Why did Japan introduce crayfish to our country

I only seem to know that there are Australian red shrimp? I heard that it seems to be a mutant creature? What about what about being called a biological invasion? Hehe, it's ridiculous, I don't know what that shrimp said? According to the information, foreign countries use that thing to treat sewage or something?

Summary. Because crayfish has been banned in Japan, I don't eat it<>

On May 11, 2022, the Japanese Diet voted to pass the revised Alien Biology Law, which will prohibit the release of Mississippi red-eared turtles and crayfish in the future. The revised Alien Organisms Act aims to strengthen countermeasures against alien species that may affect ecosystems.

1.Japan legislated to ban the sale of crayfish for reason 1: alien organisms.

As we all know, crayfish are also alien creatures in China, and Japan is no exception. Crayfish were first brought to Japan from the United States and proliferated in freshwater waters such as ponds throughout Japan, leading to a sharp decline in native species and sparking discussions about designating them as invasive alien species.

Why don't Japanese people eat crayfish?

Because Japan has banned the sale of Xiaolong Lupei shrimp, so I don't eat it<>

On May 11, 2022, the Japanese Diet voted to pass the revised Alien Biology Law, which will prohibit the release of Mississippi red-eared turtles and crayfish in the future. The revised Alien Organisms Act aims to strengthen countermeasures against alien species that may affect ecosystems. 1.

Japan's Nakaeda legislation bans the sale of crayfish Reason 1: Alien organisms As we all know, crayfish are also alien creatures in China, and Japan is no exception. Crayfish were first brought to Japan from the United States and proliferated in freshwater waters such as ponds throughout Japan, leading to a sharp decline in native species and sparking discussions about designating them as invasive alien species.

2.Japan legislated to ban the sale of crayfish Reason 2: Affecting the ecosystem The Japanese are not keen on eating crayfish, and crayfish were introduced to Japan as feed for bullfrog farming.

However, in Hokkaido, Japan, fishermen have caught crayfish and sent them to nearby restaurants for cooking, but it is understood that Chinese make up a large proportion of the crayfish buyers in such restaurants. 3.The reason why the sun cherry accompanies this legislation to ban the sale of crayfish is three:

Fast reproduction ability crayfish generally reproduce once a year, the number of eggs each time is generally 100-700, the average is about 300, and the incubation time of the eggs is about 14-24 days. Mating usually takes place from the beginning of May to September each year, and the peak mating period is concentrated around July and August each year. After mating is completed, the female shrimp will not lay eggs immediately, but will start spawning about 7-40 days after mating is completed.

In short, the ban on the sale of crayfish in Japan is mainly due to the impact on the ecosystem caused by alien organisms, and it has to be banned. After crayfish were brought to Japan from the United States, they multiplied in large numbers in ponds and other freshwater waters throughout Japan, causing a sharp decline in native species, so Japan intends to designate crayfish as an invasive species.

Previously, crayfish belonged to the United States, and were later introduced to China through Japan.

The species has a wide range and has been widely introduced in the United States and elsewhere from northern Mexico to Escambia County in Florida and from north to southern Illinois and Ohio, and has also been introduced to Europe, Africa, East Asia, South America, and Central America.

Introduced: Belgium, Belize, Brazil, Chile, China, Colombia, Costa Rica, Cyprus, Dominican Republic, Ecuador, Egypt, France, Georgia, Germany, Italy, Japan, Kenya, Mexico, Netherlands, Philippines, Portugal, South Africa, South Sudan, Spain, Sudan, Switzerland, Uganda, United Kingdom.

United States (Arizona, Idaho, Indiana, Oregon, Maryland, Virginia, Ohio, Hawaii, South Carolina, Utah, Arkansas, Nevada, California, North Carolina, and Alabama), Bolivarian Republic, Venezuela, and Zambia.

Habitat. Inhabit permanent streams and swamps, temporary habitats, including ditches and ponds. In streams, they are often mixed with plant or woody detritus, which can damage and weaken the embankment. In areas where the flood waters have receded, it can be found in simple caves.

Lives in wetlands, lakes and ditches with shallow water bodies and abundant aquatic weeds.

The species is found in a wide range of habitat types, including wetland meadows, subterranean karst systems, seasonal marshes and marshes, permanent lakes and streams, rice paddies, irrigation channels, and reservoirs. This species is able to tolerate a range of environmental conditions, including low oxygen levels and high temperatures.

Bullshit! I hate this rumor the most.

The main reason for this is that after crayfish were introduced to Japan from the United States, they proliferated in freshwater waters such as ponds all over Japan, leading to a large-scale decline in native species.

This organism is an omnivorous species, and its growth rate and ability to adapt to the environment are very strong, so it reproduces relatively quickly, and it is extremely damaging to the ecosystem, so we all want to get rid of it. According to the records, crayfish was introduced in Japan in 1927, 94 years ago. When it was first introduced, Japan hoped to use crayfish as feed for bullfrogs, but it did not expect crayfish to develop so strongly.

The main reasons for the introduction of crayfish in Japan are as follows:

1.Novelty and consumer demand: Crayfish is a relatively rare ingredient in Japan, and its unique appearance and taste make it a novelty that satisfies people's curiosity and needs for different tastes and ingredients.

2.Popular Preferences and Food Culture: In the last few years, crayfish has become very popular in Asian regions such as China.

As part of the food culture, crayfish is loved by many consumers because of its delicious meat and unique taste. The introduction of small rental lobsters in Japan is also to cater to the local people's pursuit of innovative cuisine and to provide more choices.

3.Nutritional value and health factors: Crayfish are rich in protein, low in fat, low in calories, and contain a variety of nutrients, such as vitamins, minerals, etc. For people who pursue a healthy diet, crayfish can be used as a low-fat, high-nutrient ingredient option.

4.Economic benefits: The rise of the crayfish market has brought economic benefits to Japan. The introduction of crayfish can drive the development of related industrial chains, including breeding, processing, catering and special products, adding new growth points to the local economy.

It is important to note that not everyone supports the introduction of crayfish. Some people are concerned that the introduction of crayfish will have adverse effects on the local ecological environment, such as competition for local species and disruption of the ecological balance. Therefore, the introduction of crayfish needs to be scientifically managed and controlled to ensure minimal negative impact on the local environment and ecology.
