Abstract

The food spectrum of nine water mite species was investigated by the ¹⁴C method, and it was found: 1. None of the nine species consumed plants or detritus, and only five species fed on cladocerans. 2. Among the species feeding on cladocerans a high degree of food selectivity was observed. Of the five crustacean species offered as food the Daphnia longis'pina and Bosmina longirostris were preferred most. No species consumed Sida crystallina at a high rate. 3. Feeding Piona coccinea on Ceriodaphnia quadrangula the optimum food concentration was 40-50 mg biomass/litre.
