The car is a topic we often talk about, and the core component is the engine, good power is the pursuit of many people, we often say that the V8 engine is the representative of power, it is also the most common engine structure in high-level auto sports.
Today we will talk about the "V8 engine", the reason why it is in double quotation marks, because it is not a real V8 engine, but a fish living in the water, because of the strength is very large, it is described as having a "V8 engine", it is a wheat carp.
<h1 class="pgc-h-arrow-right" data-track="6" > know Mai</h1> Mu
Why is it said that Mai Hao has such a great strength? Let's take a quick look at it first! The full name of the wheat carp is called the Wheat Ray galactic carp, which belongs to the subfamily Cyprinidae of the cyprinid family, native to Bangladesh and India, and is also distributed in other surrounding countries, and is one of the four major farmed fish in India, and its status is equivalent to the four major fish in China.
For friends who have not seen wheat mud carp in the north, you can refer to grass carp, they are very similar in size and shape, long cylindrical, round and straight abdomen, slightly bulging at the dorsal fin, wide caudal fin, deep fork shape, red eyes.
The reason why it can become India's economic fish is that with a fast growth rate, the first year of hatching fry can grow to more than 300 grams in the wild, and in the case of sufficient food sources, it can grow to 700 grams, about one and a half pounds, and the maximum can grow to about 20 pounds.
Tenacious, mostly found in reservoirs, lakes, ponds, rivers, but only in the flow of water can breed, for the benthic fish, temperamental like silver carp good jumping, often close to the shore to feed. The ability to adapt to the environment is very strong, resistant to low oxygen, low temperature, and strong disease resistance.
<h1 class="pgc-h-arrow-right" data-track="36" > invaded China for 30 years and became a hegemon</h1>
In 1982, the Pearl River Fisheries Research Institute introduced wheat carp from Bangladesh, and in the 1990s, as a new economic fish species, it was vigorously promoted in the Liangguang area, and now it has become an important breeding species in the southern region. But in the end, wheat carp is still an invasive species, which is all too familiar to anglers in these areas, and there are many reasons for their flooding.
The main source is the farm, over time, even closed farms will have loopholes, the wheat carp will escape, even if it will be able to trap it for a while and a half, in the rainy year caused by flood disasters, the entire farm may be gone, these mud carp do not want to go. Then there are some "good-hearted" people who like to blindly release their lives, and the mud carp also uses this to escape the day.
The mud carp in the wild, basically belongs to the state of lawlessness, first of all, the wheat carp is not picky eaters, eating miscellaneous, organic plant detritus, plankton, wheat bran peanut bran and other higher plants, small insects water earthworms and some animal larvae are their dishes.
After eating and drinking enough is breeding, in this regard, mud carp is more advanced, an adult mud carp in natural waters, the normal spawning capacity per kilogram is 100,000 to 150,000 pieces, the larger the individual, the higher the amount of eggs, and the life of the mud carp is about 12 years, and the fecundity is more terrifying.
The fatal weakness of all kinds of fish living in the south is the fear of low temperatures, such as tilapia, but mud carp is unique in terms of low temperature tolerance, and can operate normally at 7 ° C, while the native mud carp has long been dead and warped. Studies have shown that the critical lethal low temperature of wheat carp is 3 ° C, and it can even adapt to natural waters with higher latitudes such as the Yangtze River.
Its strong survivability allows it to easily defeat native southern fish, and can even replace other fish and grow the number of races under the super competitiveness. And now Mai Mu may have defeated the invading king's tilapia and become the "first brother" of the Pearl River Basin, why is this?
Researchers at Shanghai Ocean University conducted a random sample survey of fingerlings in the Pearl River Basin in 2019, and of the 5867 fish samples, invasive alien species accounted for 15.8% of the total catch, for a total of 927. Among them, there are 407 wheat carp, 360 Nile tilapia, and 118 tilapia, purely from a certain fish species, wheat carp is obviously "dominant", is an absolute advantage invasion fish species.
The situation is roughly the case from the local fishing population, followed by the Rusta wild carp (Thai carp), the leather-bearded catfish, the mosquito-eating fish, etc., while the local four large fish have long been excluded from the top ten, in other waters, wheat carp can also enter the top three, in some waters even only wheat carp this invasive fish species, the overall degree of difficulty and distribution exceeds the tilapia.
As for tilapia, everyone is familiar with it, as early as the 60s of the last century, it settled in China, and in the 1980s, it was developed that is more suitable for the survival of tilapia in Guangdong, and since then, tilapia has accounted for about 23% of the total number of fish in the Pearl River. But this time the overlord transposed, and Mai Hao came to the top, which surprised everyone.
<h1 class="pgc-h-arrow-right" data-track="37" > connivance from foodies and anglers</h1>
It is said that the species that can flood in Our country, that is quite powerful, the saddest pass is the foodie, such as crayfish, the original population is very large, many rural post-80s have a deep feeling about this, but with the rise of foodies, now can only rely on breeding to continue life, then wheat carp is escaped from the foodie's "pursuit and interception"?
Although wheat carp was originally a farmed economic fish species, most of the individuals on the market are between 400 and 700 grams, to say that the taste is OK, but the size of the wheat carp, the meat quality is relatively woody, and the local mud carp compared to the gap is too large, can only be made into fish balls, or dried into salted fish. Many individuals of wild wheat carp are beyond the scope of being able to eat, can not raise the interest of foodies, and can naturally "escape from the tiger's mouth".
And for anglers, the wheat carp is definitely a darling, because its power in the water is very large, just like the installation of the "V8 engine"! It feels very good to fish, but it is a headache after landing, and the impression of "not delicious" makes many people choose to throw it back into the river. Coupled with the super ability to survive and reproduce, flooding is inevitable.
<h1 class="pgc-h-arrow-right" data-track="38" > grass carp, soil carp, Thai carp, wheat carp silly distinction is not clear</h1>
Grass carp vs wheat carp: grass carp belongs to one of the four major fish, is also one of the most photographed freshwater fish, different places call it differently, but its appearance and wheat carp are strikingly similar, ordinary people may not be able to distinguish between true and false.
The two fish can be distinguished from the details, the dorsal fin of the wheat carp is slightly higher than that of the grass carp, the fin is slightly diamond-shaped, the back is slightly black, the lateral line is slightly spotted, the eyes are red, and the growth limit is about 20 pounds. The grass carp's fins are round and neat, the back is grass blue, the lateral line is obviously neat, and the eyes are black and white, which can grow to about 50 pounds.
Mud carp, wheat carp, Thai carp family: these mud carp belong to the carp family, have a similar feeding style, belong to tropical subtropical fish, similar distribution range, spawning requirements are relatively high.
The difference is that the mud carp is a native fish in China, and there are several blue fish scales behind the gill cover, and the individual is about 1 pound. The scientific name of the Thai carp is Rusta wild carp, which was introduced from Thailand in 1978 in China, and its body is like a carp, with the largest individual. It is shaped like a grass carp, with a pair of small whiskers at the corner of the mouth, pale yellow fins, and silver scales.
From the perspective of a foodie, the best taste of the mud carp is undoubtedly the most popular, but for the anglers, the thai carp has become the most popular. However, it cannot stand the largest number of wheat carp and the widest distribution range, coupled with the power as strong as the "V8 engine", it is unreasonable and unreasonable, and the anglers are cut countless lines, which has become an eternal "nightmare" in the hearts of anglers.
