Critical thermal maxima and minima for curimbatá, Prochilodus scrofa Steindachner, of two different sizes

Aquaculture Research, 1995
Critical thermal maxima (CTMax) and minima (CTMin) were determined for Prochilodus scrofa Steindachner of two sizes (19.5 ±7.2 g and 249 ± 42.4 g). acclimated at 15. 20, 25, 30 and 35 ± 1°C. The CTMax and the CTMin for the smaller fish were 33.9. 36.7. 38.7, 40.3. 42.0°C and 5.0, 7.2. 9.2. 10.3. 13.4oC and for the larger (Ish 33.3, 35.7, 38.2. 40.6. 42.
