Conservation and improvement of the environment is a critical ecological issue worldwide. For densely populated countries with advanced industries and intensive agriculture, maintaining a water supply of sufficient purity is vital. Effective water management is complex and requires cooperation among various authorities and research institutes. The increasing organic matter in streams and reservoirs, largely due to the widespread use of inorganic fertilizers, poses a significant challenge to water quality. This issue is global, as the demand for food necessitates more intensive agricultural practices that rely heavily on fertilizers, which contaminate water sources. Reconciling the conflicting needs of agriculture and water management is essential. Accurate data on expected organic matter levels in polluted water is crucial. A straightforward method is needed to understand the factors affecting the growth of primary producer populations, enabling assessment of their production potential. Among available methods, using algal assays to control the trophic level of natural and polluted waters shows promise. Successfully implementing this approach requires a comprehensive understanding of algal biology and physiology, as well as the selection of appropriate species and cultivation techniques. This volume summarizes current knowledge from the 1976 colloquium on algal assays in Trebon.
