The present studies were undertaken to elucidate the effects of color on the settlement behavior of abalone, Haliotis(Nordotis) discus REEVE. Ten young abalone, 12-20mm in shell length, were placed in the bottom of a blue cage with a single-color or a two-color plate made of methacrylate resin. The cage was suspended in an aquarium. The number of shells which settled on the plates was counted at 12 or 24 hour intervals for 5 to 10 consective days. The settlement rate of abalone in the 11 single-color plates tested varied from 0 to 94 %, and deoreasel in the following order : deep purplish red, orange, yellowish red, gray, yellow, green, black, opaque white, light purple, blue, and colorless. The difference in distribution of abalone between the two colors on the two-color plate was also tested by using 56 two-color plates, which were made by various combinations of the 14 chromatic and the 5 achromatic plates. The difference between the two colors on the 16 two-color plates was significant at the 1-percent level. The results showed that the young abalone tend to settle on the chromatic plates with maximum spectral reflectance at 550-700 nm and on the achromatic ones with low reflectance and trancemittance.
