Annotation	Fish embryos and larvae are frequently subject to chronic and damaging exposure of cyanotoxins released by live and decomposing cyanobacteria. Whereas the majority of former studies dealt with the embryotoxicological effects of pure toxins and extracts, we focused on the evaluation of toxic effects of crude cyanobacterial biomass. Samples of crude cyanobacterial biomass - intended for embryotoxicological tests with eggs of Japanese medaka, Oryzias latipes (strain Q2d-rR.YHNI) - were collected from natural bodies of water in the Czech Republic. In the preliminary optimization experiments, various numbers of fertilized medaka eggs were hatched under standard conditions. Cyanotoxicity significantly affected all examined parameters in medaka embryos. The study proved significant embryotoxic effects upon Japanese medaka at environmentally relevant levels of cyanobacteria commonly occurring in surface waters in Europe.
