This paper describes the effect of ferrite by-products on collection of abalone. Shelters used in this experiment were acryl shelters, cement concrete shelters, asphalt concrete shelters and ferrite shelters which were produced through mixing ferrite byproducts with binder. Following conclusions were obtained. 1) Ferrite shelters collected more abalones than the shelters which were made of current cement concrete and asphalt concrete. 2) Abalones kept away from acryl shelters because abalones sheltered themselves from smooth, light and semi-transparent surfaces of acryl shelter. 3) Cement concrete shelters covered with ferrite asphalt mixtures collected abalones about equal to ones which all ferrite asphalt shelters collected.
