| 内容記述 | The relationship between growth and population density of Japanese Spanish mackerel Scomberomorus niphonius caught in the central and western waters of the Seto Inland Sea from 1982 to 1989 was examined. Growth of this fish for each year-class was determined by investigating the mode of frequency distribution of the fork lengths of fish caught by drift gill net in spring and autumn fishing seasons. These modes were regarded as the mean fork length of one-year-old fish in autumn and two-year-old fish in spring, respectively. For the population density in both fishing seasons of each year-class, CPUE obtained from drift gill net fishery was used. As for the year-classes from 1981 to 1985, CPUE of spring fishing seasons exceeded 15-59% than that of autumn fishing seasons. This situation changed, however, in 1986 and 1987 year-classes though the cause was not clear. As for the year-classes from 1981 to 1985, in both autumn and spring fishing seasons, negative correlations between CPUE and fork length were observed (autumn; r =- 0.783, spring; r =- 0.824). | |||||
