Eight invasive alien fish species that anglers detest, how many have you seen?

At present, there are many invasive alien fish species in our country. Here are eight invasive alien fish species that anglers detest, see if there is one you are familiar with.

1

Plecostomus (sucker mouth catfish)

This fish (looks disgusting) offers no challenge when caught, and cannot be eaten either. It is a very annoying fish species.

2

Egyptian walking catfish

The Egyptian walking catfish, also known as the Egyptian catfish, is a target fish species introduced from abroad for aquaculture in our country. Compared with the local catfish, it has a larger body, grows faster, reproduces easily, and has strong adaptability; after just one year of rearing it can weigh more than 4 jin. From an angler's point of view, the Egyptian walking catfish is still quite fun to fish for as a target species. But for people who love good food, the reputation of the Egyptian walking catfish is not so good, because it has omnivorous feeding habits and strong adaptability; in some stinking ditches, as long as the environment is slightly suitable, the Egyptian walking catfish can also survive. And compared with the native catfish, even if the Egyptian walking catfish grows in wild waters, its flesh quality is much inferior. 3

Alligator gar

The alligator gar is a large, ferocious fish native to North America, and in our country it mainly exists as an ornamental fish. However, because publicity has not been strong, many people who release animals have released alligator gars into natural waters, bringing enormous damage to our country's freshwater fishery resources. "As long as it is a living thing in the water, it will eat almost anything." Once the alligator gar begins to reproduce in natural waters, with no natural enemies in our country, the alligator gar can easily cause the extinction of native fish species.

Moreover, it is highly aggressive. After being startled, it will attack people, so in recent years incidents of alligator gars injuring people have been increasing. Although its flesh is not poisonous, the meat is coarse and no one would like it either. Even more terrifying is that the eggs it lays are highly toxic, and eating them by mistake can cause death. For anglers, once there is a considerable number of alligator gars in the water body being fished, if no steel wire line is prepared before going fishing, however much conventional line you bring will be ruined.

Green sunfish

Although the green sunfish closely resembles the "crucian carp", unlike the docile crucian carp, it has wide adaptability and omnivorous feeding habits. Whether adult fish or young fish, they all like to devour the eggs and young of other fish, and are highly destructive to the survival and reproduction of fish in mountain streams. Just thinking that there are no longer even topmouth culter or Chinese hooksnout carp in the water makes one quite sad.

5

Serrasalmus sanchezi

Serrasalmus sanchezi, commonly known as the red-gill diamond piranha, is a type of the ornamental fish piranha. It is native to the Amazon River basin in South America and is a ferocious carnivorous fish. Compared with some other fish with good adaptability, this fish has poor cold tolerance; as long as the temperature is below 15 degrees C, it easily dies, so there is no need to worry about it spreading in the water. But for southern anglers who like to go into the water to fish, once this fish appears in the water body being fished, as long as there is a small bleeding cut on the body, it is very easy to be attacked. (Someone thought of going into the water to retrieve a rod, and came ashore covered in blood after being bitten, which is enough to make one's blood run cold.)

Piranha

Just like the fellow above, although its appearance is a little different, its habits are all the same.

7

Tilapia

Grown tilapia are still quite lovely to anglers, but what is annoying is the young tilapia. Finger-sized tilapia eat everything; as long as the hook and bait enter the water, even if corn kernels or raw wheat grains are used as bait, they can swallow them in one bite.

8

Stone moroko

It was originally introduced into our country to control mosquito pests, and now it is distributed in most water bodies. In summer and autumn it is very active, and like the white striped fish, small topmouth culter, and fingernail-sized tilapia, it is a very annoying fish pest. For anglers determined to catch crucian carp, it is a very annoying fish.
