摘要
本文对莱州湾东部水域出现的文昌鱼幼体进行了初步调查。该水域的文昌鱼幼体分布面较广，从５ｍ 到１２ｍ等深面上均有很高的出现频率和一定的生物量。６－８月间文昌鱼幼体体长为１．３ｍｍ－７．８ｍｍ，进入８月份后，幼体变态转入底栖潜沙生活。
The young Branchiostoma belcheri found in the east area of Laizhou Bay was studied. Its distribution in this area was relatively extensive, the appearing frequency from 5 to 12m was very high and there was certain biomass. The length of young Branchiostoma belcheri from June to August was l.3mm-7.8mm. From August, it metamorphosed and shifted to the bottom life.
