In recent years, due to the deterioration of resources, not only are there fewer and fewer fish, but the individual fish are also getting smaller and smaller, and if you want to catch large individual fish, the luck component is too large, even if you keep big fish, you can't catch it.
Even the most common crucian carp, it is difficult to catch more than half a pound of individuals, after catching a large crucian carp, some anglers said: "This is all engineering crucian carp, where is the earth crucian carp so big?" ", so are the individuals of crucian carp small? It's just a rumor! Because some species of crucian carp are themselves very large, even growing to several kilograms, some varieties of crucian carp have once been a royal tribute.
Crucian carp caught are generally smaller individuals
<h1 class="pgc-h-arrow-right" > what is the definition of "earth crucian carp, engineer crucian carp"? </h1>
Crucian carp and engineered crucian carp are both crucian carp, the former is not artificially selected, artificially bred, native crucian carp; the latter in order to make them grow faster, more economical, artificial control of their species, through artificial intervention to breed the crucian carp, called "engineered crucian carp".
Crucian carp and crucian carp grow very slowly in our minds, and it is difficult to appear huge individuals. More than half a kilogram of earth crucian carp is relatively rare, and even some anglers say that "it takes at least 5 years for the earth crucian carp to grow to 1 kilogram", although this statement is not necessarily correct, but it is conceivable how slow the growth rate of the earth crucian carp is!
There is not only one species of crucian carp
But our common crucian carp (earth crucian carp) is not only one species, and even this common crucian carp species is not the best, some earth crucian carp in natural conditions, can grow to several kilograms of huge individuals, although the individual is large, but the meat quality has not declined, then this crucian carp can be called "earth crucian carp"? The bald head thinks they are also earth crucian carp, but we don't know the species of crucian carp.
Engineering crucian carp, engineering crucian carp, also known as Xiangyun crucian carp, is a technical cooperation group headed by Academician Liu Yun of the Chinese Academy of Engineering, cultivating triploid new fish species, the growth rate is very fast, 3 times or more than 3 times faster than the growth rate of ordinary crucian carp. This crucian carp does not reproduce naturally and does not mix with other crucian carp.
The appearance of the engineered crucian carp
There are several kinds of genetically engineered crucian carp, Xiangyun crucian carp is the most famous, although other species of crucian carp, there are also artificial breeding, but not so thoroughly. Crucian carp sold in the wet market are generally this 3-fold crucian carp, although there are many fish eggs in the stomach, but they cannot reproduce naturally.
Crucian carp that has not been artificially selected or artificially intervened can be called "earth crucian carp", and there are many species of earth crucian carp, and the common crucian carp is indeed very small. However, some earth crucian carp species are excellent, individuals are relatively large, and can form huge individuals, but we just don't know it. Because some native crucian carp species are expensive to breed, or crucian carp fry are too expensive, no one breeds them, making it difficult for them to spread in other waters.
<h1 class= "pgc-h-arrow-right" > secondly, what are the "earth crucian carp" with large individuals? </h1>
There are many species of crucian carp, not only the common crucian carp, although we can often catch crucian carp, but this crucian carp species is not excellent, because the growth rate is slow, not slow growth rate meat quality and taste is good. Some species of crucian carp used to be royal tributes, and this crucian carp grows fast, can you say that this crucian carp species is poor? Didn't the ancient emperors know that the taste was good?
Founder silver crucian carp head is relatively small
Crucian carp with excellent varieties and excellent varieties have better meat quality, not only grow fast, but also form huge individuals, such as:
Founder silver crucian carp, Founder silver carp is a specialty of Heilongjiang Fangzheng County, the head is relatively small, the back is thick, cold-resistant, fast growth, the largest individual can reach more than 1.5 kg.
Qihe crucian carp and Qihe crucian carp are one of the "Three Treasures of Qihe" in Hebi City, so they are named Qihe Crucian Carp, Qihe Crucian Carp has a wide back and thick back, and a large flesh fat color is golden or silver. The "Records of History" records that "the Shang king liked to eat ki carp", and later paid tribute to the court of successive dynasties.
White crucian carp, white crucian carp is also called giant crucian carp, Osaka crucian carp, Japanese crucian carp. Native to Lake Biwa, Japan, it was introduced to China in 1976. The color is silvery white, the body is large, the back has a significant bulge like a hunchback, the head of the fish is small, the tail is slender, and the weight can reach about 3 kg.
Dianchi high-back crucian carp, Dianchi high-back crucian carp, body color silver gray, darker back color, lighter belly color. It prefers to colonize and feed in shallow water zones with a fertile substrate, with large individuals up to 3 kg or more.
Ki River crucian carp was once a royal tribute
The individuals of these crucian carp are relatively large, and if you compare them with shoes, they are more than the soles! And the meat is delicious, so do you think they are "engineer crucian carp" or "crucian carp"?
The growing environment is relatively good, in addition to the differences in crucian carp species, the growth environment determines the quality of the flesh, but also determines whether it can grow. Although crucian carp has relatively low requirements for water quality and oxygen content, it is not without requirements. For example, some crucian carp grows in the local meat quality is better, after changing the place, the meat quality may not be guaranteed.
There is also external intervention, although crucian carp species can form huge individuals, but they have no chance to grow. Environmental pollution coupled with indiscriminate fishing, want to grow up can not be said unrealistic, can only say that it is too difficult, no matter what species of crucian carp will appear huge individuals, but this probability is too small and too small.
The white crucian carp is native to Japan
Therefore, it is not only the crucian carp, it is the real crucian carp, many crucian carp have more flesh than the crucian carp, and can form a huge individual, but we do not let it grow! If the catch is reduced and the water quality improves, crucian carp is prone to huge individuals and the meat quality is also very delicious.
<h1 class= "pgc-h-arrow-right" > Finally, why are "good breeds" of crucian carp uncommon? </h1>
Some crucian carp species are excellent and can form huge individuals, so why is no one farming, or uncommon? This involves the cost of farming and the perception of crucian carp species.
The high cost of breeding, the sale of crucian carp is a commodity, it can be said that "in the case of breeding, no matter what species of crucian carp, the quality is difficult to guarantee"! Because businessmen are pursuing profits, there are no interests or the interests are relatively low, who wants to do it? If there is a high-interest farming method, how many people are willing to give up high interests and earn a small amount of profit?
To cultivate crucian carp, it is necessary to control costs and increase efficiency
Engineering crucian carp or some other species of crucian carp grow fast, breeding time is short, breeding cost is low and fast, who will breed crucian carp with high cost and slow effect? And the price of crucian carp is about 10 yuan a catty, has been deeply rooted in the hearts of the people, breeding high-quality crucian carp, the price must rise, whether anyone is willing to buy, or a problem, because it involves credibility!
Therefore, it is difficult for high-quality crucian carp to have a market, people's psychology has been fixed, and it is difficult to change the breeding model and business model. The crucian carp we buy in the wet market is generally a quick crucian carp that has been selected, and the quality of the publicity is very good, but whether it is good or not, it also needs to be tasted by the buyers themselves!
Not knowing, not knowing is also a problem, even anglers who often fish, they have "little knowledge" about crucian carp species. Because I always feel that the so-called earth crucian carp, there is only one kind, that is, the common small crucian carp, all feel that this crucian carp does not grow much, in fact, if the indiscriminate fishing is reduced, they can also grow up and form a huge individual.
There are so many species of crucian carp that it is difficult to know
When the bald head was a child fishing, half a pound of crucian carp was common, and 1-2 pounds of crucian carp could occasionally be encountered, and there was no engineering crucian carp at that time. No one releases crucian carp in either ponds or rivers, and all crucian carp are wild.
There are many species of crucian carp, not large individual crucian carp are "engineer crucian carp", some anglers say that crucian carp back height, or body width, or fish scales are not the same, it is not wild, in fact, this statement is very general, because some crucian carp species themselves have high backs, or relatively wide. I just think that the crucian carp is relatively large, that is, the engineering crucian carp, this statement is wrong!
Bald summary: In fact, for anglers, if fishing in the wild, there is no need to worry too much about the species of crucian carp, because no matter what kind of crucian carp, it is not easy for them to grow up. In addition, crucian carp grown in the wild, there is no copper odor added, although the species of crucian carp is different, but the meat quality is still good, compared to the farmed crucian carp taste much better.
This is the best result if you can catch a large individual "crucian carp" or other excellent species of crucian carp. If the species of crucian carp is not good, but the individual is relatively large, do not be discouraged, because they grow very slowly in the wild, the meat quality is at least guaranteed, the key is to catch or unknown, can not catch everything is white, you say? #谣零零计划 #
