海南两头活体搁浅瑞氏海豚的血检指标及死因分析

Analysis of blood test index and cause of death of two live stranded Grampus griseus in Hainan

近几年,瑞氏海豚(Grampus griseus)在中国海南搁浅的案例较多。瑞氏海豚(A、B)分别搁浅于海南省万宁和乐镇大花角海域和文昌市铺前镇木兰湾海域,均因伤势和病情过重死亡。本研究检测了2头瑞氏海豚的血常规和血液生化指标,并通过解剖对其死亡原因进行分析。检测结果显示,2头海豚皮下脂肪较薄,均有营养不良的表现,并且2头海豚血液中红细胞总数、血红蛋白含量与红细胞平均体积均高于正常范围。尸检结果显示,瑞氏海豚内脏炎症出血严重,呼吸系统和消化系统存在大量寄生虫,并且消化系统内无食物以及其他异物。瑞氏海豚A是由于体表外伤感染引发并发症而导致死亡;瑞氏海豚B呼吸系统和消化系统被大量寄生虫寄生,并且搁浅时间久表现严重高渗性脱水,多器官病变,最终全身败血而亡。本研究通过检测搁浅瑞氏海豚的血常规和血液生化指标,同时进行病理解剖分析其死因,为搁浅海豚的救助工作提供参考数据,具有较高的理论参考价值和科研价值。

There were many cases of Grampus griseus stranding in Hainan Province in recent years.Grampus griseus(A and B)were found stranded in the waters of Dahuajiao,Wanning Hele Town,Hainan Province,and Mulan Bay,Puqian Town,Wenchang City,Hainan Province,respectively,and both died of their injuries and illnesses.In this study,blood routine and blood biochemical indexes of two dolphins were detected,and the cause of death was analyzed by anatomy.The results showed that the subcutaneous fat of the two dolphins was thin,and they were all malnourished,and RBC,MCH and MCV in the blood of the two dolphins were higher than the normal range.The death of Grampus griseus A was caused by complications caused by body surface trauma infection;The respiratory system and digestive system of dolphin B were infested by a large number of parasites,and due to the long time stranded,it showed severe hyperosmolar dehydration,multiple organ lesions,and eventually died of systemic septicemia.In this study,blood routine and blood biochemical indexes of stranded Grampus griseus were detected,and the cause of death was analyzed by pathological autopsy,which provided reference data for the rescue work of stranded dolphins and had high theoretical reference value and scientific research value.
