Abstract

Wild sturgeon populations have declined dramatically worldwide due to habitat degradation, such as river fragmentation, caused by anthropogenic pressures including legal and illegal overfishing and pollution. Rearing and releasing juvenile fish into natural water bodies is one method to restore biological resources. This study aimed to: (1) examine the spectrum of conditionally pathogenic bacteria causing pathological processes in domesticated sterlet (Acipenser ruthenus Linnaeus, 1758); (2) investigate the effects of pathogenic bacteria on fish internal organs using combined histological techniques for tissue treatment; (3) identify tissues as biomarkers for assessing the impact of bacterial co-infection in sturgeon; and (4)evaluate the role of these infections in fish domestication. Liver damage was the primary clinical manifestation during co-bacterial infection in all tested fish. Additionally, shifts in liver cell functions and cytological characteristics were observed.

粗斑鲟在驯化过程中肝脏结构的变化：初步数据

由于合法和非法的过度捕捞和污染等人为压力造成的栖息地退化，例如河流破碎，世界范围内的野生鲟鱼数量急剧下降。将幼鱼放归自然水体是恢复生物资源的一种方法。本研究的目的是：(1)研究引起家养小鱼（acpenser ruthenus Linnaeus, 1758）病理过程的条条性致病菌谱；(2)采用联合组织学技术研究病原菌对鱼类内脏器官的影响；(3)鉴定组织作为评估细菌共感染对鲟鱼影响的生物标志物；(4)评价这些传染病在鱼类驯化中的作用。肝损害是所有受试鱼共菌感染期间的主要临床表现。此外，观察到肝细胞功能和细胞学特征的变化。
