AbstractDaily intake and accumulation of microcystins (MCYSTs, MCs) in silver carp (Hypophthalmichthys molitrix) were investigated under lab conditions by feeding the fish exclusively with fresh toxic Microcystis bloom at a density of 6 x 10(9) algal cells L-1. The medial lethal dose (LD50) of microcystin-LR to silver carp was estimated to be 270 mu g kg(-1) body-weight, underlining its strong resistance to toxic Microcystis bloom. It can survive after being ingested with high doses of microcystins (about 10 mg kg(-1)) during the 28-days feeding experiment. Enzyme-linked immuno-sorbent assay results show that microcystin concentrations in muscle and liver are 1.57 +/- 0.31 mu g kg(-1) and 4.28 +/- 1.64 mg kg(-1) fresh weight. The former is much lower than the World Health Organization limit recommended for human consumption. These results suggest that silver carps can be widely used in cyanobacterial bloom control, and consumption of fish muscles is safe for human beings.; Daily intake and accumulation of microcystins (MCYSTs, MCs) in silver carp (Hypophthalmichthys molitrix) were investigated under lab conditions by feeding the fish exclusively with fresh toxic Microcystis bloom at a density of 6 x 10(9) algal cells L-1.
