Yangtze River Jun: Military fish with magnificent appearance and fierce nature, known by many fishing enthusiasts as the "king of fresh water", as soon as it appears, it will often arouse the attention of many anglers.
In the Lancang River in Yunnan, there is a strange fish with "strong body and fierce strength", which some people call the so-called "king of fresh water" - military fish.
Military fish?
Are these big fish with thick scales and a "mighty" appearance military fish?
<h1 class="pgc-h-decimal" data-index="01" data-track="59" > which is a rarer "Chinese knot fish" than military fish</h1>
In fact, judging from the appearance of these big fish, these fish are not military fish, but the rarer and even somewhat mysterious "Chinese knot fish".
This is not a military fish, but a knotted fish
Knotted fish was once widely distributed in China's Yunnan region, and the "mighty" and magnificent appearance made many people unforgettable, and even many fishing enthusiasts every year rushed to the China-Myanmar border to pursue this strange fish.
- But most people will be disappointed.....
<h1 class="pgc-h-decimal" data-index="02" data-track="37" > legend requires "worshipper" to catch</h1> it
Although the fish has a large amount of food and fierce feeding, it is easy to be hooked, but it is very difficult to catch - Yangtze River Jun listened to some Yunnan fishing friends say that even in its place of origin, many people are difficult to get a few a year, and the legend requires "worship" to catch!
It is said that this is because the knotted fish often inhabit the difficult and deep sections of the river, and the current is often turbulent, and it is very difficult for the average person to catch them, not to mention to find a hiding place.
Therefore, in order to experience the exciting experience of fishing for such a fierce big fish, it is necessary to have some "teachers" to teach and bring - especially considering the high economic value of the fish, if you are not sincere in worshiping the teacher, it is difficult for anyone to be willing to teach.....
The mystery and curiosity of the knotted fish can be seen from this...
<h1 class="pgc-h-decimal" data-index="03" data-track="40" > fish is probably one of the most mysterious species</h1>
In the impression of Yangtze River Jun, although the fish is very well-known, few people say anything about the biological characteristics, classification, etc. of the fish.
Even what its scientific name is, even the old fishermen along the Lancang River, are often inconsistent and difficult to determine.

Yangtze River Jun: The research literature on knotted fish is far less than the well-known freshwater fish such as carp, grass carp, mandarin fish, military fish, etc., and even in the eyes of Yangtze River Jun, it can be called one of the "most mysterious" native large-sized fish in China.
What kind of fish is the Chinese knot fish? Is this the scientific name of the knotted fish? What is their relationship with military fish?
<h1 class="pgc-h-decimal" data-index="04" data-track="42" > decrypt Chinese knots</h1>
Changjiang Jun: There is indeed less research literature on Chinese knot fish, and after consulting many aquatic literatures, ChangJiang Jun only found a relatively comprehensive classification and analysis of knot fish literature - and it was still formed in 1985, which shows that there is very little research on knot fish.
According to the understanding of Yangtze River Jun, the knotted fish is actually a general term for the next type of fish species in the cyprinid family and the subfamily of catfish - this type of fish is called the knotted fish genus, which is evolved from the four-whiskered catfish and the round-lipped fish.
At present, there are still ancient fish species such as four-whiskered catfish in Yunnan
In addition, there are a total of 3 subgenera and 9 species of fish (including subspecies, of which 8 species are distributed in Yunnan), including semi-spiny knotfish, yellowfin knot fish, large scale knot fish, Chinese knot fish, Yunnan flap knot fish, Hainan flap knot fish, etc.
Like the "fierce big fish" caught by the Yunnan anglers in the Lancang River above, it should belong to the large scaled knot fish, and the "red wing" called by the locals may be a yellowfin knot fish.
However, the body size of all kinds of knotted fish is relatively similar, so it is difficult to distinguish only from the appearance, and it is no wonder that in the folk, it is often collectively referred to as "Chinese knotted fish"...
Yangtze River Jun's Note: As a reference comparison, the military fish that anglers worship as the "king of fresh water" are species of the genus Barbed Catfish under the cyprinid and catfish subfamily, and the two are closely related, and it is no wonder that many anglers often misidentify them.
In addition, although the knot fish is very "mighty" at first glance, and the older generation of fishermen and anglers also call it "very fierce", the knot fish has evolved a different path from the military fish - its habits are closer to carp.
The "ancient ancestor" of the knot fish is the four-whiskered catfish, which is an omnivorous fish species, but the knot fish has slowly become a benthic fish in evolution, mainly feeding on various higher plants and algae, followed by various arthropods and rotifers, protozoa, which can also prey on other fish and shrimp aquariums, but in the study, it is rare to find the swallowed fish and shrimp aquarium from the intestines of the knotted fish...
(In other words, knotted fish are actually "vegetarian" fish species— relatively speaking.) ）
<h1 class="pgc-h-decimal" data-index="05" data-track="46" > the "death of the fish" under overfishing</h1>
As a magnificent and ancient fish, the knot fish was originally distributed throughout the middle and lower reaches of the Lancang River, and was distributed in Fuxian Lake and Dianchi Lake in Yunnan.
However, in recent years, due to the ecological environment and artificial cool fishing, the number of wild agglomerates in China has been very small - but the downstream Mekong River Basin is more common.
The height of the Lancang River has a large drop, so there are many hydropower stations - data map
In the environment of dams, indiscriminate fishing is becoming the "last straw" for the depletion of the fish population - the sexual maturity age of the fish is generally around 4 years old, and in recent years, the vast majority of the fish caught by fishermen are under 2 years old.
That is to say, many knotted fish "do not live to adulthood", and their populations are naturally unsustainable, and even some of the knotted fish species have quietly disappeared.......
The smaller the fish are caught
In fact, many other rare fish have encountered similar dilemmas of "not living to adulthood", such as the green bamboo fish (barbed catfish), the military fish (light barbed catfish), the Qingbo fish (Chinese barbed catfish) of the "three brothers" of the barbed catfish genus.
——After understanding the survival dilemma of these rare fish, everyone will know why the Yangtze River Basin should be completely and completely banned from fishing.
Because if we follow the current ecological background and fishing situation, even if the seasonal fishing ban (breeding period) is strictly implemented every year, it will not help in the end.
I believe that if the ecological environment of the Lancang River Basin can continue to improve, these ancient and magical big fish will flourish again...
