摘要: Sthenoteuthis oualaniensis is a species of cephalopod that is becoming economically important in the South China Sea.Zn,Cu,Cd,Cr,As,Hg and Pb concentrations were determined in the mantle,ann and digestive gland ofS.oualaniensis from 31 oceanographic survey stations in the central and southern South China Sea.Intraspecific and interspecific comparisons with previous studies were made.Results showed that concentrations of Zn,Cu,Cd,Cr,As and Hg in mantle,arm and digestive gland of S.Oualaniensis captured in the central and southern South China Sea showed no significant differences (P < 0.05) with mantle length and seasons.Mean concentrations of trace elements analyzed in arms and mantle were in the following orders: Zn > Cu > Cd > Cr > As > Hg.In digestive gland,the concentration of Cu and Cd exceed that of Zn.All the Pb concentrations were under the detected limit.
