辽东湾海域斑海豹幼崽的救助、病理解剖与死因分析

Rescue, pathological anatomy and analysis of death causes for wild Phoca largha pups in Liaodong Bay Sea area

2020年3月—2021年3月,辽东湾海域先后发现3头体质虚弱的斑海豹幼崽,发现后立即送至辽宁省海洋水产科学研究院进行救助。经几日救助后,斑海豹幼崽的身体状况并未得到明显改善,最终死亡。文章记录了3头斑海豹幼崽的外部形态特征,通过解剖对其死因进行分析。病理解剖发现:3头斑海豹幼崽均有不同程度内脏组织出血现象,其中1头斑海豹幼崽因食道堵塞、胃动力不足和胃内异物引起的胃炎而死;另外2头斑海豹幼崽虽然食道及胃黏膜正常,但肺部有明显的炎症并伴有败血症。

From March 2020 to March 2021, three wild Phoca largha pups were found in the Liaodong Bay Sea area and transported to the Liaoning Ocean and Fisheries Science Research Institute for further rescue. After several days of rescue,the physical condition of the Phoca largha pups did not improve significantly and eventually died. The article describes the external morphological features of three Phoca largha pups, and analyzes the cause of death through autopsy. Pathological anatomy found that three Phoca largha pups had different degrees of visceral tissue hemorrhage, and one of the Phoca largha pups died of gastritis caused by esophagus blockage, insufficient gastric motility and foreign bodies in the stomach.Although the esophagus and gastric mucosa of the other two spotted seal pups were normal, the lungs had obvious inflammation and sepsis.
