Antioxidant Defenses in the Kidneys and Heart of the Freshwater Fish Astyanax lacustris Subjected to High (31°C) and Low (15°C) Temperatures.

ABSTRACT: Aquatic ecosystems have their abiotic and biotic factors constantly altered by various factors. Among them, water temperature is an abiotic factor that can significantly affect fish physiology, increasing energy demand, which can impact homeostasis and survival. Endocrine and metabolic changes and enzymatic modulation are referred to as stress responses, which can lead to oxidative stress, generating negative physiological effects when temperature limits are exceeded. Oxidative stress biomarkers used in combination can highlight the effects of a stressful condition. Here, we seek to understand how the species Astyanax lacustris, which is native to Brazil and has ecological and economic importance, as well as remarkable research potential, responds to changes in water temperature. Thus, we
