Those fishermen who live by the river will spread such a saying, no matter how big the pig grows, it will be more than 300 catties, and the fish is too big, so it is estimated that there is no way to call it. From this sentence, we can know that if the fish in the river keep growing, that head will reach an unbelievable level. For example, a fishing friend in Guangxi recently, he posted a rhubarb tip of more than 100 catties on social **, the fish was quite shocking, and it received many clicks and discussions from netizens.
In Guangxi, Huangjian is commonly known, and its scientific name is actually called squid, which is the well-known water tiger. The water tiger caught by the angler can be said to be the king of fish, after he pulled the fish up, passers-by nearby also came to take pictures and watch. But what he didn't expect was that after people on the Internet saw the rhubarb tip sun, they all felt incredible, and some netizens even said that this fish was estimated to be bought, and there have been no big fish in the Xijiang River for many years, and if it is really wild, it is estimated that it has lived for decades.
In fact, there is a reason for the disbelief of netizens, the body size of this rhubarb tip is already as thick as that of an adult, and if you look at it from the **, the visual impact is still very strong, and it does not look like a wild one. In the past few years, the fish resources in China's natural waters are facing depletion, and there are fewer and fewer large wild fish, so when netizens saw this fish, they thought it was bought from the farm.
But in fact, since the ban was put into effect, there are indeed such large wild squid in the Yangtze River, and the number continues to increase, and there will definitely be more big fish in the future. As can be seen from the situation in the past two years, there has been a marked increase in the number of people who have fished dozens or even hundreds of catties of large squid from the Xijiang River. Now that the concept of protecting the ecology of the river is in place, the behavior of medicinal fish and electric fish in the Xijiang River basin has been greatly reduced, and the situation of sewage discharge has also been greatly improved.
The ecology of the Xijiang River has improved, and the number of large carnivorous fish such as squid has naturally increased. On the other hand, the increase in alien species is also helping the development of the squid, the squid eats more, if there are more fish in the waters, the squid will naturally grow bigger, especially in the waters where alien species have invaded, the probability of large squid appearing in it will be higher.
In some ways, the increase in the number of native squid can control the proliferation of foreign species, however, there are still netizens who are worried about the proliferation of native squid, this large carnivorous fish grows very fast, and eats a lot, a squid will eat a lot of fish in the river in a year, if the number of squid is overflowing, will it be a threat to the river ecology?
In fact, no matter what kind of fish it is, as long as its number exceeds a limit, it is a disaster for the ecosystem, even if it is a vegetarian fish such as crucian carp, grass carp, and carp, and even more so for large carnivorous fish such as squid. However, judging from the current ecological situation of the Xijiang River or the entire Pearl River, it is still far from the number of them becoming a disaster, and the probability of their occurrence in the future will be very low.
It is still difficult for the squid to flood, because the squid itself is not a fish with strong reproductive ability, and the growth of their population will be affected by the number of other fish in the waters.
The predatory of the squid is very strong, as long as it is hooked, it will not run, it is an easy fish to catch, and there are so many anglers in Guangdong and Guangxi, it is more difficult for those squid living in the Pearl River system to flood. As a carnivorous fish, they can be said to be the fish that can best reflect the ecological situation of the river.
