Can you fish catfish in the Yangtze River when the weather is once or twice?

You can't catch catfish in the Yangtze River when the weather is once or twice. Because catfish like high temperature, the water temperature in the Yangtze River is very low when the weather is one to two degrees in winter. When the water temperature is too low, catfish will stop looking for food and be in a semi-hibernation state. So I can't catch it. River catfish is a kind of fish with no scales, sticky and slippery body surface, flat head and wide mouth, and four whiskers on the upper and lower jaws.
