摘要: 在闽南厦门至漳浦沿海获22只江豚,根据背部棘状小结节的数量与分布,可明显分为两个亚种,即指名亚种(N.P.Phocaenoides,81%)和北方亚种(N.P.Sunameri,19%),表明本海域是几个亚种的混栖地带,分析了这些江豚的外部形态和种群结构,测定了脂肪层及各内脏的重量.Abstract: Twenty dead finless porpoises (Neophocaena phocaenoides) are got from the coastal waters between Xiamen and Zhangpu,Fujian Province.According to the prickles on the back,it is obvious that two subspecies.N.P.Phocaenoides (81.0%) and N.P.Sunameri (19.0%) occur simultaneously in this area.The morphology and population structure are studied,and blubber and inner organs are weighed.Furthermore,the stomach contents are analyzed carefully.
