中文摘要:
      根据1998年珠江口水域尖尾罟网和掺缯网周年月度渔业资源调查资料,采用因子分析、回归分析和聚类分析方法分析了珠江口鱼类的种类组成、生物学特征及季节变化规律。结果表明,珠江口水域的鱼类主要是沿岸或河口性的小型鱼类,棘头梅童鱼、皮氏叫姑鱼、银鲳、孔Jia虎鱼、红狼牙Jia虎鱼、触角沟Jia虎鱼、矛尾Jia虎鱼、拟预选尾Jia虎鱼、眶棘双边鱼、双线舌鳎、半滑舌鳎、凤鲚、勒氏短须石首鱼、丽叶Shen、前鳞骨鲻、龙头鱼、带鱼、短带鱼、小带鱼、鳓鱼、黄鲫、日本Ti、康氏小公鱼、黄吻棱Ti、棕腹刺Tun、黄鳍东方Tun、火枪乌贼、杜氏枪乌贼等,是珠江口鱼类组成的主体。鱼类组成的季节变化明显,但底栖种类和中上层种类存在着时间上的差异。
英文摘要:
      Based on monthly investigation data of beam trawl and hang trawl in the Pearl River estuarine waters in 1998, the paper analysed species composition, bio logical characteristics and seasonal variat ion of f ishes by principal components, regression, and hierarchical cluster analysises. The results indicated that fishes in the waters consisted of coastal or estuarine small species, among them, Collichthys lucidus, Johnius belengeri , Pampus argenteus, Trypauchen vagina, Odontamblyopus rubicundus , Oxyurichthys tentacularis , Chaeturichthys stigmatias, Parachaeturichthys polynema, Ambassis gymnocephalus , Cynoglossus bilineatus, Cynoglossus semilaevis, Coilia mystus, Umbrina russelli , Caranx kalla, Osteomugil ophuyseni , Harpodon nehereus , Trichiurus haumela, Trichiurus brevis , Euplerogrammus muticus , Ilisha elongata, Setipinna taty , Engraulis j aponicus, Stolephorus commersoni , Thrissa vitirostris , Gastrophysus spadiceus, Fugu xanthopterus , Loligo beka and Loligo duvaucelii are principal parts of f ishery resources. Seasonal variation in species composit ion was obvious, and benthic group differed f rom pelagic group in the time of succession.
