Variation in metabolic enzymatic activity in white muscle and liver of blue tilapia, Oreochromis aureus , in response to long-term thermal acclimatization.

YOUNIS, Elsayed M. . 2015

The effects of rearing temperature on white muscle and hepatic phosphofructokinase (PFK),
pyruvate kinase (PK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST) and alanine
aminotransferase (ALT) were examined in fi ngerlings of blue tilapia, Oreochromis aureus . The experiment
was conducted for 14 weeks at temperatures of 18, 22, 26, 30, and 34°C. The activity of the glycolytic
enzymes PFK, PK, and LDH in white muscle increased signifi cantly with increase in water temperature.
A reverse trend was observed for these enzymes in the liver, except for LDH, which behaved in the same
manner as in white muscle. Cytosolic AST and ALT activity increased in both white muscle and liver in
response to warm thermal acclimatization, while a reduction in mitochondrial AST and ALT activity was
noticed at high temperatures in comparison with those at a lower temperature.
