? Snakehead is one of the many freshwater fish living in our country, and it is also a famous freshwater fish. According to the living habits of snakehead fish, their appetite and activity are closely related to the surrounding water temperature. When winter comes, if the water temperature has been reduced to below 10 degrees, the activity of snakehead will be greatly affected. When the temperature drops further, the snakehead will not eat and will enter a state of hibernation, during which they will remain still. Snakeheads generally live in places with more silt at the bottom of rivers, and they may hibernate directly in the silt.
However, this does not mean that all snakeheads will hibernate, whether they will hibernate depends on the specific water temperature. The climate in the north and south of China is different. In some places, the winter is not particularly cold, and the water temperature can still be kept above 10 degrees. At this time, the snakehead may not hibernate, but will continue to feed. In addition, cultured snakehead generally does not hibernate in winter, because breeders usually adjust the water temperature in the water environment for them, so that they can have a strong appetite in winter and continue to grow.
above, whether snakehead hibernates or not is closely related to the water temperature in winter. The same is true of how long the snakehead hibernates, which is closely related to the surrounding water temperature. Generally speaking, the snakehead living in the northern region will have a longer hibernation time because of the early cooling and late warming, while the snakehead living in the southern region will have a longer hibernation time because of the later cooling and the earlier warming. Snakehead needs to wake up from hibernation when the water temperature is suitable, so there will be regional differences.
