“…The most important planktivorous fish are H. molitrix and A. nobilis, whereas C. auratus and C. carpio are important omnivorous fish. These fish are all native to Lake Taihu and economically important for human consumption (Peng et al, 2010;Zhang et al, 2009). The harvest of H. molitrix, A. nobilis, C. auratus and C. carpio comprised nearly13% of the total fish harvest.…”

Microcystins (MCs) are the toxic products of harmful algal blooms and they accumulate in fish. The accumulation of MCs in fish living in different trophic levels from different parts of Lake Taihu was determined. This information was then used to evaluate the risks posed by the MCs in fish to human health. The concentrations of three MCs, MC-LR, MC-YR and MC-RR, were quantified in the following four fish species: silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis), crucian carp (Carassius auratus) and common carp (Cyprinus carpio), using high performance liquid chromatography interfaced with tandem (triple quadrupole) mass spectrometry. The mean concentrations of MCs in the muscle, the kidney, the intestinal wall and the heart were significantly different among the four fishes except in the liver. C. carpio contained the highest mean concentration of MCs in the muscle (31.7 ± 12.1 ng/g, dry mass (dm)), whereas C. auratus had the highest mean concentrations of MCs in the liver (45.4 ± 44.5 ng/g, dm), kidney (114 ± 51.1 ng/g, dm), intestinal wall (2.04 × 10 3 ± 4.43 × 10 3 ng/g, dm) and heart (59.5 ± 26.7 ng/g, dm). The mean concentration of MCs in the intestinal walls of the fish species was significantly higher than in other organs (p b 0.01). The fish from Meiliang Bay had significantly higher concentrations of MCs than those from the centre, west or south banks of the lake (p b 0.01). The body lengths and masses of the fish were negatively correlated with the concentrations of MCs in the kidney (p b 0.05) and heart (p b 0.01). The average daily intake (ADI) of MCs in the muscle of all fishes exceeded the provisional tolerable daily intake (TDI) set by World Health Organization. The estimated daily intakes of MCs in 55.6% of the muscle samples exceeded the TDI. The MCs in the tissues of the fish from Lake Taihu pose potential risks to the health of humans who consume these four fish species.

“…Both H. molitrix and A. nobilis are also exported to other countries and comprise up to 18% of the total freshwater fish production in the world (Xie et al, 2004;Xie and Liu, 2001). Therefore, all of these fish discussed above are economically important (Peng et al, 2010;Zhang et al, 2009). …”

“…Previous studies showed the average concentration of dissolved MCs in Lake Taihu and Lake Los Padres (Argentina) were 2.52 and 1.71 mg/L, respectively (Peng et al, 2010;Valeria et al, 2010). As Lake Dianchi is located in the Yunnan-Guizhou Plateau of China, strong UV irradiation may lead to lower concentrations of dissolved MCs in this lake (Sakai et al, 2007;Peng et al, 2010).…”

“…As Lake Dianchi is located in the Yunnan-Guizhou Plateau of China, strong UV irradiation may lead to lower concentrations of dissolved MCs in this lake (Sakai et al, 2007;Peng et al, 2010). On the other hand, the concentrations of total MCs in Lake Dianchi were much higher than in Lake Los Padres (0.16e15.77 mg/L) (Valeria et al, 2010), due to the higher cyanobacterial biomass in the former.…”
