Introduction: Is the bluefish the fastest growing among the "four big fish"? How big is the maximum growth? Why?
Although the bluefish is now a relatively rare fish in the market, many young people do not even know it. However, in the circle of fishing friends, bluefish are very popular.
So which of the "four big fishes" that mainland folk often say grows the fastest? How big can it grow? Let's explore it together.
The bluefish in the "Four Big Fishes"
To figure out who among the four big fish grows the fastest, it is necessary to first understand which four kinds of fish the "four big fish" refers to.
The so-called "four big fish" refers to the environment of these four freshwater fish in the wild is generally difficult to reproduce naturally, and it must be considered that the breeding environment can reproduce and grow in large quantities. It is also because human intervention is required, just like farmers raise chickens and ducks, so they are called "domestic fish".
From ancient times to the present, the four major fish are also the four fish species with the longest history and the widest range of culture in the mainland. The four major fish recognized in the folk are blue carp, grass carp, silver carp and bighead carp (silver carp).
Some people are very curious, how come the four big fish do not have carp? Isn't this fish also widely farmed, and has a very long history of farming?
In fact, there is no carp in the four major fish, as to why it may be related to the strong reproductive ability of the carp, even if there is no human interference, it can still reproduce in large quantities in the wild environment.
Among the four major fish, if you want to say that the fastest growth rate, some people say grass carp, some people say white carp and silver carp. In fact, the real fastest growing is the bluefish.
It is undeniable that in the early stage, the growth rate of grass carp is much faster than that of bluefish, that is, the juvenile stage, during which grass carp can grow one or two pounds a year.
But when the bluefish grows a "blue fish stone" - the keratin hyperplasia in the mouth used to help crush hard foods such as snails, its growth rate is like an open hanging, it can grow several pounds a year, and if there is enough food, it can grow an average of four or five pounds a year.
This is because in the early stage of bluefish, they mainly feed on benthic animals, dragonfly larvae, rocking mosquitoes and so on. After having the blue fish stone, it began to prey on a large number of mollusks in the bottom of the water, especially like to eat snails, mussels, clams, clams and so on.
Although these animals have a hard shell, the blue fish eat them like we humans snort melon seeds, eat them and bite the shell and spit it out, and then suck the meat in and eat it, which is very easy. It is also due to the feeding habits of the bluefish, which not only grows fast, but is also the largest of the four largest fish.
How big can a bluefish grow?
The reason why it is said that the bluefish is the largest of the four major fish is also based on evidence. First of all, from the perspective of feeding habits, silver carp and silver carp are typical plankton feeding fish, although their early growth rate is fast, but often grow slowly to about seven or eight pounds, these two kinds of fish are generally difficult to exceed 20 pounds.
Although the grass carp is relatively large among the four large fish, it is after all a kind of fish that prefers vegetarian food, and the growth rate gradually slows down after adulthood, and it may not grow a pound a year in the later stage. Therefore, it is not surprising that the general grass carp weighs more than ten pounds, and the largest can grow to more than 40 pounds, but it is relatively rare.
As for the bluefish, in recent years, anglers across the country have caught some large bluefish, such as thirty or forty pounds, fifty or sixty pounds. But this is not the limit of the bluefish, the largest recorded bluefish is 114 kilograms.
In July 2005, an oversized bluefish was caught in Jinniu Lake in Liuhe District, Nanjing, Jiangsu Province, which was 1.76 meters long, taller than an average adult. And after weighing, it scared the people of the fishing team, which was 114 kilograms, that is, 228 kilograms, such a large weight was really fat into a pig.
Also because this is the largest recorded blue fish, this blue fish caught by the fishing team, broke the historical record, so it was then made into a specimen by the Jinniu Lake Scenic Area and placed in the scenic area.
In fact, as early as 2004, it was also in the Golden Bull Lake, and a huge blue fish was also caught, which was 1.76 meters long at that time, but weighed 106 kilograms, and it was also made into a specimen and placed in the scenic area.
Like the blue fish we usually see, it generally weighs a few pounds, and the large one is more than ten pounds. However, this giant bluefish weighs 114 kilograms, which is more than 20 times heavier than the bluefish you usually see, which is really a huge thing!
In addition, in 2012, at the Tianzigang Reservoir in Gaoyu Town, Anji County, Huzhou, Zhejiang, a blue fish with a length of 1 meter and 92 meters and a weight of 208 kilograms was also caught. Although it is not the largest bluefish, it is the longest.
Moreover, in recent years, bluefish like 30 or 40 kilograms are often caught, among which there are many large bluefish in Fuxian Lake in Yunnan Province, and there are countless large blue fish that have been caught more than 100 kilograms. The largest of these also weighs 65 kg.
Why do bluefish grow so big?
Some people are very curious, why can the bluefish grow so big? In fact, this also has a lot to do with their longevity.
Bluefish is a very long-lived fish, and it should be the longest-lived of the four major fish. The largest blue fish previously caught in Nanjing's Jinniu Lake has survived for at least 40 years after experts' professional instrumentation.
Unlike many animals, fish grow in weight with age, but only slower in the later stages.
In addition, the bluefish is originally a carnivorous fish, its size is large, the strength is also large, and there are basically no natural enemies in the water. In particular, the large blue fish weighing dozens of pounds is the general existence of the "little bully" in the water.
Moreover, the bluefish also have a habit, that is, they eat a lot, but do not like to move, this hobby is similar to pigs, eat and sleep, hungry continue to eat. The same is true for bluefish, they will be motionless under the water after they are full, eat more, and have less activity, so it is easier to grow meat.
It is also because of the size of the bluefish, the meat is very delicious, in the past the blue fish also had a nickname "fish", "ghost fish", etc., because many people often went to the water to pick up the big water washed out of the blue fish and died.
After all, this kind of fish is too big, even if the average person has good water, it is not an easy task to drag dozens of pounds of fish into the water. If the bluefish is not completely dead, a tail pounces on it, at least it is seriously injured.
However, such large bluefish are also rare, especially in recent years, large blue fish are becoming less and less, such as the weight of more than 100 pounds to live at least 40 years or so, such is rare.
