A new technique is described to determine in situ invertebrate predation on zooplankton assemblages. The method involves staining the prey animals with fluorescent dye, acridine orange, and releasing them into a grazing chamber suspended in the lake. Predator-prey interactions can be quantified from the number of fluorescent prey and predators recovered. Predation is indicated if a suspected predator possesses a fluorescent gut tube.
