摘要
在桑沟湾内，对栉孔扇贝Ｃｈｌａｍｙｓ（Ａｚｕｍａｐｅｃｔｅｎ）ｆａｒｒｅｒｉ（ＪｏｎｅｓｅｔＰｒｅｓｔｏｎ）的笼养与串耳养殖等不同养殖方式及不同水层（１ｍ、２ｍ、３ｍ、４ｍ）的养殖效果进行了综合试验和分析。结果表明：（１）串耳养殖的扇贝平均壳高增长比笼养扇贝生长快，两种方式效果差异极明显（Ｐ＜０．０１）；（２）串耳养殖方式以２ｍ为最佳养殖水层，其次为１ｍ和３ｍ，４ｍ水层最差，而且２ｍ与４ｍ的养殖效果存在明显差异（Ｐ＜０．０５）；（３）笼养方式的最佳水层为４ｍ，其养殖效果依次为４ｍ＞１ｍ＞３ｍ和２ｍ。试验显示，在不同的养殖方式下，栉孔扇贝最佳生长的养殖水层是不同的。
The influences of culture methods (ear-hanging culture and lantern net culture) and water depth (1m, 2m, 3m and 4m under water surface) on growth of scallop Chlamys (Azumapecten) farreri (Jones et Preston) were studied during May 1994 and December 1994 in Sanggou bay. Results show that: (1) Scallops cultivted by ear-hanging method grow faster than those cultivated by lantern net metholl do, and the difference is very significant (P<0.01). (2) Cultivated by ear-hanging method, the orders of growth rate (from high to low) of scallop cultivated in different depths is: 2m>1m and 3m>4m. (3) Cultivated by lantern net method, on the contrary, the orders of growth rate is:4m>1m>2m and 3m. This indicated that the optimal culturing depth varied with culture methods, the optimal culture depths are 2m in ear-hanging method and 4m in lantern net culture method, respectively.
