Abundance and biomass of copepods and cladocerans in Atlantic and Arctic domains of the Barents Sea ecosystem.

ABSTRACT: Zooplankton in the Barents Sea have been monitored annually with a standard procedure with determination of size-fractioned biomass since the mid-1980s. Biomass of copepods and cladocerans was estimated based on measured abundance and individual weights taken from literature. Calanus species were dominant, making up ~85% of the estimated biomass of copepods. The second most important taxon was Oithona spp. (~0.5 g dry weight (dw) m^-2, ~10%), followed by Metridia spp. (~0.15 g dw m^-2, 2-3%) and Pseudocalanus spp. (0.10-0.15 g dw m^-2, 1-5%). Estimated biomass of cladoceran taxa (Evadne and Podon) was low (0.01 g dw m^-2). Calanus spp. contributed most of the biomass of the medium size fraction (1-2 mm
