To clarify the factors influencing variation in gut content characteristics of Scomber japonicus larvae collected in the daytime off Sendai City, Kagoshima Pref., Quantification I analysis was made with 4 main food organisms (Appendicularia, Crustacean eggs, Evadne, and Oithona), weight of gut contents, and feeding incidence as the outside variables, and total length, sampling hours, and sampling stations as the items. The result showed that the variations of weight of gut contents, Appendicularia, and Oithona were influenced the most by total length, and those of the other 3 by sampling stations among the 3 items. However, the partial and multiple correlation coefficients between the outside variables and items were very low, except for feeding incidence. The composition of gut contents of spotted mackerel Scomber australasicus larvae is given in the Appendix Table.
