大黄鱼（Pseudosciaena crocea）是我国重要的海水养殖经济鱼类。LYC年产量的变化与鱼病的发生有着密切的关系。此外，弧菌感染已被确定在这种鱼频繁。为了了解LYC中弧菌感染的模式，我们使用针对溶藻弧菌、哈氏弧菌和副溶血性弧菌的多重PCR方法对养殖LYC人群中的弧菌进行了一项独立于培养的调查。结果表明，在各采样点共检出3种致病性弧菌，检出率为6.7%~ 73.3%，但未发现单一种弧菌占优势。研究结果表明，三种弧菌仍然对养殖LYC的健康状况产生影响，LYC养殖需要更有效的预防策略。(C)2016作者（S）由Elsevier B. V.发布，这是CC BY许可下的开放获取文章。
Large yellow croaker (LYC), Pseudosciaena crocea is an economically important fish species of mariculture in China. The variation of yearly production of LYC has been increasingly related to the outbreaks of fish diseases. Moreover, Vibrio infections have been identified in this fish frequently. To understand the pattern of Vibrio infections in LYC, we conducted a culture-independent survey of Vibrios in farmed LYC populations using a multiplex PCR method targeting Vibrio alginolyticus, Vibrio harveyi and Vibrio parahaemolyticus. The results showed that three fish pathogenic Vibrios had been detected in LYC populations at each sampling with a prevalence ranging from 6.7% to 73.3% but no single species dominated the Vibrio infection. The findings indicate that three Vibrio species still have impact on health status of farmed LYC and LYC aquaculture requires more efficacious prophylactic strategies. (C) 2016 The Author(s).
