Highly divergent morphology among the different goldfish strains (Carassius auratus) may make it a suitable model for investigating how artificial selection has altered developmental mechanisms. Here we describe the embryological development of the common goldfish (the single fin Wakin), which retains the ancestral morphology of this species.
We divided goldfish embryonic development into seven periods consisting of 34 stages, using previously reported developmental indices of zebrafish and goldfish. Although several differences were identified in terms of their yolk size, epiboly process, pigmentation patterns, and development rate, our results indicate that the embryonic features of these two teleost species are highly similar in their overall morphology from the zygote to hatching stage.
These results provide an opportunity for further study of the evolutionary relationship between domestication and development, through applying well-established zebrafish molecular biological resources to goldfish embryos.
不同金鱼品种（Carassius auratus）之间形态差异很大，这可能使其成为研究人工选择如何改变发育机制的理想模型。在这里，我们描述了普通金鱼（单鳍鲫鱼）的胚胎发育过程，这种金鱼保留了该物种的祖先形态。
我们使用先前报道的斑马鱼和金鱼的发育指数，将金鱼胚胎发育分为 7 个时期，共 34 个阶段。尽管在卵黄大小、外包过程、色素沉着模式和发育速度方面存在一些差异，但我们的结果表明，这两种硬骨鱼物种的胚胎特征在从受精卵到孵化阶段的整体形态上高度相似。
这些结果为通过将成熟的斑马鱼分子生物学资源应用于金鱼胚胎，进一步研究驯化与发育之间的进化关系提供了机会。
