Abstract
This paper describes effects of color on abalones gathering to the shelters. The experiments were carried out in the laboratory by using abalones and colored shelters. Following conclusions were obtained. 1) The color attributes of the dry shelter surface were similar to those of the wet shelter surface. 2) Gathering rates of abalone to the shelter were similar, if the color attributes were the same. 3) The lower lightness of shelter surface, the more abalones were drawn into the shelters. 4) The lower saturation of shelter surface, the more abalones were drawn into the shelters.
