金鱼，Carassius auratus，广泛分布于欧亚大陆，是最早被驯化用于观赏目的的鱼类之一。由于金鱼的高密度养殖，爆发了一系列疾病，造成了重大的经济损失。在这里，我们首次报告了与中国河南省安子营镇一个养鱼场金鱼转移到几个水族馆后高死亡率相关的小林圆齿虫感染。在金鱼（n= 4200，体重10.24±1.45 g）转移到水族箱后的前2周内，总共损失了3335条金鱼，占初始放养生物量的79.4%。经检验，该批鱼除g外未检出其他致病菌。kobayashii。g的沉重负担。kobayashi /fish（264.7，范围100-450）是高死亡率的主要原因，尽管这不是唯一原因。此外，g。报道了河南金鱼（C. auratus）的种类。形态学鉴定采用形态计量学测量和寄生物硬部的绘图。基于跨5.8S和ITS-2的参考DNA序列的系统发育分析进行分子描述。重要的是，本研究首次提供了g的附着器官的完整的25点对点形态测量和高分辨率图像。kobayashii。
Goldfish,Carassius auratus, widely distributed across Eurasia, is one of the earliest fish domesticated for ornamental purposes. A series of diseases break out due to high-density culture of goldfish, causing significant economic losses. Here, we report for the first time an infection ofGyrodactylus kobayashiiassociated with the high mortality of goldfish from a fish farm in Anziying township of Henan province, China, following their transfer to several aquariums. In the first 2 weeks after goldfish (n= 4200, weight 10.24 ± 1.45 g) transfer to aquariums, a total of 3335 goldfish were lost, representing 79.4 % of the initial stocked biomass. The examination showed that no other pathogens were found in this batch of fishes, except forG. kobayashii. The high burdens ofG. kobayashii/fish (264.7, range 100–450) were the primary reason for the high mortality, although this was not the sole cause. In addition, the isolate ofG. kobayashiifrom goldfish (C. auratus) in Henan province of central China was described. The morphological characterization was performed using morphometric measurements and drawings of opisthaptoral hard parts of the parasites. The molecular description was performed based on phylogenetic analysis of a reference DNA sequence spanning 5.8S and ITS-2. Importantly, the present study provides for the first time a full 25 point-to-point morphometric measurements and high-resolution images of attachment organ ofG. kobayashii.
