Yangtze River Jun: Generally speaking, wild fish are timid and afraid of people, especially large fish will not easily surface, but any movement will burrow into the depths of the water.
However, in the urban river channel of Guangzhou, Guangdong Province, someone recently filmed a bizarre scene...
—— A big fish swims upstream, and after encountering passers-by, it not only does not escape, but "very stubbornly" swims up the river, and is finally fished away by passers-by...
01Why is this fish so persistent?
According to The Yangtze River Jun, because of the recent rainfall in the Guangzhou area, the urban river in the Nansha District is also relatively turbulent.
I don't know if it was because of the river's rising water, this one or twenty pounds of large fish (visually it is the Egyptian pond catfish) swimming upstream against the current, but when passing a small dam with rapid water flow, the big Egyptian catfish was trapped...
"At that time, it was desperate to swim upstream, but the water flowed too fast to go up, and as a result, someone took the net to fish."
Mr. Liang, a Guangzhou citizen who filmed this scene, said that such a large fish in the river against the current, the picture is indeed relatively rare, so it also attracted the attention of many passers-by, among them, some people "saw the hunter's heart", took the net to catch fish.
02 Passers-by tried several times to finally capture it
Because the shore was far from the water, the man who fished for the fish took a large net to catch the fish, and even tried several times without picking it up.
But what is even more surprising is that this big fish did not run away after finding someone fishing, or very "persistently" rushed upstream against the current...
---------------------------------------
And after the passerby tried many times with the net, he finally caught this big fish - sure enough, it was a more common "big Egyptian catfish" in the Guangzhou river, that is, the Egyptian pond catfish, which is a leather-bearded catfish under the catfish order, which belongs to invasive alien species.
The shooting distance is relatively long, but it can also be seen that this fish is not small
From the picture taken by this Guangzhou netizen, this big Egyptian catfish is not small, it should have more than ten pounds.
Of course, such a large Egyptian catfish is not uncommon in the river channels of Guangzhou, but it is surprising why this large Egyptian catfish does not escape under the catch of passers-by, but swims upstream?
03 Netizen: This fish should not be fished
In this regard, many netizens believe that the reason why this big Egyptian catfish is so "persistent" is to go upstream to lay eggs! Friends who like to fish should know that many wild fish do have the habit of spawning retroactively, which is to facilitate the hatching of fish eggs and the development of fry.
Some netizens commented
Therefore, this Egyptian catfish's move of ignoring passers-by and desperately impacting upstream has been interpreted by many netizens as "desperate for future generations"; "This is a fish with a sense of mission".
Moreover, many people believe that this kind of "fish with a sense of mission should not be fished", and this passerby is "too unrefined"...
04 Is this really a "fish with a mission"?
In the view of Yangtze River Jun, the breeding window of the Egyptian catfish is relatively long, and this "persistent Egyptian catfish" does have the possibility of laying eggs against the current.
The breeding season for Egyptian pond mackerel is from April to October – pictured
However, the Egyptian catfish is an invasive species with great ecological harm in China, and it is not a "good stubble" for the native fish and shrimp aquarium - if this is an Egyptian catfish to spawn, it is even more harmful.
It should be said that there is nothing wrong with picking it up and "strangling thousands of small Egyptian catfish fry in the cradle", not to mention that the fish catcher can also harvest a good meal when he fishes it away...
Of course, the above is the Yangtze River Jun's view from the perspective of river ecology, old drivers, do you think this fish should be fished?
