抄録

An index for the attractive effect of food was sought from three behavioral responses of active juvenile yellowtail, which entered, left and remained in the test compartment containing food. The attractive effect based on the main locmotive activity as observale attractive criteia could be represented as the product of the coefficients g and r of a logistic curve, y=g/{1+exp[-r(j-a)]} in the entering or the leaving time-course.<br> The attractive effect of various kinds of food, either the whole or the tissue of the organisms macerated, was examined by using the method mentioned above. Among seven classes of seawater organisms tested as food, polychaets, cephalopods, crustaceans and teleosts were found to be effective attractants. Blood worm Marphysa sanguinea, squid Lolig edulis edulis, whiskered velvet shrimp Metapenaeopsis barbata and flying fish Prognichtys agoo were the food that provoked remarkable exploratory and feeding behavior. Among three classes of forshwater organisms, strong attractants were only two kinds of crustaceans, sawtooth caridina Caridina denticulata and lake prawn Palaemon paucidens. None of the terrestrial organisms examined were effective.
