[Tokyo/Chofu] 9:00 AM, 1:00 PM - *For families* American crayfish extermination event, free rental of stupid boots, free summer research with lectures on alien species

This tour aims to eradicate American crayfish, which will be designated as a conditional invasive species on June 1, 2023. This tour offers rewards based on the number of crayfish caught. Materials for summer vacation research projects are also provided. Participants spend two hours in the river catching crayfish (the total number of crayfish caught is the total number of family members). For 1 to 5 crayfish measuring 5cm or larger, participants will receive a gift of up to three sweets (a quiz must be answered correctly). For 6 to 10 crayfish, participants will receive a free dragonfly brooch (worth ¥1,000) or a ¥500 cashback. For 11 to 15 crayfish, participants will receive a net and bucket set (worth ¥2,000) or a ¥1,000 cashback. For 16 to 20 crayfish, participants will receive a net, bucket, and bubbler set (worth ¥2,500) or a ¥1,500 cashback. For 20 or more crayfish, participants will receive a free 45cm aquarium set or a ¥2,000 cashback. (Note: Crayfish received from other participants or Tosshi will not be counted.) After catching the crayfish, the tour will cover a 30-minute in-depth explanation of the ecosystem's problems, including the history of crayfish, current issues, and future responses. How about using this as a topic for your summer vacation independent study? We will also provide detailed explanations on how to raise them and teach you how to eat them. We look forward to your participation.
