我们对沈阳地区麦穗鱼鱼体不同部位的华支睾吸虫囊蚴的大小及其分布进行了观察。从头、鳞、肌肉处分离出的囊蚴各取50个进行测量,结果:囊蚴大小分别为144.84±8.46×117.98±9.67μm、142.32±7.14×118.46±9.231μm和140.225±10.20×114.85±8.88μm;表明寄生部位对囊蚴大小的影响不明显(p>0.05)。观察20尾麦穗鱼,囊蚴在鱼体内各部位的分布为:肌肉占91.65%、头4.97%,鳞3.39%。
We observed the size and distribution of Clonorchis sinensis metacercaria in different parts of the mandarin fish in Shenyang area. The results showed that the size of metacercariae were 144.84 ± 8.46 × 117.98 ± 9.67μm, 142.32 ± 7.14 × 118.46 ± 9.231μm and 140.225 ± 10.20 × 114.85 ± 8.88 respectively μm. The results showed that the parasitoid had no obvious effect on the size of metacercariae (p> 0.05). Eighteen spikelets were observed. The distribution of metacercariae in the fish was 91.65% in muscle, 4.97% in head and 3.39% in scales.
