Black perch, most places call it largemouth bass, native to Canada and the United States, Taiwan was introduced in the 1970s, Shenzhen, Huiyang, Foshan and other places also introduced largemouth bass fry in 1983, and in 1985 successively artificial breeding success, black perch is mainly cultured by artificial, extremely rare in natural waters.
Recently, Mr. Zhang (pseudonym), an angler from Jurong, Jiangsu Province, was fishing in a local stream, but accidentally found a large number of black perch, and caught nearly 30 in just half an hour...

In the humble creek, black perch flocks
"On the same day, I was because there was something going on at home, and then I went back to my hometown, and after eating at home, I went around the village with a Luya rod, thinking of throwing a few rods to try it, and I didn't think about throwing a few rods to catch the black perch, feeling that they were very hungry and grabbing food very badly." Mr. Zhang (pseudonym), an angler from Jurong, Jiangsu Province, said slowly.
"This small river in the village, strictly speaking, can only be regarded as a small stream, there is a reservoir with a medium area upstream, so there will be water here last year, and the last time I came back, I caught some small cockfish, but I didn't expect that this time there would be black perch biting hooks." Mr. Zhang added with some doubt.
Fished nearly 30 in half an hour, worried that it would "flood"
Mr. Zhang, an angler, also said that he had only caught this black perch in the "black pit" before, and he was still the first time to catch this fish in natural waters, and this time he fished for half an hour here, and he caught nearly 30 black sea bass.
From the pictures provided by the angler Mr. Zhang, we can find that these black perch are large and small, the large one is likely to have reached sexual maturity in adulthood, and the small one is at the level of fry, and it is this mix and match combination that makes Mr. Zhang feel worried.
If these black perch have reached a level where they can reproduce normally, then without human intervention, their populations will expand "unlimited", so Mr. Zhang, an angler, expressed concern that these black perch would "flood", and Mr. Zhang also said that this kind of perch that suddenly appeared in the wild river, small ones brought home to the fish pond, can the large ones be eaten?
Black perch has a natural advantage
It is understood that as an alien species of black perch, their adaptability and reproductive ability are very good, its meat is delicious and nutritious, the edible taste is also very good, so the domestic price is also higher than the crucian carp and other common freshwater fish, is a more popular freshwater fish in the market.
After the introduction of black perch into the country for artificial culture, affected by some external factors, such as heavy rainfall, fish pond collapse, cage damage, etc., so that some artificially farmed black perch escaped to natural waters, because there is no balance of natural enemies, coupled with their strong adaptability, they swallow other freshwater fish, causing more serious damage to our water ecology.

Will black perch with such a huge survival advantage "flood" in our rivers?
After the cage culture was no longer allowed in the rivers a few years ago, the farmers in the Wujiang River accidentally let some black perch escape to the Wujiang River in the process of dismantling the cages, originally thought that these fish would "flood", who knew that a large number of anglers heard the news, under the "siege" of many anglers, a large number of black perch were caught ashore, and then never heard of the flooding of black sea bass in the Wujiang River.
It turns out that the black perch is extremely gluttonous, and will also attack violently when facing the Lua fake bait, although they have no natural enemies in fresh water, but when facing humans, it still looks a little small, who makes them delicious and nutritious.
However, some netizens said: "Now that the Yangtze River Basin is carrying out a ten-year fish ban plan, I don't know if it will give these black sea bass a chance to breathe." ”
Friends, have you ever seen or fished this kind of black perch, do you think that in the case of no one fishing during the fishing ban period, these black sea bass will usher in the opportunity of "flooding"?
