This book explores the development of the goldfish from a single fertilized egg and how domestication has altered this process. It includes high-quality live images of embryonic and larval stages, detailed descriptions of skeletogenesis supported by fluorescent microscopic and histological images, and advanced interpretations of the interplay between artificial selection and developmental processes. Additionally, it discusses future applications of genome editing in ornamental goldfish breeding and provides methodological insights into goldfish developmental biology. As a widely popular ornamental fish, goldfish exhibit diverse morphological features and color variations that attract enthusiasts. They have been distributed globally by breeders and serve as experimental subjects in life science research. Despite this, there is a lack of scientific literature detailing their embryogenesis and morphogenesis. This publication aims to fill that gap, offering valuable information for researchers in developmental biology, evolutionary biology, zoology, aquaculture, and fishery science, as well as for goldfish fanciers and breeders. The contents include an introduction, discussions on goldfish as a model organism, morphological varieties, development, mutant strains, evo-devo questions, challenges, and an experimental appendix.
