Combined with the full text analysis, why do experts suggest that the best way is to eat those Asian carp?

Asian carp refers to carp native to Asia, which is the American name for herring, grass carp, bighead carp, carp and silver carp.

The United States imported these fish from China in 1970s to improve the ecology. However, with the increase of the population, Asian carp have propagated to the Great Lakes of the United States, endangering the local ecological environment. In order to protect the local ecology, the American government began to kill Asian carp on a large scale at the end of 2009. 20 14, 18 10, the Obama administration announced that it would spend1800 million dollars to prevent the Great Lakes from being invaded by Asian carp for 25 years. From September 9, 20 14 to June 2, 20 14, JimGarvey, an American Asian carp expert, and his companions organized a delegation to China to find a solution to the flooding of Asian carp in the United States.

Introduce silver carp

In the 1960s, the United States was eager to find a safer way to control the proliferation of aquatic plants and algae than chemical drugs. As a result, the US Fish and Wildlife Service came up with the "biological method". In 1970s, in order to clean up harmful algae in fresh water, Americans introduced silver carp from China and other Asian countries to Arkansas. Subsequently, many fish farms followed suit and regarded silver carp as an excellent natural pond cleaner. [3]

flood

After the 1980s, Asian carp escaped from the limited waters and entered the Mississippi and Illinois rivers, where they proliferated, causing devastating disasters to rivers and lakes in more than ten states in the United States. This kind of fish is huge, eats everything and has no natural enemies. The US Department of Agriculture has spent more than $654.38+08 billion trying to prevent Asian carp from further invading the Great Lakes, but the prospect is not optimistic. Americans don't like to eat freshwater fish, and they don't know how to cook Asian carp and how to get rid of the earthy smell. They can only watch Asian carp run wild and do nothing. [3]

In the 1990s, due to several floods in the Mississippi River, these fish went north along the Mississippi River. Other "Asian carp brothers" (even goldfish and koi fish) have also become "illegal immigrants". Due to the lack of natural enemies, these fast-growing and high-yielding "carp" have become local water tyrants. [4]

massacre

At the end of 2009, in order to eliminate Asian carp, researchers and environmentalists in Illinois, USA, began to put a lot of "fish-killing drugs" into rivers near Lake Michigan (full length 10 km), thus maintaining the "ecological balance" of water bodies and preventing this exotic species from entering the Great Lakes. However, as of June+February, 5438, the authorities only found one Asian carp with a body length of less than 60 cm from the poisoned fish species, and all other poisoned fish were "American citizens".

Because ordinary Americans don't like to eat carp with too many thorns, there seems to be no better way to kill them than "mass slaughter". But Asian carp are smart, know how to avoid fishing nets, and will not be easily hooked. Some Americans say that Asian carp is actually delicious, and if it can be made into delicious and stingless fish products, it may help mankind to "destroy" this freshwater creature more quickly. [5]

In some rivers in the United States, the number of Asian carp has accounted for 90% of the total number of fish. At least three species of Asian carp have been found in the waters of the Great Lakes, two of which are in American waters and one in Canadian waters. Although the U.S. government has set up a defense power grid in the rivers leading to the Great Lakes, it seems that it has failed to effectively prevent carp from going north.

Hunting was attacked.

20 10 in April, a woman was attacked by Asian carp while hunting in the Illinois River. A carp suddenly jumped out of the water and slapped the woman. [4]

Asian carp is a famous invasive species in the United States, which has invaded the Great Lakes of North America. This caused great panic among the American people, and the issue of Asian carp even entered the agenda of the White House. The White House specially held the "Asian Carp Summit".

Silver carp attacked the hunter.

Because the American people think that Asian carp will destroy the ecological balance, the movement of hunting Asian carp has arisen. Many people hunt the flooded Asian carp with bows and arrows. The woman who was attacked was no exception. She is preparing to catch Asian carp with a bow and arrow. But a brave Asian carp attacked her. The woman was caught off guard and was slapped heavily by Asian carp, causing her injury.

Chris Brackert specially organized a sport called "Shooting Fish in the Extreme Air", providing participants with bows and arrows and shooting Asian carp by speedboat. Although the sport is becoming more and more popular, it is full of dangers, not only for Asian carp, but also for hunters. It was Chris Brackett's fiancee Barnes who was suddenly attacked by Asian carp. [6]

Prevention plan

20 12 In February, the Obama administration announced that it would spend 510.5 million dollars in 20 12 to prevent the Great Lakes from being invaded by Asian carp. In the Mississippi River, Asian carp frantically snatch food from the mouths of local fish and are now called "the most dangerous alien species" by American officials. Tim Elda, executive director of the Great Lakes Committee of the United States, said that the invasion of Asian carp has been difficult to be completely controlled, and the best hope is not to spread to more rivers.

Together with the budget of 20 12, the federal government of the United States has invested a total of 654.38+565 billion dollars in three years to resist the invasion of Asian carp. Asian carp can be found in most parts of the Mississippi River. There are four kinds of Asian carp that are worrying. They are bighead carp, silver carp, herring and grass carp, and they are huge. In North America, no other fish is big enough to eat an adult Asian carp. White pelicans and eagles can only eat young or younger adult Asian carp. Asian carp is extremely fertile and grows very fast. They grab a lot of food from local fish.

In 20 12, the measures that the U.S. government intends to take include trapping carp with peculiar smell, scaring them with acoustic water guns, collecting water samples on a large scale for the first time and strengthening the layout of fishing nets. Scientists collected dozens of water samples containing Asian carp DNA in the waters near Chicago.

In 20 12, the U.S. government plans to increase the number of samples, and collect water samples in waters including South Lake Michigan, West Lake Erie, Detroit River, Saginaw Bay of Lake Huron, and Green Bay of Lake Michigan. To confirm whether this destructive fish has "camped" in the Great Lakes. [7]

On June 5th, 20 13, a China company named "Liangjiang Fishery Company" plans to invest 2.5 million US dollars to set up a factory in Kentucky, USA, to process Asian carp, buy carp from American fishermen, and transport them to the Asian market for human consumption after processing, and also as raw materials for producing feed and fertilizer. After the factory is completed, it will handle 6,543,800+carp caught by American fishermen from the river every day. [8]

The United States spent $654.38+0.8 billion to ban Asian carp for 25 years.

2014 65438+1October 18 According to foreign media reports, Asian carp invaded the United States and propagated wildly, and the aquatic life of the Mississippi River has collapsed. In order to prevent them from entering the Great Lakes from the Mississippi River, the U.S. government decided to spend/kloc-0.8 billion yuan in 25 years to build dams to stop Asian carp. However, experts worry that the five lakes will be occupied before the dam is completed. [9]

The Battle of "Asian Carp" The United States came to China to "move reinforcements"

From September 9, 20 14 to June 2, 20 14, JimGarvey, an American Asian carp expert, and his companions organized a delegation to China to find a solution to the flooding of Asian carp in the United States. [ 10]

Strengthening research cooperation between the United States, China and other countries can create more opportunities for economic cooperation and promote more demand for Asian carp. Next, the China delegation will visit Southern Illinois University. It is hoped that the exchange of experience between China and the United States will help the United States to effectively control Asian carp, and at the same time, it will also help China Yangtze carp to breed.

Besides, Americans don't like to eat this kind of fish. They usually eat sea fish, so they suggest eating it.
