You can imagine that fish can actually climb ashore and migrate in large armies like land animals, and this topic can definitely subvert the brains of most people!
In fact, for fish, for ordinary people, there is still too little recognition. In our daily life, the common freshwater fish is nothing more than more than ten varieties of grass carp, carp, carp, bream and so on.
But no matter what kind of fish it is, what we know is that the fish will die without the water. However, there is a kind of fish that does not die without leaving the water, but can also climb over mountains and mountains, and migrate on land. This ability also almost created a precedent for the land survival of fish!
However, what surprised countless people was that even with such a strong ability to survive, this fish has become a "shameful" existence for countless fish, and the fish will actually be "drowned" by the water. What kind of fish is this, what kind of existence!
快来认识它，过山鲫——攀鲈！
On the mainland, there are 1050 species of freshwater fish, with a total of 18 orders, 52 families and 294 genera. Among them, there are 967 species of pure freshwater fish, 15 species of migratory fish in haihe rivers, and 68 species of estuarine fish. And what we want to know today is a kind of fish of the order Perciforme among freshwater fish!
Catalpa perch: scientific name climbing perch, perch, climbing perch! The main reason why it is called a crucian carp is that it looks like a crucian carp; there are also fine spines on its gill cover, which can use the thorns on it to climb and move freely by swinging its tail!
Climbing perch, flat and long, with teeth up and down the mouth, a flat and short tail, covered with small black dots, prefer to inhabit the slow flow of the river ditch and pond, the juvenile fish mainly feed on miniature aquatic animals, such as small fish and shrimp, etc., for omnivorous fish.
The first thing that was discovered and made known to it was the Danish scientist Dardorff, who, during an expedition to Tranquiba in 1791, accidentally found the fish sucking juice in the fruit of a tree. After he learned about the local residents, and finally after his return, he reported what he saw in detail, so that human beings also knew about this magical fish, and after the report came out, it caused a sensation in western society at that time!
The report describes it as follows: A climbing perch is climbing up in a tree gap not far from the pond, it uses the open gill cover, it uses the thorns on the gill cover to support itself in the gap, and then uses the swing of its tail and the thorns on the fin to propel itself forward, relying on this way to climb to the tree and enjoy the fruit juice of the tree. ”
The origin of the climbing perch is many, involving a total of 17 countries of all sizes. The mainland is mainly distributed in Hong Kong, Fujian, Guangdong, Guangxi, Taiwan, Hainan and Yunnan rivers, wetlands, rice fields.
攀鲈能攀山越岭，却因“淹死”被鱼类所不耻！
For climbing perch, it has the ability to be envied by countless fish and land. It can survive for 6 to 8 days without water, and can bounce around the shore freely.
And the reason why it has such a powerful ability is because it has a function that almost all fish do not have, the gill organ, which is independent, and its greatest role is to assist breathing.
It is precisely because of this function that it can ensure that it can survive without water, and the gill carrier can let it absorb oxygen through the air on the shore. If it is in the water, it can also exchange it for oxygen in the water through another organ, the gills. Therefore, it is also because of these two functions, so that countless fish envy.
However, at the same time as envy, the climbing perch also causes it to become a "scum" in the fish for another reason, and it will actually be drowned by the water when it is born as a fish.
In fact, heaven is fair, which is not a bad thing for climbing perch. To paraphrase: God has opened a window for you, then a door will be closed for you!
Climbing perch is the best description, the main disadvantage of its drowning is that it does not have a swim bladder, that is, the gills are a scaled-down version. And the amount of oxygen in the water is not enough to support it for a long time. Therefore, it needs to swim constantly in the water, and once the oxygen is insufficient, it must expose the head to the surface of the water to breathe oxygen in the air.
If it moves a little slower, it will sink to the bottom of the water due to lack of oxygen and drown alive by the water.
It is for this reason that it has also become the laughing stock of the fish world, the scum of the fish.
从被视为“害虫”，到如今的香饽饽！
The existence of the climbing perch has long been hated by countless people. Its existence, like the Tilapia in the two guangdong regions today, is simply a scourge.
However, unlike tilapia, which is a pure native species, tilapia is an invasive alien species. In fact, many of the habits of climbing perch are somewhat similar to those of Tilapia, with super reproductive ability and strong sociality.
The climbing perch matures quickly, from hatching to maturity, it only takes a year and a half, and an adult climbing perch can lay more than 2,000 eggs at a time. Moreover, the adaptability of the climbing perch is also outstanding.
Unlike other freshwater fish, once some waters appear to be polluted and die, they can adapt to this polluted water quality very quickly and survive. The reason why climbing perch will be disliked by many people is more reflected in farmers.
Because of the land viability of climbing perch, once the breeding pond allows it to successfully reproduce, they will jump out of the fish pond, in the process of crossing other fish ponds, it is likely to bring different germs, resulting in entering other fish ponds, bringing germs, and letting other fish species infect and get sick, resulting in a large area of fish ponds.
Another annoying thing is that the climbing perch is also a ferocious fish and is extremely aggressive. Therefore, once food is scarce, they will use the seedlings and eggs of other fish as a food source. This also understands that it destroys the reproduction of other fish species and causes damage to the entire food chain!
There are good and bad, but today's climbing perch has become a fragrant feast for most farmers because of its meat quality. Like other perchs, climbing perch have a more obvious feature. That is, the meat is delicious and has fewer thorns. Although the individual is relatively small, it has reached the level of edible. Therefore, today's climbing perch has also become a hot product in the market, and the price has also risen.
总结
Climbing perch, the wonder of fish, but at least it brings many different visions to many people. With the acceptance of the market, what was supposed to have the opportunity to go to the flood is now becoming more and more rare in the wild because it is edible. After all, under the mouth of a foodie, no matter how powerful it is, it is only in vain.
The peculiarity of living out height and speed is dead, this is the magical fish of climbing perch, bouncing and jumping in line for "parkour". Do you recognize it?
