Abstract
The feeding attractioan activities of the water-extracts of spiecs in adult oriental weatherfish Misgurnus anguillicaudatus and juvenile yellowtail Seriola quinqueradiata were statistically estimated on the basis of the time-course obtained from the fish behavior. Among thirty specimens tested in twenty-eight species of spices, allspice Pimenta officinalis and ten others for oriental weatherfish, and allspice and fourteen others for yellowtail were effective in the attraction beahvior. Above sixty per cent of the attractive specimens for both fishes were the odorus spice in characteristic. Furthermore the common attractive spices for both the fishes were the seven species of, allspice, caraway Carum carvi and cardamon Elettaria cardamomum in the odorous spice, only white pepper Piper nigrum in the acrid, and garlic Altium sativum, onion Allium cepa and savory Satureia hortensis in the odor-corrective. Especially strong attractants were caraway for oriental weatherfish, and cumin Cuminum cyminum for yellowtail. The attraction activities of caraway, cumin, and allspice clearly depended on the concentration used.
