Put the cleaned spherical fertilized eggs into the breeding tank. The method is to empty the box containing the swimming spherical fertilized eggs into the breeding tank after each box has been cleaned. Four swimming, spherical eggs turn into pupae, which then develop into three species of insects that dilute the seawater salinity in the breeding tank. When the larvae develop into three species of insects, they feed on the first day of desalination. When larval holes appear in the soil, drain the water in the breeding tank, sprinkle food on the mud surface for feeding, and feed continuously for 20 days. After the nereid worms are cultivated, they are put into rice fields until they are harvested.
