Ingestion rates and selectivity of the Arctic pelagic amphipod Themisto libellula were studied experimentally in Kongsfjorden (Svalbard, 78°N) during the summer period. Feeding incubations were conducted on naturally occurring copepod communities at different concentrations ranging from 25 to 250 preys L−1. The ingestion rates increased with food availability from 1.3 to 17.7 preys ind−1 day−1, which corresponded to 0.3–11% of body carbon day−1. Despite the high prey concentration used in the… CONTINUE READING
