クローン危険外来生物まだいる！愛媛県松山市！みんなで拡散防止！マダラザリガニ Marbled crayfish, Procambarus virginalis ≫生物ハンター加藤英明【公式】かとチャン

Let's all search! Let's go foraging! The dangerous invasive species, the Spotted Crayfish! (Mystery Crayfish) The invasive Spotted Crayfish has established itself in Matsuyama City, Ehime Prefecture! There are still many more. Prevent further spread! We ask for everyone in the community to take countermeasures. They become a nuisance if they enter the Shigenobu River… Of course, large catfish that like crayfish will eat them, but the Spotted Crayfish is something to watch out for. The Spotted Crayfish breeds in May. Females carry hundreds of eggs and hide without eating. They also breed in the fall! Let's actively remove them before breeding. All Spotted Crayfish are female! They reproduce individually. They are all clones… Please be considerate of the creatures when exploring. Release native species after observation! Don't take home medaka or newts; let's all enjoy observing them together. *Specified invasive alien species cannot be moved alive. Survey conducted March 8, 2026 [YouTube] Dangerous cloned invasive species are still around! Matsuyama City, Ehime Prefecture! Let's all work together to prevent their spread!
