Changes in the fatty acid composition and regulation of antioxidant enzymes and physiology of juvenile genetically improved farmed tilapia Oreochromis niloticus (L.), subjected to short-term low temperature stress

We evaluated the effect of cold shock on the fatty acid composition, antioxidant enzymes, and physiological responses of genetically improved farmed tilapia (GIFT). Experimental GIFT tilapia, a warm-water teleost, were initially acclimated at 28 °C and then transferred directly to 13 °C. Stress responses were monitored for 120 h. There was a significant change in all parameters in response to the cold stressor (P<0.05). Serum cortisol levels...
