Before we start this question, let's understand the question: Why should the stone turtle be heated?
(Circle cards have been added here, please check out the today's headlines client)
There are two purposes for the warming and breeding of stone turtles: one is to reduce wear and tear and ensure the survival rate of turtle seedlings; the other is to accelerate the growth rate of stone turtles, shorten the breeding time, speed up the speed of discharge, and seek to maximize benefits. (Why emphasize this problem, because if there is no problem, there will be no heating, and no one will talk about heating, so it is necessary to understand why it is heated)
Stone money turtle
First of all, the first purpose: to reduce wear and tear and ensure the survival rate of turtle seedlings. Stone money turtle seedlings listed time is the end of June and the beginning of July, until the middle of September, this time is the stone money turtle out of the shell season, and then one or two months after the weather gradually cooler, morning and evening temperature difference gradually increased, which is only grown for a short month or two of turtle seedlings, is more dangerous, the temperature difference is too large, turtle seedlings are prone to cold, if into winter, the temperature is lower, turtle seedlings by their own physical fitness restrictions, may not be able to survive the winter, so, farmers in the first year of the birth of turtle seedlings, usually choose to heat the turtle seedlings for winter, The so-called warming for winter is actually in a specific space, the temperature is adjusted to the best temperature suitable for the survival of stone turtle seedlings, and then normal feeding food, so that it has been in a state of eating, until the end of March and the beginning of April of the following year (taking the climatic conditions in Nanning, Guangxi as an example) before transferring to the outer pond for breeding. After a winter of heating, most of the size of this batch of turtle seedlings can reach between 3-4 two, a small amount can not reach or exceed this weight, in addition, because of the heating guarantee, so the wear and tear of turtle seedlings is very low (warmed overwinter turtle seedlings also die, because some turtles have poor physical fitness, can not live).
Let's talk about the second purpose: to maximize profits. In the past, when the market was good, almost all farmers did a warming box to heat the turtle for the winter, the purpose of heating the winter is to prevent the turtle from entering the hibernating state, so that it has been in a state of eating, because of continuous eating, so, the growth rate of the stone money turtle is very fast, plus the farmers feed a high-protein food combination, which makes the stone money turtle grow faster, so the stone money turtle seedlings can grow to the specifications of the commodity turtle in just three years, so as to put it on the market to sell and earn more profits! (Because the commodity price of the stone money turtle at that time was more than a thousand yuan a pound, the super high profit margin allowed the farmer to be heated at any cost, so that he could take advantage of the strong market demand dividend period and make money fiercely), so it would produce the behavior of heating feeding, otherwise, no one would do this.
After understanding these two purposes, let's talk about the difference between the warmed stone turtle and the stone money turtle that is not warmed (i.e., cold water feeding)?
The first is the difference in size of the head
The same group of turtles, the same location, the warmed breeding of stone money turtles are larger than the cold water raised stone money turtles, cold water raised stone money turtles are smaller than the stone money turtles raised in warming, whether it is turtle seedlings, or the subsequent warming of the turtles. In the two purposes explained in the opening paragraph, it has been said that the warmed turtles are longer than the turtles raised in cold water in terms of feeding time (cold water-fed turtles, which are not warmed in winter, enter the hibernation period, so they are not long or even lose some weight), so the same group of turtles, in the same place, at the same length of time, are fed larger than the turtles raised in cold water under different temperature conditions.
The second is the difference in body characteristics
Warming turtle because of a long time in the state of eating, some farmers feed enough food nutrition, so the turtle grows faster, obesity problem is very common, mainly reflected in the turtle limbs are very fat, limbs contraction, the legs of the flesh are propped out, bulging, like inflatable balloons (of course, cold water turtles will also have this situation, but the proportion of warmed turtles, in addition, the warm turtle's dorsal carapace cold water pattern is not as obvious as the cold water turtle, the cold water turtle pattern is clearer.
Finally, there is the difference in anti-risk ability
Because the warming turtle has been in a heating state in a certain period of time (autumn and winter), the impact on the change of external temperature is very small, so the sensitivity to temperature changes becomes lower, its resistance is relatively reduced, if transferred to outdoor breeding, it is not properly adjusted, it is easy to cause problems because of stress. Relatively speaking, cold-water turtles are more resistant, and due to long-term coexistence with nature, they are more adaptable to natural changes, so the probability of getting sick is lower. However, this does not generally explain who is good and who is not good for the warming turtle and the cold water turtle, and it is necessary to make a comparison under specific conditions to have comparison! (In fact, if the warmed turtle is properly adjusted, it is slowly transferred to the outer pond for breeding, and after a period of time, it is also very good.)
In fact, as far as the current market situation of stone money turtles is concerned, no one is willing to warm up the commercial turtles, because this is a matter of not worth the loss, if you have to heat up the turtles, at most it is to heat the seedlings of the first year, and after that, it is cold water farming. Therefore, the stone money turtle currently circulating on the market, if it is a turtle in the past three years, is basically a cold water turtle, and even if it is calculated in previous years, even if some of it is a warmed turtle, after the cold water breeding in the next few years, it is not much different from the cold water turtle, and the physique is also leveraged. Of course, consumers may be more willing to accept cold-water turtles, but for farmers, they are not much different!
