50 million king crabs flooded and even threatened the Antarctic ecology? Is eating king crab saving the planet? What the hell is going on here?
The alias of the king crab is Alaskan king crab, originally lived in the Alaska region of the United States, a Soviet biologist in the last century thought, the Soviet Union is also a large aquatic consuming country, importing king crab every year, to the old United States to send silver is not a blood loss, if you get domestic breeding, can not spend less money?
So in 1960, he successively transported 3,000 king crabs back to China and put them in the Barents Sea for breeding. Perhaps it is negligence, there are crabs escaping during breeding, whether it is deliberately released, let's not say. This king crab is able to spawn thousands of eggs at a time, and after a few decades, the entire sea is covered by 50 million crab troops, but this brings us to an interesting place, connecting the north corner of northern Norway with Bear Island, which is a dividing line, on the left is the Norwegian Sea managed by Norway, and on the right is the Barents Sea managed by Russia
Originally the king crab flooded in the Barents Sea, who wanted to quietly run to the Norwegian Sea, Russia was very happy, arranged fishermen to go to the sea to fish, but Norway is not good at this mouth, see the king crab on the head, so there is such a scene.
If you catch king crabs in the Barents Sea east of the demarcation line, you must release them, and if you do not do well, you will be fined a squat, and if you catch a king crab in the Norwegian Sea west of the demarcation line, you must not release them, and if you do not do well, you must also be fined a squat, and the same king crab has a different fate.
Alaskan king crab is huge, the largest can grow to more than 10 kilograms, counting the length of the leg must be 80 cm, in the hometown of Alaska, many creatures compete with it, but in the Barents Sea, there are no ferocious creatures to compete, the life of the king crab is still passable, carefree reproduction, as an invasive species, it lives up to expectations, spreading from the Barents Sea to the Norwegian Sea, and even migrating westward.
King crab is an omnivore, fish, shrimp, aquatic grass sea urchin humus, can enter one do not let go, due to the huge number, although the place can not be said to be grass is not raw, but at least it is eaten clean, accelerated the desertification of the ocean, so Norway has issued a regulation, catch the king crab who dares to release, let who goes to jail. And the fishermen want to fish, who want to go down a net is all king crabs, the net line can be cut, which makes them sad.
Barents Sea 50 million king crab flood, on this government also restrict fishing, only the fishermen who issued a "crab hunting license", can catch a certain quota of crabs, but due to bad weather, a trip to the sea risk is extremely high, the whole people and ships are empty, of course, the income is also quite high, it is said that making millions in one or two days is not a problem
Then again, king crabs like to live in 2-5 degrees Celsius waters, originally would not have expanded to the polar region, who wanted to 2004, there were scientists in the Antarctic discovered the king crab, how it got here I don't know, but what I do know is that there are no large predators in the Antarctic sea, many creatures are rookies
The sea urchins in other places are full of spikes, and there is still a little defense against crabs, and the Antarctic sea urchins are exposed, and they can eat it without tongs, which leads to the king crab coming to an unmanaged cafeteria, what to eat, what to take, if it appears on a large scale, it will destroy the Antarctic ecology, so every king crab you eat is saving the earth
However, the price of saving the planet is a bit expensive. In fact, once the species is invaded, it will be difficult to completely eradicate, such as tilapia, scavengers, a yellow flower, crayfish, all of which make us big enough, and how to completely solve the king crab that invaded Antarctica is really a problem.
