dc.description.abstract | The phytoplankton spring bloom development and zooplankton
reproduction were investigated in April 1986 in the central and
northern Barents Sea. Different stages of phytoplankton bloom
development were found, reflecting differences in water column
stability and illumination due to ice melting. Eggs and nauplii
of Calanus, Pseudocalanus, Microcalanus and Oithona spp.
occurred mostly in the upper 50 m without any pronounced maxima
in their vertical distributions. The total numbers of eggs and
nauplii of Calanus finmarchicus and C. glacialis tended to be
higher at bloom stations than at pre-bloom stations, and also
to show a general increase during the investigation period. The
start of spawning was estimated to early February and was not
influenced by the phytoplankton bloom development. Neither did
the developmental state of the copepodite population seem to be
influenced by the bloom development. The spawning activity,
however, seemed to have a maximum coinciding with the early
phase of the bloom development. | no_NO |
