    ABSTRACT: Loop-shaped trajectories are commonly observed in the stock recruitment relationship (SRR). A mechanism has been proposed that explains why the loops emerge in SRR. The aim of this study is to validate the mechanism using data for the stocks of 24 fish species that live in the waters around Japan. The following three questions are examined: 1) whether or not loop shapes are detected in SRRs for all 24 stocks; 2) whether or not the direction of the loops, i.e., clockwise or anticlockwise, changes depending on the age at maturity; and 3) whether or not the slope of the regression line adapted for SRR changes depending on the age at maturity. The results were as follows: 1) loop shapes in SRR were recognized for all 24 stocks analyzed in this study; 2) clockwise loops were dominant when the age at maturity was low, and anticlockwise loops were dominant when the age at maturity was high; 3) the slope of the regression line adapted for SRR has a negative relationship to the age at maturity. When the age at maturity was low, the slope was positive but less than unity. When the age at maturity was high, the slope had no trend and was recognized as statistically zero. These findings will drastically change the concept of SRR. All previous findings obtained by analyzing the SRR may be better to revise essentially.
