Chum prepared by use of squid liver oil is said to be quite efficient for attracting fish. The cost of the bait, which is considerable due to a large amount needed at each operation, could be reduced if fishermen were informed of the processing technique of the commercial chum or alike materials. With this view in mind the authors prepared a chumming bait on the basis of knowledge obtained from examination of the commercial products. 1) In preparation the minced meat of saury or anchovy was mixed with wet starch dregs from sweet potato on the same weight basis. Squid liver oil containing 1 percent soya lecithin was emulsified in the presence of 50 percent water. Ten percent of the emulsified oil was added to the mixed meat. 2) Experimental fishing for yellowtail was carried out in June 1959 to compare the present chum with ordinary chum in regard with fishing efficiency. The results revealed that the present chum apparently enabled the fishermen to catch a greater amount of fish at a lower cost than the ordinary chum did (Tables 1 and 2).
