中文摘要:
      为分析筏式养殖虾夷扇贝贝壳内侧褐色沉积症状形成机制,讨论虾夷扇贝夏季大规模死亡和褐色沉积症状相关性。2017-2019年开展流行病学调查,3- 10月调查虾夷扇贝褐色沉积症症状发生过程和出现比例,统计虾夷扇贝累计死亡率;设计防咬合扇贝养殖笼,统计调查出现褐色沉积症扇贝比例;利用傅里叶红外光谱分析法分析褐色沉积物质成分,讨论内在形成原因;结果表明:扇贝间互相咬合导致的损伤并不是褐色沉积症出现原因;褐色沉积物质主要成分为蛋白质;虾夷扇贝褐色沉积症出现时间具有规律性,且与扇贝开始死亡时间吻合,褐色沉积症和筏养虾夷扇贝夏季死亡具有相关性,其形成原因可能与病原菌感染相关。
英文摘要:
      Since 2007 , the raft culture scallops Pationopecten yessoenisis outbreak massive mortality in ChangHai Liaoning. The moribund scallops exhibited severe disease signs including brown deposit on the inner shell. For analyzing the cause of brown deposit symptom and the relationship with death of scallop, the epidemiological investigation and experiment of avoiding bite were used for research. The infrared spectroscopy scanning also was used for studying the component of brown deposit. The result show that the biting or mechanical abrasion by other scallops was not the cause of brown deposit symptom. The main component of brown deposit was protein. The brown deposit symptom often happened in mid late June and early July when the temperature of seawater was 17℃. So pathogenic infection maybe the cause of brown deposit symptom, and it had relationship with the massive mortality of scallops.
