Abstract

Analyses of monthly depth-stratified (0–2000 m) sampling data in the Oyashio region have revealed that <i>Aglantha digitale</i> is distributed largely in the upper 250 m throughout the year. Population biomass ranged from <30 mg DW m<sup>−2</sup> (January) to 1575 mg DW m<sup>−2</sup> (August), with an annual mean of 186 mg DW m<sup>−2</sup>. Judging from seasonal sequences of the population structure, the generation length of <i>A. digitale</i> is considered to be one year with their spawning season in June-September, which is consistent with that observed at Station P in the eastern subarctic Pacific.
