Abstract
    Protozoa and invertebrates obtained from semi-enclosed eutrophic coastal waters were successfully cultured under agnotobiotic conditions. These cultures were used to investigate the influences of artificial detritus from five macrophyte species and from surface sediment on population growth as a criterion of feeding efficiency. All types of detritus tested were used as food, but differences in population growth were observed depending on the kind used. The chemical composition was correlated with the calorific value of the detritus and the possible role of microorganisms discussed. Artificial macrophyte detritus, especially that obtained from Phragmites communis leaves and Enteromorpha sp., could be very successfully used as an inert food for culturing brackish water invertebrates.
