浮游动物粪便颗粒收集沉积物陷阱或新鲜排泄的磷虾放牧在自然浮游植物的水平在地中海的中上层在原位孵化实验室条件下，总是含有可行的海洋浮游植物，通常是硅藻。在实验室中吃单藻饲料的磷虾排泄的粪便颗粒也含有活细胞，表明某些物种的肠道通道是可行的。粪便颗粒的快速下沉似乎是将活藻类运输到深处的有效机制，并可能在海洋沃茨和沉积物中播种这种细胞。
Zooplankton fecal pellets collected from sediment traps or freshly excreted by euphausiids grazing in situ at natural phytoplankton levels in the pelagic Mediterranean were incubated under laboratory conditions and always contained viable marine phytoplankton, usually diatoms. Fecal pellets excreted by euphausiids grazing in the laboratory on unialgal diets also contained living cells, indicating viable gut passage of some species. The rapid sinking of fecal pellets appears to be an effective mechanism for transporting living algae to depth and possibly in seeding marine waters and sediments with such cells.
