| 内容記述 | This paper describes the diel vertical migration (DVM) of each developmental stage of a euphausiid Euphausia pacifica in Toyama Bay, southern Japan Sea, based on the samples obtained with multiple MTD nets and a PCP net on 9-11 March 1992. Eggs were laid near the surface and occasionally sank down into deep water (600m depth) before hatching. The naupliar I stage hatched out at depth, and during development probably moved up to the surface layer by Calyptopis I. Calyptopis I to III stages proved to be non-migratory, occurring in the surface layer (<100m depth) throughout the day and night. The onset of prominent DVM took place in the Furcilia II stage, linked to the morphological change of their pleopods as they adapted to swimming behavior. The amplitude of the DVM increased with developmental stage: 200m in Furcilia II to 300m in adults (including females attached with spermatophore). As a whole, however, the E. pacifica population did not perform DVM due to the predominance (57% to the total numerical abundance) of non-migratory stages (Calyptopis I to III). Surface dwelling of Calyptopis I (the first feeding stage) throughout the day might be closely associated with their feeding mode during early development and survival in the dense phytoplankton layers. | |||||
