Heat Resistance and Thermal Acclimation Rate in Tropical Tetra Astyanax bimaculatus of Venezuela

Environmental Biology of Fishes, 2000
Venezuelan river tetra, Astyanax bimaculatus juveniles of 34.1–36.7 mm standard length and 0.83–1.0 g wet weight were acclimated for four weeks to 24–33°C, which are approximate average minimum and maximum river temperatures throughout the year. The fish acclimated to 24, 27, 30, and 33°C were exposed for 10 000 minutes at 35, 36, 37, 38, and 39°C to ...
