As tap water contains some antiseptic, they were taught to keep the water out in a container for a day or so before salmon roes are put in it; the container should be kept in a dark room until they get birth; and the water should be replaced once every three days to keep it fresh, etc. One of the school children said that "This is my sixth time to feed the salmon roes. I have learned a lot from this experience. I would like to raise the new-born fishes. I would like to ask for a help from my family." On this day, the similar lessons were given with salmon roe distribution at Murakimi Elementary School of Hanyu City, Saitama Prefecture and Otahigasi Elementary School of Gyoda City, Saitama Prefecture and Kazo Elementary School of Kazo City, Saitama Prefecture.
