CATDOLL : CATDOLL: The world's largest catfish. The giant catfish can weigh up to 600 kilograms (it is a highly endangered species).

1. The world's largest catfish Giant catfish can weigh up to 600 kilograms (a highly endangered species)

Catfish is a carnivorous fish, and one of the more ferocious freshwater fish. Some species of carnivorous fish can grow very large, such as the giant catfish. Someone once caught the largest catfish in the world, which weighed 586 kilograms and was 2.7 meters long. For a long time, it was the largest freshwater fish ever caught.

The giant catfish weighing 586 kilograms is a common edible fish. Most catfish we eat are bigmouth catfish, bearded catfish, leather bearded catfish, etc. They are not only easy to breed, but also taste good. They are a common edible fish. For most ordinary people, the largest catfish they have seen is only about 10 to 20 kilograms. It is hard to imagine what it looks like when it weighs hundreds of kilograms.

There is a kind of giant catfish, which can generally grow to several hundred kilograms, but it is not common now. Due to human fishing and water quality and other reasons, their numbers are becoming increasingly scarce and they are already highly endangered. The largest silver carp that has been clearly recorded as being caught is a giant catfish weighing 586 kilograms and 2.7 meters long. It can be said to be the largest catfish in the world.

This giant catfish, which is 2.7 meters long and weighs 586 kilograms, is a female Mekong giant catfish caught in Thailand in 2005. This Asian giant catfish can grow to more than 500 kilograms as an adult, but in fact, this catfish is usually caught before it reaches adulthood, and only a few can actually grow up.

Giant catfish is a fish with extremely high nutritional value and very tender and delicious meat, so it was once caught in large quantities by people and its number has become scarce. Giant catfish is considered the most endangered fish in Southeast Asia. After 2005, villagers in Thailand and Laos promised not to kill giant catfish anymore. In the following decade, the world has made great progress in protecting giant catfish.

The largest giant catfish caught was a 586-pound giant catfish. Their average lifespan is 30 years. An ordinary giant catfish can grow to 1.3 meters long and weigh more than 240 pounds. Because this giant catfish is so large and carnivorous, there are often rumors that giant catfish eat people. Most of these rumors are false. For example, the 2011 Yangzhou giant catfish eating people incident was actually just a few technicians dissecting a whale shark to make a whale shark specimen.

2. What is the best hook and rod for fishing silver carp?

The best hook for silver carp is the Ise-type hook. When fishing for silver carp, the choice of hook type is an important aspect. It is best to choose one that is based on the shape of the silver carp's mouth. According to the characteristics of their mouths, it is best to use a hook with a wider mouth, a shorter hook handle, and a thicker hook. The fishhook that meets these requirements is the Ise-type hook, which is not easy to escape, has a relatively high strength, and is also easier to buy. When choosing a hook, you should also pay attention to the model. It is recommended to choose a size 8-10.

1. What kind of fishhook is best for fishing silver carp? Silver carp is a freshwater fish that lives in various forms of freshwater in my country and is widely distributed. Whether it is artificially raised or in wild rivers, there are a large number of silver carp, and these silver carp can be the target of fishing. When fishing, various fishing gears are very important, and fish hooks are one of them. There are many types of fish hooks, and their shapes are different, and the differences are sometimes quite large. Various parts, such as the hook gate, hook handle, hook gate, etc., all need to be paid attention to, and fish hooks should be selected based on these.

Specifically, according to the shape of the silver carp's mouth, it is best to choose a hook with a wider mouth, a shorter hook handle, and a thicker hook. Fish hooks that meet these requirements, such as Ise-ni hooks, are very effective when fishing for silver carp. Therefore, in most cases, if there are no special requirements, it is okay to use Ise-ni hooks. Of course, in addition to Ise-ni hooks, some other fish hooks may also meet this requirement, such as small rock hooks, which are effective and not easy to escape fish. No matter what kind of fish hook, you can use 8 to 10. When fishing for the largest individual silver carp, it is also possible to use 10 or above.

2. Which rod is good for fishing silver carp? As mentioned above, when fishing silver carp, you should decide the fishing hook according to the body shape and mouth shape of the silver carp. In addition, other fishing gear is also very important. The fishing rod is the main tool used when fishing silver carp, and you should also pay attention to the selection. Silver carp lives in freshwater basins, which means that the place for fishing is in freshwater basins. Generally speaking, in such waters, it is more appropriate to use a hand rod. The hand rod is the most commonly used rod, and the effect of fishing silver carp is good.

Generally speaking, when fishing for silver carp with a hand rod, it can be used in most waters. The specific length and hardness need to be paid attention to. Generally, a longer rod is used, such as one over 5.4 meters. The hardness must also be considered, and a slightly harder fishing rod is more appropriate. However, when fishing for silver carp in some waters, the situation is relatively special. For example, some freshwater basins are very vast. In such waters, a hand rod is relatively not particularly suitable. At this time, you can use a fishing rod suitable for fishing in larger waters, such as a rock fishing rod.

3. What are the "four major carps" that rural elders often talk about?

The origin of the four major carps probably dates back to the Tang Dynasty. They are black carp, grass carp, silver carp and bighead carp. Let's take a closer look:

Black carp: Its body is cylindrical with a round belly. It is dark blue with a darker back and a grayish white belly. All fins are grayish black. It looks like a grass carp, but its head is smaller and slightly pointed, and its body is stronger. Its belly is grayish white, and the rest is dark blue, especially its fins, which are darker. Its scales are larger. Black carp is not active, and it is more adaptable to fertile water than grass carp. It lives at the bottom of the water. It often swims in the middle and lower layers of the water, on the shore and at the bottom of the water to find food. Its food is mainly mollusks such as snails and river clams, and it also eats artificial bait. Black carp grows fast, is disease-resistant, has fewer bones, thick meat, and is high in fat. It is a high-quality edible fish.

Grass carp: Grass carp, also known as silver carp, is long and slightly cylindrical in shape. Its body color is tea yellow with gray. Its pectoral and pelvic fins are orange-yellow. Its forehead is relatively flat, its ventral side is relatively soft, and its scales are relatively large. Grass carp is lively and will lurk around the pond if it is slightly disturbed. It likes to live in relatively light and thin water bodies, living in the water, the lower layer and the shore. Grass carp is a typical herbivorous fish, mainly feeding on aquatic plants and terrestrial aquatic plants, and also eating artificially fed bait. Grass carp is a large fish, and its food intake is 40% of its normal body weight. It grows quickly and can reach a maximum weight of more than 40 kilograms. It is the most popular and excellent variety.

Silver carp: Silver carp is also called silver carp. It has a flat body, silvery white sides, light black back, and small phosphorus. Silver carp is lively and good at jumping. It likes to live in warm and fertile water bodies and inhabits the middle and upper layers of the water. It is an upper layer fish. It mainly filters plankton. In artificial breeding ponds, it also eats cake residue, bran, bran and distiller's grains. Silver carp has few diseases and grows fast. The largest individual in free water can reach more than 15 kilograms.

Bighead carp has a flat body and a large head, which accounts for about one-third of its body length. Its abdomen is round before the base of the pelvic fin, and there is an abdominal ridge from the back to the anus. Its body color is darker, with irregular black stripes. Its back and upper sides are slightly black, its abdomen is silvery white, its fins are gray, and its scales are small. Bighead carp is in the middle and upper layers of the water, and feeds on zooplankton in the water. Bighead carp is much more popular than silver carp, just because it has a fat head. The delicious "chopped pepper fish head" is made with its fat head.

The above four kinds of fish are all freshwater fish. They have a long history of breeding in my country, with a large breeding area and a large number of breeding. Therefore, they are called the four major carps. They are also the most commonly eaten fish in some places.

Silver carp, black carp, grass carp and bighead carp are the four major carps often mentioned by rural elders. They can improve the utilization rate of bait and increase fish production.

Refers to black carp, grass carp, silver carp and bighead carp. These four kinds of fish are relatively easy to raise and have gentle personalities, and rarely compete for food.

The four major carps refer to large economic fish farmed in freshwater, namely grass carp, black carp, silver carp and bighead carp.
