Cohort analysis revealed a large variation in annual recruitment. It was also revealed that one cohort which had been recruited in a certain year occupied a large proportion of the whole population. Recruitment of <i>A. japonica</i> occurred from August to September whereas that of <i>A. Castanea</i> occurred from September to October. For <i>A. japonica</i>, individuals 1.5 years after recruitment seem to be mature and reproductive, and for <i>A. castanea</i>, individuals at least 1.7 years after recruitment seem to be mature and reproductive. It was estimated that <i>A. japonica</i> had a field longevity of 32–36 months and <i>A. castanea</i> could live for 55 months. Mean annual production of <i>A. japonica</i> (2.73 g AFDW·m<sup>-2</sup>·yr.<sup>-1</sup>) during two years was larger than that of <i>A. castanea</i> (0.42 g AFDW·m<sup>-2</sup>·yr.<sup>-1</sup>). Secondary production and P/B varied largely between years for both species in relation to the age of the predominant cohorts. P/B of <i>A. japonica</i> at the age of 9–20 mos. was 1.26 whereas that at the age of 21–32 mos. was 0.28. P/B of <i>A. castanea</i> at the age of 20–31 mos. was 0.64 and that at the age of 32–13 mos. was 0.32.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Life cycle and production of <i>Assiminea japonica</i> V.
