Description of the Related Art For example, when a shallow-sea bivalve such as a clam is propagated in fish, a release study is conducted to observe the growth rate of seedlings (fry) over time. This release survey is to release specific marked juveniles as labeled shells and observe the growth rate after that.As a method of marking juveniles, conventionally, for example, on the surface of the shells of labeled shells. Paints such as paint were applied with a brush or spray, and a cutting tool such as a diamond pen with high hardness was used to scrape off a part of the shell surface to scratch it.

おそれもある。The method of applying the paint to the shell surface is such that the shell surface rubs against the sand and the coating film is easily peeled off because the bivalve shell has the property of diving into the sand. The scratching method not only takes time technically, but also requires skill to surely cut, and further damages the shell body, so that the shell cannot be regenerated.

The color does not peel off even after a lapse of time or when the shell surface rubs against sand. Further, since it is chemically colored, it is possible to easily work without requiring skill. Further, even if the juvenile shell grows, the colored portion does not become large accordingly, so that the growth degree can be measured easily and surely.
