摘要: The levels of mineral element Na, Mg, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Mo, Al, As, Ag, Cd, and Tl were quantified in the whole shells of the freshwater bivalve Anodonta woodiana at three different growth stages (i.e. J1 juveniles of 1month old, J2 juveniles of 3.5months old, and adults of 36months old). The concentrations of Na and Al were different between different growth stages (p<0.05). The highest Na concentrations (2715 +/- 86g/g dry weight) were found in J2 juveniles. The highest Al concentrations (303.9 +/- 5.95g/g dry weight) were found in J1 juveniles. Manganese concentrations (517.0 +/- 47.98g/g dry weight) were significantly higher in J2 juveniles than in J1 juveniles (432.3 +/- 9.87g/g dry weight) (p<0.05). Copper concentrations (27.32 +/- 0.15g/g dry weight) were significantly higher in J1 juveniles than in J2 juveniles (26.21 +/- 0.86g/g dry weight) and adults (24.74 +/- 1.43g/g dry weight) (p<0.05). Burdens of Na, Ca, Mn, Fe, Co, Cu, Mo, Ag, and Tl were positively correlated with the shell length (p<0.05). These findings can possibly contribute to an understanding of elemental requirements for shell growth and, hence, facilitate improvement of survival and growth rates during artificial mussel culture.
