摘　　要： 为了解企鹅珍珠贝生长规律 ,观察了壳高 2 .5～ 5.0 mm的出池幼苗 ,按月测量其生长参数和成活率 ,以及环境因子。结果表明 ,企鹅珍珠贝生长最快的月份为 7～ 11月和次年 4～ 6月 ,壳长 ,壳高和壳宽月均增加量分别为 3.8～ 13.0 mm、4 .7～ 11.2 mm、2 .3～ 3.8mm,月成活率 97.8%～ 98.6%。企鹅珍珠贝生长最慢月份是 11月至次年 From June 1999 to June 2000, the preliminary observation on growth of artificial spats of Pteria penguin which were cultured in Liusha seaport was carried out. The shell height of collected spats ranged from 2.5 to 5.0 mm, the growth parameters, the survival rate of the spats and the surrounding factors were measured monthly. The result showed that the spats of Pteria penguin grew faster from July to November and April to June the next year, the average monthly increments of the length, height and width range from 3.8 to 13.0 mm, 4.7 to 11.2 mm, 2.3 to 3.8 mm respectively, the monthly survival rate of the spats ranges from 97.8% to 98.6%. From November to March the next year, the spats grow slower.
