The attractivity of exotic fruit flesh- or other tissue-water extracts was statistically estimated on the basis of an exploratory behavior of the abalone Haliotis discus, the oriental weatherfish Misgurnus anguillicaudatus, and the yellowtail Seriola quinqueradiata. The exotic fruits tested were 24 specimens of 19 species: 19 specimens in the flesh, 3 in the rind, and 1 each in the milk andthe albumen. The attractivity for fruit flesh was high in 6 species for abalone, 4 for oriental weatherfish, and 5 for yellowtail: kiwi fruit, grapefruit, feijoa, pepino, wax apple, and babaco for abalone; banana, kiwi fruit, babaco, and starfruit for oriental weatherfish; mango, papaya, pineapple, feijoa, and cherimoya for yellowtail. The common attractive fruit fleshes for all the three test animals were only two species, babaco and banana, though their attractivity was not so strong. The attractivity for fruit rinds was low in coconut for abalone and yellowtail, in banana for oriental weatherfish, an in grapefruit for abalone. The attractivity for coconut milk and albumen was high in the former for abalone and yellowtail and in the latter for all the three test animals. Among these fruits, the most potent attractive fruits were coconut milk for abalone, banana flesh or coconut albumen for oriental weatherfish, and feijoa fleshfor yellowtail. The attractivity of coconut milk, banana flesh, and feijoa flesh appreciably increasedwith the increase in concentration for the corresponding animals.
