摘要

Analyses of monthly depth-stratified (0–2000 m) sampling data in the Oyashio region have revealed that Aglantha digitale is distributed largely in the upper 250 m throughout the year. Population biomass ranged from <30 mg DW m⁻² (January) to 1575 mg DW m⁻² (August), with an annual mean of 186 mg DW m⁻². Judging from seasonal sequences of the population structure, the generation length of A. digitale 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.

每月的深度分层的亲潮区（0-2000米）的采样数据的分析人士透露，Aglantha DIGITALE主要是全年分布在上250米。从30毫克DW米种群生物量介于SUP -2 / SUP（日）至1575毫克DW米SUP -2 / SUP（月），有186毫克DW米的年平均SUP -2 / SUP。从人口结构的季节性序列来看，A DIGITALE的世代长度被认为是一年，他们的产卵季节在6-9月，也就是与在站P东部亚北极地区观察到的是一致的。
