Under normal circumstances, algae will not grow on the tortoise shell, so in order to make algae attach to the tortoise shell, we must artificially create some conditions: crush the tortoise shell with a file and make it rough, coat it with ginger to make the rough tortoise shell produce mucus, and then dry it without touching water to form a "culture medium" suitable for algae attachment and growth.
Because turtles can run around, their activities must be restricted during vaccination. Their method is to put them in a small jar.
Turtle's excrement will pollute the water body, but changing water means that the algae spores collected hard will also be dumped, so their practice is not to feed turtles a few days in advance, even until the end of inoculation. Although turtles can eat nothing for a long time, it's feeding season around 25℃, and it's really hard to be hungry at this time.
Imagine: turtle dealers picked hundreds of turtles, smashed them, smeared them with ginger, and then put them in hundreds of small pots and soaked them with high concentration of algae. They won't eat until they grow little green hairs. Really cruel!
Second, the feeding process is cruel: algae corrode turtles and are prone to onychomycosis, which is difficult to find in the early stage.
After being cultivated into a green turtle, the life span of the turtle will also be affected. The root cause is that the filed tortoise shell and the green hair covering the whole body cover up some lesions.
Friends who have raised turtles know that the most common disease of turtles is "rotten skin and nails". As the name implies, the most obvious feature of this disease is the decay of skin and tortoise shell, and the cause is mostly related to water quality.
In the initial stage, spots will appear on the diseased parts one by one, which is easy to find on ordinary turtles. Most of the green turtle's body is covered with this green clothes. Once the turtle has a common "rotten nail", it has passed the best treatment period, especially the turtle shell. The owner often finds the abnormality when the turtle shell festers, the green hair falls off or even does not eat.
