Fecal pellets of plankton play a key role in the recycling of trace contaminants within the aquatic environment. This is especially true for those plankton that undergo vertical migration in the water column. The opossum shrimp Mysis relicta is generally thought of as an omnivorous zooplankter occupying the pelagic zone of lakes, making itself available as a food source to a wide variety of fish. Several mechanisms have been suggested to explain the increase in concentration of metals from food source to fecal pellet. This study examines the feeding behavior of M. relicta to test the hypothesis that particle size selection can account for increased metal concentrations found in the fecal pellets of invertebrates.
