It is suggested to strengthen the ecological prevention and control of invasive species such as crayfish. What impacts have these invasive species brought?

Lobster is a kind of food that many people like to eat. It tastes very delicious and is liked by many netizens. Moreover, there are many ways to make crayfish, such as braising in soy sauce, stir-frying and making hot pot. Lobster is generally more expensive. Many people think that lobster is a kind of cultured creature, but in fact it is an alien invasive species, and lobster is among the best in this list of alien invasive species.

Some alien invasive species that affect the growth of crops will be divided into different grades, and lobster is a very serious invasive grade among alien invasive species. Lobsters do a lot of harm. Most people think that lobster is a kind of food and will not have any special influence, but in fact, the vitality of lobster is very tenacious, and many lobsters grow very fast. Then they have certain adaptability to the environment and generally lurk in farmland. In this case, they may cut some crops with their claws, which is very unfavorable to the growth of crops. This invasion will definitely bring very bad effects to crops.

Competing with other species Because crayfish has super adaptability to the environment and extremely fast reproduction speed, it will slowly invade the environment where other organisms grow, especially some fresh water environments, and it must have the growth of other organisms. For example, some freshwater fish and shrimp, lobster invasion will definitely bring some harm to these species. Lobsters will have a competitive relationship with these species, and because of their strong adaptability to the environment and high survival rate, lobsters will certainly slowly invade the living environment of other species, which may reduce the survival of other species and even lead to the extinction of some species in serious cases, so this effect is very bad.

For the prevention and control of some alien invasive species, at present, our country mainly carries out manual prevention and control and some chemical prevention and control, that is to say, for the prevention and control of lobsters, chemical drugs can be used or manual prevention and control can be used, because the invasion of lobsters is more serious, and relevant departments are currently strengthening the prevention and control of lobsters.
