| Abstract: | Artificial propagation of Esox lucius was conducted in Changchun area.The development of embryo and yolk-sac larva of Esox lucius was observed.The results showed that eggs of Esox lucius are sticky and spherical shape in golden yellow color.There are many small oil drips on the surface of yolk-sac of Esox lucius.The diameters of the eggs are from 1.8 to 2.1 mm.Under 10-14℃,they take 188 hours from fertilization to hatching with the effective accumulated temperature of 2 244 ℃ · h.Under 12-14 ℃,they need 10 d from hatching stage to yolk-sac absorbed stage,and the effective accumulated temperature of 120-140 ℃ · d is necessary.The fertilization rate is 73.3％,hatching rate is 48.5％. |
