CORAL LARVA-ADHERING BASE

PROBLEM TO BE SOLVED: To provide a coral larva-adhering base which can enhance the survival rate of coral in the larva period, or the like, of the coral. SOLUTION: This coral larva-adhering base comprises a porous foamed glass body 1 which is produced by finely crushing glass cullet in an average particle diameter range of about 5 to 100μm, adding 0.5 to 5.0 wt. % of a foaming agent to the obtained fine glass particles, and then retaining the mixture at 700 to 980°C for about 25 min to sinter the mixture, and has an average pore size of about 0.5 mm. In the foamed glass body 1, the pores having various shapes and sizes, round broken pieces produced by bursting at high temperature, and the like, are irregularly formed and distributed. Thereby, various three-dimensional adhesion regions corresponding to the individually delicately different sizes, shapes, aptitudes, and the like, of the coral larvae are obtained.
