy regularly.
