摘要
本文根据 1997年至 2 0 0 0年在东海 (2 7°～ 32°30′N、12 8°E以西 )的大型浮游动物垂直拖网调查结果 ,对毛颚动物的种类组成、数量分布进行分析比较 ,浅述其数量分布变化与水系、渔场的关系。结果表明 :海区种类组成以春、夏季最为丰富 ,数量则以秋季最高 ;高数量密集区处于各水系的交汇处 ,基本上反映了不同季节水系消长动态变化过程 。
The present paper is based on samples collected with large zooplankton net from bottom to surface in the East China Sea (27°-32°30′N,west of 128°E) during 4 surveys from 1997 to 2000. After analyzing the species composition and quantity distribution, and comparing the relationship between quantity distribution and water system, we found that the species composition of Chaetognatha was the richest in spring and summer, but the peak of quantity appeared in autumn; and the concentration zone was located at the region of mixed water system which reflected the changing of water system in different seasons and gave a certain indication of the formation of water system and fishing grounds.
