Abstract
Attraction activities of terrestrial vegetables for black abalone Haliotis discus, oriental weatherfish Misgurnus anguillicaudatus, and yellowtail Seriola quinqueradiata were estimated by behavioral experiments in a laboratory test tank aswell as an attraction index a for both abalone and oriental weatherfish, and another attraction index gr for yellowtail. The indexes a and gr were estimated by a method described in previous papers. Most of the vegetables tested (39 breeds from 36 kinds of vegetables) showed, to some extent, attraction activities for these three animals tested. The highest activity was observed in soybean Glycine max for black abalone, cabbage Brassica oleracea var. capitata (Nakawase 2) for weatherfish, and onion Allium cepa for yellowtail. The attraction activities of these vegetables clearly depended on the concentrations used.
