The turtles in Nanhu Lake in Wuhan are in droves. What's going on here?

Someone released these turtles in Nanhu Lake, so people caught them while fishing. Because these turtles are all ink turtles, they are all cultured indoors, and it is difficult to adapt to the cold lake after relaxing, so they naturally run up. What happened at that time was actually like this. South Lake is located in Wuhan, with a wide water source. Many people will fish in the lake, but generally on the shore, its water is shallow and there are aquatic plants, so it is difficult for people to catch fish nearby.

If it is a short fishing rod, basically there will be no good harvest. But what I didn't expect was that people put on long sleeves because of the cold weather at that time, so many people immediately took fishing rods in the morning to see if they could catch herring and grass carp.

But unexpectedly, an old man caught a turtle in the lake. This makes the old man very happy. He often fishes by the lake. He once caught a turtle in the lake. But I didn't expect to catch a turtle this time. After that, he put the fishing rod into the lake and continued fishing.

After the first turtle appeared, the second, third and more turtles appeared, which surprised the old man very much. It is believed that this turtle is an alien creature, so it will cause serious water pollution. Many people say that if so many turtles are in South Lake, aren't all the fish in it eaten up?

In fact, these turtles are all ink turtles, which are transformed from grass turtles. It's not a foreign thing, it's a local turtle. Many people have said, since it is a local turtle, why is it so rampant in Nanhu? In fact, after people learned that these turtles were released after buying and selling, they just didn't know that this turtle was raised in an indoor greenhouse. It is difficult to adapt to the temperature of the lake after release, so naturally they all ran up.
