摘要
本文研究了纹藤壶在海湾扇贝（Ａｒｇｏｐｅｃｔｅｎｉｒｒａｄｉａｎｓ）、试板和虾塘设施上的定向，结果表明：纹藤壶在海湾扇贝上主要附着于壳的顶部（７５．００％）和耳部（２０．９７％），且以多个体附着为主；纹藤壶在海湾扇贝上以０°方式定向，有四种定向类型，定向角度分别为：１５１．１０°、－１５７．４２°、３８．８８°、－３７．９６°；纹藤壶幼体附着于扇贝的肋间沟中，具有向皱性。纹藤壶在试板上迎水流定向，定向角度为：１２．６８°、－１７．２４°。纹藤壶在竹桩上送光定向，定向角度为：１６８．６９°、－１５９．９５°．
The sessile situations of Balanus amphitrite amphitrite on Aropecten irradians are top (75. 00%) and 'ears' (20. 97 %). The amount of B. amphitrite amphitrite is mainly more than one on each A. irradians. B. amphitrite amphitrite orientates on A. irradians in direction of 00 state. But there are four types of orientations. The angles of orietations are; 151. 100, - 157. 420, 38. 880, -37. 960. The larvas of B. amphitrite amphitrite settle in the sunken of the shell of A. irradians. The orientation of B. amphitrite amphitrite on board depends on the current. The angles are : 12. 680. - 17. 240. The orientation on bamboo depends on the light. The angles are : 168. 690. -- 159. 950.
