Clear differences in the elemental composition of the stomachs of adult Mysis relicta Lovén captured on or near the lake bottom during the day and those captured at night in the water column were observed using laser ablation - inductively coupled plasma - mass spectrometry. The elemental composition of the stomachs of mysids captured at night indicated that they were feeding on zooplankton and algae, whereas the stomachs of those captured during the day indicated sediment feeding. These results suggest that lake sediments may be a significant part of the mysid diet and that sediments transported vertically as gut contents may contribute to the transport of elements into the water column.
