福建沿海文昌鱼的分布

Distribution of Amphioxus in the Fujian Offshore Waters

本文根据在福建沿海收集的文昌鱼资料,经鉴定有两种文昌鱼,即厦门文昌鱼和短刀偏文昌鱼。简要描述了文昌鱼的数量分布和一些生态特征。厦门黄厝海区的厦门文昌鱼栖息密度最大,一些文昌鱼新的分布区密度低,没有经济意义。

The paper is based upon amphioxus samples collected in the Fujian offshore waters. Two species of amphioxus (Branchiostoma belcheri (Gray)) and Asymmetron cultel lum (Peters)) are identified. The quantitative distributions and other ecological characters tics of amphioxus are briefly described. The density of Rranchiostoma belcheri in the Huangcuo waters of Xiamen is highest. The Average density of amphioxus is so low that has no economic significance in some new distribution areas of amphioxus.
