摘要：

根据2006—2007年对珠江口水域20个站位进行的鱼类浮游生物调查资料, 着重研究鱼类浮游生物的种类组成、优势种和数量分布状况, 就其数量分布变化与水文、环境因子的关系进行分析和探讨。结果表明: 珠江口鱼类浮游生物共113种(类), 其中, 春季种类最多。各季节间的鱼类浮游生物群落相似性差异不明显。鱼卵优势种共有4种, 仔稚鱼有6种。其中鱼卵优势种类主要有康氏小公鱼、棱鳀、鲾和叫姑鱼, 仔稚鱼优势种类主要为小沙丁鱼、康氏小公鱼、鲾、叫姑鱼、鰕虎鱼和鱼衔。鱼类浮游动物丰度的季节变化较为明显, 鱼卵丰度春季最高, 仔稚鱼丰度夏季和春季较高。鱼类浮游生物的主要分布区域受制于珠江径流和潮流的消长。

Abstract:

Based on the results from four cruises of oceanographic survey carried out in 2006 to 2007 in the Pearl River Estuary, the species composition, dominant species and abundance distribution of ichthyoplankton were studied. The abundance distributions with hydrological characteristic and environmental factors were also analyzed. A total of 113 ichthyoplankton taxa were identified, and the species of ichthyoplankton in spring were more than those in the other seasons. There were four dominant species of fish eggs: Stolephorus commersonii, Thryssa sp., Leiognathus sp. and Johnius sp. There were six dominant species of fish larvae: Sardinella sp., Stolephorus commersonii, Leiognathus sp., Johnius sp., Gobiidae gen. sp., and Callionymus sp. The variation in the abundance of four seasons was conspicuous. The largest abundance of fish eggs occurred in spring, and the largest abundance of fish larvae occurred in both spring and summer. The variation of the Pearl River runoff and tide was important influential to the distribution of ichthyoplankton.

Key words: ichthyoplankton, fish egg, fish larvae, species composition, abundance distribution, Pearl River Estuary
