Thermal fluctuations significantly influence freshwater fish physiology and survival, particularly under climate change scenarios. This study investigates the molecular characterization of stress-responsive genes in selected freshwater fish species exposed to controlled temperature variations. Gene expression profiling using quantitative PCR identified differential regulation of heat shock proteins, antioxidant enzymes, and metabolic regulators. Results indicate temperature-dependent modulation of stress pathways, highlighting adaptive mechanisms and potential biomarkers for thermal resilience. Findings contribute to understanding fish responses to environmental stress and conservation strategies.
