CATDOLL : CATDOLL: It is said that king crabs are rampant in the Antarctic waters. Why are Chinese fishing boats bringing back so few?

King crabs belong to deep-sea crabs, which can survive at depths of up to 850 meters and in water temperatures between 2-5°C. Chinese fishing boats are not able to reach the Antarctic under the conditions, and the same is true for fishing boats from other countries. Even if there are king crabs brought back, they are not brought back by fishing boats. Under such harsh conditions, human survival is a problem, so how can people catch king crabs? !

King crabs are crustaceans belonging to the genus Paralichthys of the family Lithocaridae. They belong to deep-sea crabs and mainly live in the cold waters of the North Pacific. They prefer an environment with a temperature of 2-5°C. It is currently known that king crabs live on the seabed at a depth of 1,100 meters.

In the original Pacific Ocean, king crabs were affected by natural enemies, such as giant octopuses and wolffish, and most importantly, human fishing, so their numbers have been stable. But after arriving in the Antarctic, people didn't know that there were king crabs here, and there were no natural enemies that could hunt them. The most important thing is that king crabs have a strong reproductive capacity: a female king crab has the ability to reproduce since it reaches sexual maturity at around 4 years old, and can reproduce continuously for about 20 years (average lifespan 25 years), and a female king crab can lay nearly 10,000 eggs at a time.

Therefore, without the threat of natural enemies and fishing, and with the super reproductive capacity of king crabs, they have successfully reproduced "millions of them" in the Antarctic waters. Moreover, since the first discovery in September 2011, the scientific expedition team found them again this year. This time, the depth of the sea water where they live has been reduced to about 1,000 meters, and the number has also increased from more than 1 million to millions.

King crabs are found in the cold waters of the Pacific Ocean, and they have a strong reproductive capacity, so why are their prices so high? The main reason is the cost of catching them.

First of all, king crabs belong to deep-sea crabs, so if you want to catch them, you must have deep-sea fishing equipment, which is one of the costs. Secondly, king crabs mainly live in cold waters, where there are cold winds for most of the year, which makes it very difficult to catch them. In addition, the crew's salary is relatively high when working under such harsh conditions.

Third, the price of live king crabs is relatively high, so after being caught, they need to be properly stored to ensure their freshness. This cannot be solved by simply keeping them in a low temperature environment, because they are deep-sea creatures and the pressure difference after landing can easily cause them to die. Therefore, there are relatively few real live ones.

Therefore, although there are a lot of king crabs, the difficulty and cost of catching them, as well as the small number of live ones, have together led to their high prices.

First of all, whether what is said is true or not needs to be verified.

Furthermore, the living environment required by king crabs may be different from the fishing environment.

It doesn't mean that private fishing will be allowed if there are too many fish. Many times it requires luck, opportunity, and the right time, place, and people.

There is no evidence that king crabs are rampant in Antarctica. Even if the fishing methods and capabilities have reached a certain level, if you think about the shipping costs and the dangers involved in the shipping process, you will know how expensive it is to get the crabs back from Antarctica. Therefore, it is not cost-effective.
