• Description: Microcystins are highly toxic peptide toxins produced in toxic cyanobacterial water blooms developing in freshwaters due to anthropogenic contamination by nutrients. In a series of studies, different freshwater fish species (common carp, silver carp, tilapia) were exposed to Microcystis spp. dominated natural cyanobacterial water bloom for up to two months, and microcystin kinetics and elimination as well as modulation of biochemical markers were studied. Toxins accumulated up to 1.4 to 29 ng/g fresh weight and 3.3 to 19 ng/g in the muscle of silver carp and common carp, respectively (determined by anti-microcystin ELISA).
