With the continuous development of human society, it will cause certain damage to the ecological environment in the process of social development. Especially in coastal areas, due to the rapid industrial development, the environmental pollution is also very high, which has also caused great damage to the local ecosystem, and many species are even on the verge of extinction. Because of this, with the rapid extinction of species, many countries have realized the seriousness of the problem and started to strengthen environmental protection.

Although there is no effective way to control the extinction of species, the extinction rate of species has slowed down compared with the beginning. Under the deliberate protection of human beings, the number of species has been effectively controlled, and with the development in recent years, its number is slowly increasing. There used to be a kind of fish in Guangdong, which was originally considered as an exotic species. Later, after a detailed investigation by experts. This kind of fish is not only not banned, but also very welcome to enter. What kind of fish is this?

Alien species found in the river

This happened in a river between Guangdong and Foshan. At first, fishermen found this kind of fish that they had never seen before at work. This kind of fish looks like both a fish and a snake, so local fishermen call it snakehead. Because it looks particularly like snakehead, many fishermen regard it as a species of snakehead and don't think much about it.

But with the passage of time, these fishermen gradually found that this kind of fish seems to be different from snakehead, and it seems that this kind of fish is not big and is extremely opposite to snakehead. Because snakehead is more aggressive, but this kind of fish is gentle and not aggressive. So at that time, many fishermen thought it was an exotic species, and some experienced fishermen naturally knew the harm of exotic species.

Experts welcome this species.

So I quickly reflected this situation to the relevant departments. Later, after learning about the invasion of alien species, we also attached great importance to this matter. Later, after on-the-spot investigation and a lot of research, the experts were not nervous, but very happy, and told local fishermen that this kind of fish is not an exotic species, so don't worry. Even experts welcomed this kind of fish, which made the fishermen nearby even more puzzled, because many fishermen here lived by water, but they had never seen this kind of fish in the water.

Experts say this kind of fish is not an alien species, so what kind of fish is it? Later, experts introduced the fish to the villagers in detail. This kind of fish is called seven-star fish. At first, the fishermen were right. Their appearance is very similar to that of snakehead. However, it is not a snakehead. They are native fishes of the Pearl River. As for why many people haven't seen this fish, it's because it has long since disappeared. Because this kind of fish has very high requirements for water quality.

The effort paid off.

However, while human beings are vigorously developing the economy, they have caused great pollution to rivers, resulting in the gradual disappearance of this fish because it can not adapt to life in the water. This is why many people have never seen or even heard of this kind of fish, so when the seven-star fish reappeared in the river, many fishermen thought it was an exotic species.

However, the reappearance of the seven-star fish has made everyone have a better understanding. In recent years, the country has achieved very beneficial results in environmental protection. Their reappearance also shows that the water quality here has reached their living conditions. At the same time, it also shows that in recent years, people are committed to protecting the environment and have achieved remarkable results. This is a good phenomenon, which proves that our efforts have not been in vain and everything is developing in a good direction.
