What a headache is biological invasion? Fiercer than asian carp: Asian tiger shrimp as big as an arm, the Americans have nothing to do...
Asian tiger shrimp, also known as black tiger shrimp, is named because of its black-brown appearance, which has the characteristics of fast growth, large size and strong ability to adapt to the environment.
These features allow Asian tiger shrimp to survive in many seas and grow to the size of a human arm.
Such Asian tiger shrimp have caused a lot of trouble for the United States.
Due to its strong adaptability, The Asian tiger shrimp entered the US basin without hindrance, and once it came, it "occupied the mountain as king" and launched an attack on the shrimp in the basin.
Because it is too "can fight", there are almost no opponents in the native shrimp.
As a result, the reserve grain of Asian tiger shrimp is getting more and more, and the size is naturally getting bigger and bigger.
Some people may wonder why the United States does not fish and sell such Asian tiger shrimp as a natural table delicacy.
The reason is actually very simple, that is, Asian tiger shrimp have been seriously polluted in some parts of their lives, which has led to their toxicity.
That is to say, when people see a black tiger shrimp, they don't even know whether it is poisonous or not, whether it can be eaten, naturally no one dares to risk eating it.
Since it is impossible to eat, there is only one way left, and that is to salvage it.
When it comes to the topic of salvage of biological invasions, it is a cliché for the United States, because just before the Asian tiger shrimp, the United States also experienced a biological invasion, that is, the Asian carp.
The crazy growth of Asian carp is inseparable from the initiative of the United States.
This is a creature introduced by the United States in order to control aquatic weeds and algae, but it did not expect that after entering the United States, it would breed rapidly in a short period of time because there were no natural enemies.
Due to the vitality of Asian carp, native fish are not its opponents at all, so in the places where Asian carp is infested, native fish have basically become their "prey".
In order to control this biological invasion, the United States has thought of many ways, and even approved more than 70 million special funds to control it.
However, whether it is artificial fishing or spraying drugs into the river, the effect can be said to be minimal.
Wave after wave of unevenness rises again.
Asian carp has not yet been solved, and Asian tiger shrimp has become another headache for the United States.
The United States realized that this biological invasion had caused huge economic losses, so it finally started from the legislative level, hoping to prevent the invasion of alien organisms through legal restrictions.
Unfortunately, exotic creatures such as the Asian tigerfish are not controlled by U.S. law and continue to thrive on the East Coast of the United States.
The United States can only watch it breed and be helpless, and cannot find any effective measures to "confront" it.
