| 摘 要： | 研究蟹板茗荷在三疣梭子蟹鳃及口肢上的定向、附着和种群特征 ,结果显示蟹板茗荷主要附着在三疣梭子蟹鳃的腹面 ,占 67.86% ,以在第五对鳃上的附着量最大。位于鳃腹面的蟹板茗荷主要以 0°方式定向 ,鳃背面的蟹板茗荷则主要以± 90°方式定向 ,鳃室壁上的蟹板茗荷主要以 0°方式定向。蟹板茗荷在不同的附着部位形态上有差异 ,口肢上的个体柄短、壳板厚而硬 ,鳃室里的柄长、壳板薄而软。附着于三疣梭子蟹鳃及口肢上的蟹板茗荷 ,其种群年龄结构和数量组成有明显的季节变化。

| Abstract: | Octolasmis is a special Genus in Cirripede. Octolasmis spp. attached on the gills and appendages of crab. They have formed the special biological characteristics for adapting the sessile life during the long term evolutionary process, effecting the breath, development and ingestion of hosts. Goose barnacle, O. neptuni attached on the gills and appendages of the swimming crab, Portunus trituberculatus, one of the important crab in China, effecting the growth and development of the hosts. We stu... |
