Embryonic development of goldfish (Carassius auratus): a model for the study of evolutionary change in developmental mechanisms by artificial selection.

Tsai HY, Chang M, Liu SC, Abe G, Ota KG - Dev. Dyn. (2013)

Bottom Line: 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.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.

Adult goldfish specimens. A: Lateral view of the common goldfish (the single fin Wakin) strain. B: Illustrations of two goldfish strains by Watase (1887). B-1: Ventral view of the bifurcated anal fin of Ryukin strain. B-2: Dorsal view of Ryukin strain. B-3, 4: Ventral and dorsal views of Ranchu strain; the dorsal fin is absent in this strain. B-5: Lateral view of the Ryukin strain. C: A pond with several goldfish in Taiwan. D: Artificially squeezed goldfish eggs on Teflon dishes. Approximately 500 to 1,000 eggs can be obtained from a single female (approximately 10 cm in length).

Mentions: The goldfish (Carassius auratus) is a well-known domesticated species (Fig. 1). According to analyses of Chinese archives, breeding of this teleost fish as an ornamental animal dates back around 1,000 years ago (Chen, ,; Smartt, 2001).
