| 摘 要： | 2005年5～11月在浙江省诸暨某池塘研究了吊养在池塘水表层下10 cm、40 cm和80 cm处三角帆蚌(Hyri-opsis cumingii)的生长。实验结果表明:吊养在不同水层的三角帆蚌成活率无显著差异,但吊养在表层下40 cm水层的蚌蚌壳长、蚌壳宽和蚌重增长速度明显高于吊养在表层下10 cm和80 cm水层的蚌,吊养在表层下10 cm处的蚌生长最慢。

| Abstract: | To examine survival and growth of freshwater pearl mussel(Hyriopsis cumingii)suspended at different water depth(10 cm,40 cm and 80 cm under water surface),a 162-day field experiment was carried out in a commercial pond in Zhuji.Results of the experiment indicated survival rate was not significantly different among the pearl mussel suspended at different water depth,however,shell length,shell width and total weight of the pearl mussel suspended at 40 cm increased faster than that of the pearl mussel suspended at 10 cm and 80 cm.The pearl mussel suspended at 10 cm had the least growth rate in shell and total weight. |
