Abstract: Juvenile bighead carp Aristichthys nobilis with body weight of about3 g were stocked into four alga con-trol areas including Zhushan bay,Moon bay,Three kingdoms city and Turtlemountain in Taihu Lake at a rate of 1.5 individuals/m2in June 2015,and microcystin(MCs)levels weremonthly determined in water and tissues of the bighead carp sampled from the four alga control areas from August2015 to November 2015 to evaluate the effect of MCs on aquatic edible products during the eruption period of cyanobacteria.Itwas found that the order of MCs accumulation in different tissues and organs of bighead carp was ranged from high to low as:muscle>hepatopancre-as>serum,the accumulation of MCs very significantly higher in muscle and hepatopancreas than that in serum(P< 0.01),and without significant difference amongmuscle,hepatopancreas and serum in different areas(P>0.05). In differentmonth,however,there was significant difference in MCs accumulation among muscle,hepatopancreas and serum(P<0.01).The accumulation of MCs inmuscle,hepatopancreas and serum was very significantly influ-enced by water temperature and the MCs level in the algae in water(P<0.01),body length showing very significant impacting on the accumulation ofMCs in hepatopancreas and serum(P<0.01).The higher level ofMCs in bighead carp was observed during the outbreak of cyanobacteria.According to the recommended daily intakes of MC-LR from WHO,the daily intake of 229.62-977.20 g for bighead carp in the four areas is suggested without human health risk.The findings provide reference with assessmentof accumulation ofMCs in bighead carp and food safety.
