الوصف: This study explored the thermal tolerance and routine metabolic rate of ten small indigenous fish species from Northeast India: Amblypharyngodon mola, Esomus danrica, Puntius sophore, Gudusia chapra, Heteropneustes fossilis, Botia dario, Lepidocephalichthys guntea, Mystus cavasius, Aplocheilus panchax, and Glossogobius giuris. Fish were acclimated to 20°C, 25°C, and 30°C for two weeks prior to experiments and assessed for critical thermal maxima (CTmax), critical thermal minima (CTmin), lethal thermal maxima (LTmax), oxygen consumption rates, and respiratory quotients using standardized methods. The results revealed significant interspecific variations: CTmax ranged from 36.4°C to 41.7°C, CTmin from 8.7°C to 15.2°C, and LTmax from 41.5°C to 44.9°C. Oxygen consumption rates varied between 0.26 and 1.07 mg O₂/g/h, with respiratory quotients ranging from 0.76 to 1.01. Heteropneustes fossilis (CTmax: 41.7°C at 30°C acclimation) exhibited the highest thermal tolerance, while Amblypharyngodon mola had the lowest (CTmax: 38.2°C at 30°C acclimation). Differences in thermal tolerance between species were statistically significant (p
