跨界水生动物疾病是用于加强该区域水生动物健康管理能力的主要关心的问题之一。这些疾病的传播表明了水产养殖业的脆弱性,以及野生鱼类种群,与疾病的发生,其中影响已经被缺乏准备的加剧。NACA的水生动物卫生计划,成立于1998年,为地方政府的机制来协调疾病防备,监测和应对。 P>
的出现和新的或以前未知的传染病蔓延,对公共卫生,粮食安全和国际贸易非常显著的影响。病出现是破坏病原体及其自然宿主之间的关系,生态环境和/或社会变化的结果。了解疾病发生的司机将帮助我们开发出将减少疾病的发生机会,水产养殖,提高遏制前景的政策和做法。 P>
归在畜牧业是其中动物种群响应于养殖生产系统的人工环境改变的过程。 Significant and widespread economic gains have been achieved through genetic improvements made through domestication and selective breeding of commercially farmed shrimp species, particularly Litopenaeus vannamei. Different policies on the translocation of shrimp genetic resources have influenced the approaches to shrimp domestication in different countries. The present paper examines the different approaches.
In early 2013, Vibrio parahaemolyticus was discovered as the causative agent of acute hepatopancreatic necrosis disease (AHPND). Subjecting 4 arbitrarily selected V. parahaemolyticus isolates obtained from a single farm in November 2012 to the previously reported immersion challenge protocol, we confirmed that 3 caused high mortality at different rates accompanied by characteristic lesions of AHPND while 1 caused high mortality without such lesions. Virulence may be determined by mobile genetic elements such as plasmids or bacteriophages.
热带对虾养殖正面临着可通过交互管理实践原因近亲繁殖,而放大由之间的易感性近交疾病和其它应力被推进的疾病的危机。 Broodstock accumulate inbreeding and lose genetic diversity when they experience bottlenecks or are chronically too small. The genetic lock is a practice that leads to inbreeding at farm level. Inbreeding may be amplifying the severity of diseases, including the major current threats.
