Four kinds of exotic crayfish breeding, etc. designated as specific alien organisms September 17 15:48
Four types of crayfish, all of which are popular as pets, have been designated as “specific alien organisms” as they could threaten ecosystems if they are thrown away in rivers and ponds, and breeding and sales have been banned in principle.
Designated as a “specific alien organism” are all crayfish of foreign species, such as “Mystery Clayfish” of the American crayfish family.
These crayfish are popular as pets, but if they are thrown away in rivers and ponds, they can threaten ecosystems, including the endangered Japanese crayfish, by catching and eating other creatures and spreading crayfish-specific diseases.
In principle, crayfish designated as specific alien organisms are prohibited from breeding, importing, or selling them from November 2nd.
People who have already bred or pet agents must apply to the Ministry of the Environment within six months for permission.
“American crayfish” is not included
On the other hand, with regard to “American crayfish”, which is particularly widely bred among crayfish of foreign species, experts said, “By specifying it, it may cause confusion, such as being thrown away in large quantities in rivers and ponds,” and it was not included in the target.
In the future, the Ministry of the Environment will consider the way regulations should be, including living creatures of other alien species that are equally widely used, such as so-called green turtles.
