- Аннотация: We analysed the pattern of spatiotemporal distribution of harpacticoid assemblages of 106 plankton samples collected in May–August of 2013–2015 in Prostor Bay, South Kuril Islands (Sea of Okhotsk). Taxonomically and ecologically diverse harpacticoid assemblages were found in the water column. Among the 49 species identified, only one was truly planktonic, while the others were typically benthic, mainly phytal-dwelling forms. The most abundant and rich (42 species) assemblage occupied the shallow (10 m depth) area in the western, stone-bottomed part of the bay with a well-developed phytal zone. In deeper areas, theabundance and diversity of harpacticoids in plankton samples decreased steeply. There was a clear seasonal pattern of abundance, diversity and composition, with a peak in spring and thena decrease. On average, the total abundance was low (64 ind/m2). Neither interannual variations contributed significantly to the harpacticoid distribution. The analysis of the gut contents suggests that the harpacticoids feed on planktonic diatoms in the water column, but their residence time in the water column was short, and their feeding rate was low. In turn, the harpacticoidsconstituted a permanent but relatively minor fraction of the salmon fry diet. Thus, in quantitative terms, harpacticoids contributerelatively little to benthopelagic coupling in the Prostor Bay ecosystem.
