在实验室实验中，混合人口的2海洋桡足类（Acartia clausi和Eurytemora longmani）喂食时，人工食品颗粒组成的微胶囊，无论是丰富的封装匀浆的天然存在的浮游植物或nonenriched优先摄取丰富的胶囊。珠粒或非强化胶囊很少摄入或根本不摄入。观察表明，这些物种的滤食是一个行为过程，在感官控制下，桡足类能够区分丰富和非丰富的食物颗粒。
In laboratory experiments, mixed populations of 2 marine copepods (Acartia clausi and Eurytemora herdmani) when fed artificial food particles consisting of microcapsules that were either enriched with an encapsulated homogenate of naturally occurring phytoplankton or nonenriched preferentially ingested the enriched capsules. Beads or nonenriched capsules were either seldom ingested or not ingested at all. The observations demonstrate that filter-feeding in these species is a behavioral process, under sensory control and that the copepods are able to discriminate between enriched and nonenriched food particles.
