Whether map turtles need to be warmed in winter depends on whether breeders want them to hibernate. If breeders don't want them to hibernate, they need to be warmed. Because the temperature is low in winter, they have higher requirements for water temperature. If they are not heated, their growth will be affected and they may freeze to death. Therefore, breeders don't let them hibernate, so they need to use heating rods to keep the water temperature between 26-28 ℃.

If breeders want them to hibernate, they can not heat them. When the temperature is lower than 10 ℃, they will go into hibernation, and when the temperature is lower than 5 ℃, they will go into deep hibernation. Although they have low temperature requirements after hibernation, breeders cannot keep them outdoors. After the map turtles go into hibernation, the breeder needs to transfer them indoors and ensure that the temperature is above 0 ℃.

Map turtles also need to be warmed at ordinary times, because their origin is tropical, so they have higher requirements for water temperature. Their most suitable water temperature is between 26-28 ℃, which is generally unable to reach their required temperature except summer. If the water temperature is too low, they will lose appetite and reduce their activity. Long-term low temperature will also affect their growth and development, so heating is also needed at ordinary times.
