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、孔虎鱼、红狼牙虎鱼、触角沟虎鱼、矛尾虎鱼、拟矛尾虎鱼、眶棘双边鱼、双线舌鳎、半滑舌鳎、凤鲚、勒氏短须石首鱼、丽叶、前鳞骨鲻、龙头鱼、带鱼、短带鱼、小带鱼、鳓鱼、黄鲫、日本、康氏小公鱼、黄吻棱、棕腹刺、黄鳍东方、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。
According to the survey data of monthly fisheries resources in the Pearl River Estuary in 1998, the species composition, biological characteristics and seasonal variation of fish in the Pearl River Estuary were analyzed by means of factor analysis, regression analysis and cluster analysis. The results showed that the fish species in the Pearl River Estuary are mainly small-sized coastal fish or estuarine fish, Tiger fish, lanceolate goby, gorgonian goby, orbital spinous double-sided fish, double tongue gaggle, half smooth tongue gizzard, , Octopus, short-necked fish, small octopus, mackerel, yellow crucian carp, Japanese prickly heat, Corvus small male fish, yellow kisses edge , palm belly , yellow fin Eastern , muskets squid, The main component of fish.
