Erythrocyte nuclear abnormalities and leukocyte profile in the Antarctic fish Notothenia coriiceps after exposure to short- and long-term heat stress

Several studies suggest that Antarctic endemic stenothermic fish species, such as Notothenia coriiceps, have a limited ability to acclimate to warmer conditions. In the present study, we evaluated the effects of exposure to short- and long-term temperature increases on the occurrence of erythrocytic nuclear abnormalities (ENAs) and changes in the leukocyte profile of N. coriiceps. For the experiments, 30 specimens of N. coriiceps were captured …
