Comparisons of Critical Thermal Maxima and Minima of Juvenile Red Drum (Sciaenops ocellatus) from Texas and North Carolina
The Texas Parks and Wildlife Department was Interested In Identifying cold-tolerant red drum (Sciaenops ocellatus) for a supplemental bay stocking program to help prevent massive fish kills when winter temperatures drop to potentially dangerous levels. Critical thermal maxima (CTMax) and minima (CTM...
