| چکیده [English] | ||
| The chronological development of Rutilus frisii kutum (kamensky),, from Caspian Sea was investigated.Artifical propagation was carried out by strip-ping sperm on the eggs. The gamets were gently mixed for 5 minutes, then incubated at 1-1- 16c in 8 liter glass incilbatores. Development of embryos including, organogeuesis and different choronological devellopmental stages were followed up morphologically and histologically. As the cborion is semitransparent in this species, we forced to dechorionate the eggs. So the chorionic is evelops of the embryos were removed under stereornitransparent using two fine needles_ Weight and length of the samples at each stage were measured for statistical analysis. The embryos were prepared for serial sectioning and microscopic studies. The developmental stages were investigated from 5 minutes alter fertilization up to day 30_ Fertilized eggs cleaved., and gastrulation began within 24-30 hours, Most of the embryos began to batch out of chorion (Vitell..... | ||
