Sturgeon and paddlefishes (Acipenseriformes) are cultured worldwide for commercial and conservation purposes. Over the past decade, we have learned many sturgeon culture programs experience spontaneous autopolyploidy, or the generation of triploidy without management intervention. Spontaneous autopolyploidy has been shown to negatively impact the physiology, reproductive development and fertility of sturgeon. Given these concerns, it is necessary to understand how it arises, how it affects production, and how it can be managed. The goal of this review is to describe the incidence of spontaneous autopolyploidy in sturgeon relative to other fishes, explain how spontaneous autopolyploids are formed, and report what is known about how triploidy and intermediate ploidy effect sturgeon reproductive development and physiology. We then describe four common methods for detecting spontaneous autopolyploids and their intermediate ploidy progeny and end with recommendations for reducing the incidence of spontaneous autopolyploidy based on the results of recent research. Although spontaneous autopolyploidy may never be completely eliminated from sturgeon culture, following these recommendations may significantly decrease its incidence.

worldwide鱼和pad鱼在世界范围内养殖用于商业和保护目的。在过去的十年中，我们了解到许多st鱼养殖计划都经历了自发的多倍体繁殖，或者在没有管理干预的情况下产生了三倍体。自发多倍体已被证明会对to鱼的生理，生殖发育和生育能力产生负面影响。考虑到这些问题，有必要了解它如何产生，如何影响生产以及如何进行管理。这篇综述的目的是描述st鱼相对于其他鱼类的自发多倍体发生率，解释自发多倍体如何形成，并报道三倍体和中间倍体如何影响st鱼的生殖发育和生理。然后，我们介绍了四种检测自发性多倍体及其中间倍性后代的常用方法，并根据最近的研究结果，提出了减少自发性多倍体发生率的建议。尽管自发多倍体可能永远不会从from鱼培养中完全消除，但遵循这些建议可能会大大降低其发生率。
