The Effect of Different Acclimation Temperature on Oxidative Muscle Proportions of the Tilapia Oreochromis mossambicus

Abstract:

This study investigated the effect of acclimation temperature (16, 25, 30 and 35ºC) on oxidative muscle proportions of yolk-sac larvae, feeding larvae and fry stages of the tilapia Oreochromis mossambicus. Over the thermal range tested, the proportions were highest for the yolk-sac stage and significant decline occurred in feeding larvae. The proportions were significantly higher for the fry stages at 16, than at 25, 30 and 35ºC. Changes in oxidative muscle proportions and succinic dehydrogenase activity at different acclimated temperatures may explain the positive compensation of oxidative metabolism in O. mossambicus myotomal during different developmental stages.
