In this study we have evaluated effects of various fractions of cyanobacterial biomass with different composition and microcystin content on embryolarval development of carp (Cyprinus carpio). Complex biomass and the Crude aqueous extract (regardless of microcystin content and/or microcystin variants present) in the sample were the most toxic. On the other hand, eluate tractions of all samples containing microcystins in concentrations 8-255 mu g L-1 induced no or only weak toxic effects. Exposures of fish to permeate fractions (with removed microcystins) of two samples dominated by Aphanizomenon sp. and Planktothrix sp. resulted in significant mortality, while other two samples dominated by Microcystis spp. induced minor effects. Our data indicate that cyanobacterial water blooms as well complex biomass extracts induce significant embryolarval toxicity in common carp. However, these effects were independent of microcystin content.

Embryonální testy s kaprem obecným exponovaným sincovým biomasám a jejich frakcím prokázaly největší toxicitu u celkové biomasy a vodného extraktu sinic. Toxicita byla nezávislá na obsahu microcystinů. I druhy neprodukující microcystin způsobovaly významnou embryotoxicitu.
