Before reading the article, warm tips: happy fishing, safety first; civilized fishing, cherish the environment; fishing for entertainment, juvenile fishing!
Recently, when fishing in the Henan and Shandong sections of the Yellow River, fishing in the Yellow River and its tributaries, they caught fresh fish species, a new fish that had not been caught in many years.
< h1 class="pgc-h-center-line" > what new fish the anglers caught</h1>
According to an angler in Henan, although the bait he used was for carp fishing, when he caught this fish for the first time, he spat out some small fish scraps from the fish's mouth, so it can be determined that it is a carnivorous fish.
When caught, look at the appearance of the fish on the surface of the water, the angler thinks it is a perch, but after landing, looking at the teeth in the mouth and the pointed head, the slender body, and feel that it is not the same as the perch, so the angler suspects that it is a pike.
Coincidentally, in addition to the fishing friends in the southern section of the Yellow River, the anglers in the eastern section of the Yellow River also caught this fish.
In addition to catching this fish in the Yellow River, there are rumors of fishing in some other waters, and even my hometown linyi city has fishing friends, but I have not seen it, nor have I caught it.
According to our Linyi fishing friend Mr. Qi, he caught several strange new species of fish while fishing in an abandoned breeding pond.
"The individuals of several fish are not large, look like mandarin fish, but the body is narrow and thin, the head is longer than the tip of the mandarin fish, and there are teeth in the mouth, which is not much different from the mandarin fish we usually catch," Mr. Qi said.
Seeing the picture of the fish, many netizens also left a guess about the name of the fish, some people think that it is a mandarin fish, some people think it is a kind of perch, and some people think that it is a white spotted pike living in the alpine zone.
Out of curiosity, after seeing the picture, I deliberately searched the Internet for all varieties of mandarin fish, sea bass, and pike, and found that they were not!
This fish is called pike perch, because of the long teeth commonly known as toothfish, puppy fish, belongs to the order Perch family Pike perch genus, mainly distributed in the Aral Sea, Black Sea, Caspian Sea, Baltic Sea and other rivers and lakes. In the early 1960s, it spread from Central Asia to our country, mainly distributed in the Ili River system and irtysh River system in Xinjiang.
Although the distribution range of pike perch in China in the early 1960s was small, but because of its rich nutrition, less thorns and tender meat, rapid growth, strong adaptability, and high economic value, at present, in many provinces and cities in China, large-scale stocking and breeding has begun to appear. At the same time, this fish is highly adaptable and can be economically farmed almost all over the country!
<h1 class= "pgc-h-center-line" > the habits of the pike perch may have made the Yellow River a Luya "paradise"</h1>
Looking at the commonly known as toothfish and puppy fish, we can guess that it is a fierce predatory fish, and the ferocious predatory fish is the main target fish of Lua anglers when fishing.
First, the living conditions of the pike perch
Although it is a cold-water fish, it is adaptable and can adapt to water temperatures ranging from 0 °C to 33 °C, while the optimal temperature for its growth is 12 °C to 18 °C. Whether it is the water temperature range it adapts to, or the optimal growth temperature, it can be achieved in most parts of China, that is to say, most areas are suitable for its survival and can be farmed.
Second, the main food of the pike perch
Pike bass are medium-sized fish in freshwater or brackish freshwater carnivorous fish, with adults reaching a body length of 50 cm to 130 cm and a weight of about 8 kg to 12 kg, with a maximum of more than 20 kg.
The fry stage mainly feeds on aquatic insects such as rotifers and arthropods, and will slowly turn during the growth process to feed on large zooplankton and benthic organisms, such as water earthworms, red worms, large fleas, etc.
When the pike perch grows to more than 2.5 cm, it can prey on the seedlings of other small fish and shrimp, and in the hungry state, it can prey on fry that grow two-thirds of its body, and if food is scarce, it will also kill each other, preying on weaker individuals in the same kind.
Third, the life habits of the pike perch
Although pike perch are carnivorous predatory fish, they are different from the common catfish and blackfish, they like to live in groups and have the habit of swimming in groups.
In addition, the living water layer of the pike perch is also wider, although it belongs to the middle and lower layers of fish, like to hide in the deep water area, but it can also live in the middle and upper layers of the water. In addition, they will also follow the changes in the water level of the water, change their own life, foraging water layer, life, foraging water layer range jumps greatly.
Usually like to hide in the sandy and slightly flat bottom, when foraging, like to the water flow is relatively gentle, there are obstacles in the water, such as trees, rocks, bridge piers near the water; the bottom of the ditch junction, sometimes swim to the nearshore aquatic grass foraging, hiding.
Fourth, the feeding habits of the pike perch
In natural waters, pike bass belong to the lower and middle classes of fish and prefer to move in stable water layers in deep waters. In addition, like most predatory fish, the pike perch has a habit of nocturnal outings, preferring to come out in the evening or at night to feed. In addition, although they are fierce carnivorous predatory fish, they are more vigilant when foraging, and when they encounter external disturbances, they will quickly escape back to the bottom of the deep water.
When foraging for food, the shuttle perch moves quickly and fiercely, often aiming to bite the prey first. It is said that in fishing, it can often leave bite marks on lead hooks and soft baits!
Through the above 4 points, we can have a simple understanding of the habits of the pike perch. According to these habits and habits of pike perch, anglers can find that they are a good Lua target fish!
If their populations in the Yellow River breed and there are more adults, the Yellow River may become a Lua "paradise" for anglers.
< h1 class = "pgc-h-center-line" > whether the pike perch will be widespread in China</h1>
As mentioned above, pike perch is a medium-sized carnivorous predatory fish and belongs to the introduced fish species, so they have few natural enemies in China's natural waters.
In addition, the pike perch has a short maturity time, fast reproduction, rapid growth, and low requirements for breeding water temperature! Generally, 3-year-old fish can mature and spawn, and in high-temperature waters such as Guangdong, 1-year-old fish can mature and spawn.
The lower limit of breeding water temperature is about 7 °C, the upper limit is about 20 °C, and the water temperature most suitable for spawning is between 12 °C and 18 °C.
Although it is a one-time spawning fish, the amount of eggs laid at one time is high, and the single tail weighs 2 to 3 kg of pike perch, and the amount of eggs in a single spawn is 300,000 to 400,000! In addition, their growth is also relatively rapid, and under the condition of sufficient food, they can grow to about 1 kg a year in Guangdong.
The originally farmed pike perch was caught in Henan, Shandong, and even some other natural waters, which made some netizens who were concerned about ecological balance a little worried. Worry if it will become the next tilapia, the next scavenger! Worried that this imported exotic fish species will not flood the Yellow River or even the whole country?
Of course, the netizens' worries are not unreasonable! After all, in addition to strong adaptability, rapid reproduction and rapid growth, the shuttle perch has few natural enemies in China's waters! Once the population reaches a certain number, its population will spread rapidly, even surpassing tilapia and scavengers.
However, most netizens are not worried about some, and even some fishing friends are inquiring about fishing spots, saying that "my Luya rod is hungry and thirsty."
Why are most netizens not worried that the pike perch will flood?
It's mainly our cuisine and the pike perch itself, making it difficult for it to have a chance to flood!
When it comes to food, I've always believed that our country's cuisine is the best! When it comes to "foodies", I have always believed that our "foodies" are the most able to eat, and they are always at the top of the "food chain".
Some netizens may ask, if this is the case, why are tilapia and scavengers still flooding in some areas of the south?
In fact, the flooding of tilapia in some areas of the south is not really a large tilapia, but a small tilapia commonly known as "nail non". They are not big or delicious, so almost no one eats them!
As for the scavenger, in addition to its ugly name and ugly appearance, it is also related to its living environment, foraging habits, food, and its own meat is difficult to handle and not delicious, resulting in it being disliked and uneaten.
On the other hand, the shuttle perch itself is a carnivorous predatory fish, and has certain requirements for the quality of survival water. At the same time, the meat has fewer tender thorns, extremely high nutritional value, and the protein content exceeds 20.53%, which is higher than that of the valuable fish species mandarin fish, and the edible effect is obviously better than that of mandarin fish! The content of the other 5 fresh amino acids is also higher than that of rainbow trout, which is known as the "freshwater fish king".
In addition, the artificially farmed pike perch, the sales price in the market is higher, depending on the region, between tens of yuan per kilogram to nearly 100 yuan per kilogram!
Can we let such a delicious and precious pike perch be flooded?
