Cambodian villagers catch the world s largest freshwater fish weighing 300 kilograms, why does this

Cambodian villagers catch the world's largest freshwater fish, weighing 300 kilograms, this fish can grow so big because of natural conditions, according to the previous scientific records of the Yangtze River white sturgeon, under normal circumstances can reach more than 300 kilograms of weight, the normal body size is about 2 3 meters. Secondly, wandering in the deep sea, he is basically in a state of not being restrained, so it is normal to grow so big. Moreover, small fish can eat all kinds of small fish or shrimp when they grow in fresh water, and their lives are relatively rich, and it is normal to grow within a few meters.

It is understood that this is because of the natural condition

It is understood that Chinese biologists have recorded a king fish in the last century that is even bigger than this. It is known that normal such fish is capable of reaching a body weight of 300 kg, and can reach a body size of 2, 3 meters. This means that the growth of this fish is normal, but we have never seen such a large fish before, so there will be a lack of strong evidence.

This is a type of fish that grows naturally in its natural state.

Wandering in the depths of the sea, unbound

Generally, this kind of fish ** is caught because of negligence, and if no one has gambled, it may grow bigger than it is now. This size is estimated to exceed several hundred kilograms, this is wild and not artificially raised, and the artificially bred ones will not be so big, so this giant fish has also become a giant. In the deep sea, the nutrients are also relatively sufficient, and it may grow for many years without salvage, so it is not surprising that it has grown into this size.

Eating small fish and shrimp makes life richer

It is known that there is information about the environment of this place, and even sociologists believe that in the near future, it is estimated that there will be a larger species than this 300-kilogram fish. First of all, these small fish are in the shape of eating by fish and shrimp, and when they grow up, they will eat more large fish. Relying on the ecological environment in this river, the formation relies on a continuous supply of food, so it is not surprising that the giant fish are large.

Because it has no natural predators and eats abundant food, this fish has become so big when it keeps eating.

Because there are no fishermen in the area where this fish lives, and there are people who throw food at the fish.

Cambodian villagers recently caught a stingray weighing 300 kilograms. The first is the food they eat, small stingrays can feed on small fish and plankton, but when they grow up, these small foods are difficult to satisfy their appetite, and giant stingrays need a lot of medium-sized food to support themselves. These large numbers of medium-sized fish must rely on the Mekong's good ecological environment to grow, so as to ensure that the giant stingrays can have a continuous supply of food.

But such an abundant food chain** doesn't just feed the giant stingrays, which means that other giant fish will also benefit from it, so this will lead to an endless stream of giant fish.

According to the People's ** Overseas Network Weibo news, local Cambodian villagers recently caught a 300-kilogram stingray in the Mekong River, which needed more than a dozen people to drag ashore. According to the researchers, it is the largest freshwater fish currently known in the world. Cambodian villagers catch the world's largest freshwater fish, how big is this fish?

1. How big is this fish?

You know, Cambodian villagers caught a giant stingray as a femaleThe female, long and wide and weighing 300 kilograms, took more than a dozen people to drag it ashore, according to researchers, as the largest freshwater fish known in the world. It has been electronically tagged and put back into the river, where scientists will test its movement and behavior. The research value of such a large fish for delicious enjoyment far outweighs its edible value.

According to the Mekong River Commission, the Mekong River is home to the world's third-largest diverse fish population, despite threats such as overfishing, pollution, saltwater intrusion and sediment depletion.

2. New quality of water resources

In fact, it is a good thing for us that the aquatic giants recorded by our ancestors have reappeared, not only to return to the old road of how to rationally develop, utilize and protect water bodies and aquatic resources, but also to change our attitude towards aquatic life - only the rich diversity of the deep water ecological environment can nourish a larger aquatic life population, and only a healthy and stable population can give birth to these magnificent wonders.

3. Mekong River

With a total length of 4,200 kilometers, the Mekong River is one of the most powerful rivers on the planet. It is 1,900 kilometers long and flows through the territory of Laos, so Laos is also considered to be a country ruled by the Mekong River. Once upon a time, relying on the abundant and diverse fish resources of the Mekong River, Laos once became one of the regions with the highest freshwater fish production in the world.

Postscript: Summer is a good time to eat fish, many fish are close to the spawning period, the body has accumulated a lot of fat and nutrients, the body is fat and firm, so the taste of the meat is the most delicious, there is a sweet feeling to eat, people are hot and dry in summer, and the cooking method can choose more steaming, stew, etc., which can supplement the lack of vitamins and minerals in our body. Foodies, rush.

The fish weighs 300 kilograms and needs more than a dozen people to be dragged ashore, making it the largest known freshwater fish in the world. The fish are female, and scientists test their movements and behavior, which means that the Mekong waters are very healthy, free from overfishing pollution and saltwater intrusion and sediment depletion.

This fish is very large, weighing 300 pounds, and is the largest freshwater fish in the world, which is very surprising.

It can be said that it weighs up to 50 pounds, and lying flat on it can be the volume of a house. Scientists have found that he has lived for thousands of years.

Local Cambodian villagers catch a 300-kilogram female stingray in the Mekong River, the largest freshwater fish ever foundThe fish has been electronically tagged and put back into the river, and scientists hope to protect the local environment and wildlife through the fish's activities and behaviors.

The Mekong River is the seventh largest river in the world and the largest in Southeast Asia. The climate of the region is tropical monsoon, with an average minimum temperature of 23 degrees, an average maximum temperature of 32 degrees, and an average annual rainfall of 3000 mm. It is hot and rainy, the water network is dense, and the soil is deep and fertile.

It is very suitable for the growth and reproduction of plants and animals. The ecological diversity of the Mekong River is second only to that of the Amazon Basin. There are more than 1,700 species of fish here.

Half of the world's largest freshwater fish are found here, including giant stingrays, giant Siamese carp, giant stingrays, Mekong giant catfish, etc. These fish can be more than three meters in size and weigh more than 300 kilograms. The locally caught fish is the giant stingray, one of the four major fish in the Mekong River.

Giant stingrays, which live mainly in the Mekong River, are one of the largest freshwater fish in the world, and in the wild, they can reach a body size of up to 5 meters, weigh up to 600 kilograms, and have a brown body. At present, scientists do not know much about the habits of this fish. This fish has lived on the earth for millions and is of great significance for studying the evolution of the Earth's ecosystems and species.

Stingray is also known as red ray, hearing this name, many friends should be very unfamiliar, fishermen in many areas usually like to call stingray or catfish. The main reason is that the overall body shape of the stingray looks like a circle, which is very similar to the shape of the fan or straw hat that is common in the daily life of residents. So, fishermen gave these names to the stingray based on its shape.

It is a meter-long stingray. It is the largest freshwater fish found now, and the previous largest freshwater fish was also a catfish found in the Mekong River.

600 pounds. The actual weight of this fish has reached 600 catties, which is equivalent to the size of several adults.

Approximately 300kg. The body of the fish is very round, very large, and very special. It's called a stingray.

The Mekong River originates in China's Tanggula Mountain, is called the Lancang River in China, and flows through five countries: Myanmar, Laos, Thailand, Cambodia and Vietnam. During the rainy season, a large number of plants on the shore are submerged, and food is abundant, and many fish come here to feed. And there are more fish living in the Mekong than any other river in the world.

Therefore, it is important to strengthen the nature protection of the Mekong River, not only to protect the diversity of life and fish, but also to ensure the sustainable development of the Mekong River Basin.

This fish is particularly large, weighing a total of 300 catties, and the area is also relatively large, accounting for 7 square meters.

The fish weighs 300 kilograms and requires more than a dozen people to be dragged ashore, making it the largest known freshwater fish.

Good water quality, sufficient oxygen, sufficient fry, healthy feed, etc. are all important conditions for raising freshwater fish.

Good water quality is the most important condition for freshwater fish farming, because freshwater fish need pure and pollution-free fresh water, and the water quality must be guaranteed, if the water is polluted or the harmful substances in the water exceed the standard, it will not be able to provide a favorable living environment for freshwater fish, and it is not conducive to the breeding of freshwater fish. The best water for breeding freshwater fish is live water, so that the fish can absorb richer nutrients in the water, which will make them grow faster.

Sufficient oxygen in the water is also an important condition for freshwater fish farming, not only to ensure the quality of freshwater, but also to ensure the content of oxygen in freshwater, not to let it be lower than the standard value, in the process of breeding found that the water oxygen is insufficient food to increase oxygen in time, only in this way can freshwater fish breathe smoothly in the water in order to improve the aquaculture production of freshwater fish, will make freshwater fish grow bigger and healthier.

Having high quality and enough fry is also an important condition for freshwater fish farming, and then prepare the pond and fresh water to buy high-quality fry, directly put in fresh water, must ensure the number of fry, under normal circumstances, the yield of freshwater fish should be about 4 times that of the fry. When breeding freshwater fish, you can also mix adult fish, which will not affect the normal growth of fish and can expand the fish, and the species will increase the production of freshwater fish and save breeding costs.

High-quality feed is also an important condition for raising freshwater fish. When large water fish are raised, they only rely on microorganisms in freshwater and cannot meet their daily needs, so they must be given to provide healthy and high-quality feed. When providing feed for freshwater fish, do not ignore the proportion of ingredients, ensure balanced nutrition, and do not put moldy and spoiled feed, otherwise it will affect the normal growth of freshwater fish and the production of freshwater fish.

Freshwater fish are reared under conditions that require a relatively large pond with food and oxygen and regular water changes.

You need a place with grass and soil, and this kind of place can make them extra fat.

Warm water fish farming, the general water temperature is 15-30, such as carp, grass carp, silver carp, bighead carp, crucian carp and tuantou bream, etc.; Cold-water freshwater fish farming: generally the appropriate temperature is 10-20, such as rainbow trout, fine-scale fish, etc.; Hot water fish farming: the general temperature is 18-30, such as tilapia, freshwater pomfret, etc.

Cambodian villagers caught the world's largest freshwater fish in the Mekong. This freshwater fish is a stingray, weighs about 300 kilograms, is nearly 4 meters long, and requires more than a dozen people to drag it ashore.

In my personal opinion, the fact that this stingray can grow up to 300 kilograms is closely related to its own luck; In the process of growth, it not only escaped the predator hunting, but also successfully avoided the fishermen's fishing and water pollution damage. After growing to a certain size, it has no natural predators in natural waters, and then as long as it is not hunted by humans and is not affected by water pollution, it can continue to grow until it dies.

The vast majority of fish will gradually grow in size over time. This stingray was very lucky, and most of its companions have died as it grows up. may die in the mouth of a natural enemy and become a part of the nutrition of the other party's growth path; It can also die from water pollution, and it may also be caught by fishermen and become a meal on the plate.

This stingray, fortunately avoiding all risks, was able to grow freely until it weighed 300 kilograms and was nearly 4 meters long. Without this luck, this stingray would not have grown to such a size, and would have died before he was a minor, just like his other companions.

When the stingray grows all the way to a certain size, it will become the dominant body in the water, and there will be no more aquatic life, which can threaten its life. The big guy with a body size of nearly 4 meters, put in the Mekong River, is a behemoth, and the rest of the fish in front of it can only be the younger brother, except for being bullied, he definitely does not dare to compete with it.

After there are no enemies in the ecological environment, the later growth of stingrays will be smooth sailing, and there will be no more stumbles. Even if it is caught by humans, it may be easy to escape, and it is not easy to catch such a big guy.

The discovery of this fish was exciting and broke the previous record for the heaviest freshwater fish. Fortunately, after the stingrays were measured, they were marked and finally released back into the Mekong River.
