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.

Indices for staging of gastrula period embryos. A,B: Schematic drawing of early (A) and late (B) gastrula embryos. The percentage of epiboly and blastopore closure are defined as a percentage of l. bd.AV/l. ent.AV and dia.bp/dia. DV, respectively. dia.bp, diameter of blastopore; dia.DV, diameter of embryo along dorsal–ventral axis; l.bd.AV, length of blastoderm along the animal–vegetal pole axis. L.ent.AV. length of entire embryo along the animal–vegetal pole axis.

fig09: Indices for staging of gastrula period embryos. A,B: Schematic drawing of early (A) and late (B) gastrula embryos. The percentage of epiboly and blastopore closure are defined as a percentage of l. bd.AV/l. ent.AV and dia.bp/dia. DV, respectively. dia.bp, diameter of blastopore; dia.DV, diameter of embryo along dorsal–ventral axis; l.bd.AV, length of blastoderm along the animal–vegetal pole axis. L.ent.AV. length of entire embryo along the animal–vegetal pole axis.

Mentions: To overcome this difficulty, we defined the “percentage of blastopore closure” as an additional index for the staging period; equivalent indices (for example, “yolk plug closure” and “area of blastoderm“) were used in earlier studies of zebrafish, other teleost species, and amphibians (Kimmel et al., 1989; le Pabic et al., 2009; Latimer and Jessen, 2010; Kim et al., 2010). This index refers to the ratio between the maximum diameter of the blastopore and that of the blastoderm-covered yolk region along the DV axis (Fig. 9).
