Abstract:A comparison analysis of trace elements in muscle, liver and eggs of wild and cultured Paralichthys olivaceus broodstock was conducted. The results showed that contents of Se and Fe were significantly higher, while Cu was significantly lower in liver of wild fish than cultured fish (P<0.05), and no difference was found for other elements (P>0.05); Contents of both Se and Mn in dorsal muscle of wild fish were statistically higher than those of cultured fish (P<0.05), while no change was found for other elements (P>0.05); Se, Fe and Mn content in eggs of wild fish was about 1.7, 2.0 and 2.8 times higher than those of cultured fish, respectively (P<0.05). Cr content in eggs of cultured fish was 1.78 times higher than those of wild fish, however, no differences were found for Cu, Cd and Pb contents in eggs of wild and cultured P. olivaceus broodstock.
