Which fish have strong cold tolerance?

Cold comes and summer goes, autumn harvest and winter storage. Different regions and seasonal changes lead to different habits of various fish. Some fish are cold and afraid of heat, some fish are cold and afraid of cold, and some fish have strong adaptability to cold and heat. For us fishermen, we must master these objective laws and catch different fish in different regions and seasons. So, which fish have strong cold tolerance? Which fish are the most heat-tolerant? Next, we classify fish according to temperature, and talk about tropical fish, temperate fish and cold water fish respectively.

First, tropical fish. Tropical fish mainly live in tropical and subtropical regions, preferring water temperature above 25℃. When the water temperature is lower than 15℃, they will be on the verge of death. Tropical fish in China are mainly distributed in the provinces south of the Yangtze River, and tilapia is a tropical fish that fishermen often catch.

Second, temperate fish. Temperate fish refers to wide-temperature fish, which has strong adaptability to temperature. The highest water temperature is above 30℃, and the lowest water temperature is 0℃. The most common freshwater fish we see, such as crucian carp, carp, herring, grass carp and silver carp, belong to temperate fish. Crucian carp, in particular, can catch fish regardless of the temperature.

Third, cold water fish. Cold-water fish refers to fish that can withstand low temperature and high temperature. They are active at low water temperature, and will die when the water temperature exceeds 20℃. The cold-water fish in China are mainly distributed in some provinces in the north, especially in the northeast. Such as willow root fish, pike, rainbow trout and so on. In recent years, willow root fish has gradually become the mainstream of winter fishing, and it is often released in the black pit fishing ground in the north.

Fourth, mainstream fish species. Crucian carp and carp are freshwater fish with the highest fishing frequency in China, and they can fish all year round. In addition to these two kinds of fish, the main fish caught in the south are tilapia, herring, grass carp, silver carp and pouting fish. The main fish caught in the north are herring, grass carp, silver carp and willow root fish. No matter what fish you catch, the taste of bait is very important. Different fish like different smells and use different bait formulas.
