Fig. 3

Survival rates of Russian sturgeon Acipenser gueldenstaedtii embryos incubated at different temperatures (12, 16, or 20 °C). Abbreviations for selected stages are fertilization (Fer), early blastula (Bla; cleavage cavity identified), onset of gastrulation (Gas; dorsal lip formed), formation of small yolk plug (SYP; 90% epiboly cover), late neurulation (LN; just closed of neural tube), s-heart formation (SHF; onset of heart beating), and first hatching (FH; occurrence of the first advanced hatching). Fertilization rate was assessed by the percent embryos showing typical second cleavage furrow at animal hemisphere. Means with different letters indicate significant difference based on ANOVA at P < 0.05
