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.....}, keywords = {}, title_fa = {مطالعه رشد و نمو جنینی ماهی سفید Rutilus frisii kutum kamensky}, abstract_fa = {مطالعه رشد و نمو جنینی ماهی سفید Rutilus frisii kutum kamensky}, keywords_fa = {رشد و نمو,جنینی ماهی سفید,Rutilus frisii kutum kamensky}, url = {https://isfj.areeo.ac.ir/article_116172.html}, eprint = {https://isfj.areeo.ac.ir/article_116172_657057c82a4a7b9b13b6864b5e5e79cd.pdf} } @article { author = {Zarshenas, Gh.}, title = {Behavioural habits of Banana shrimp in the Southern waters of Iran (Hormouzgan province) }, journal = {Iranian Scientific Fisheries Journal}, volume = {1}, number = {1}, pages = {25-30}, year = {1993}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1026-1354}, eissn = {2322-5998}, doi = {10.22092/isfj.1993.116173}, abstract = { - Banana shrimp or Penaeus merguiensis is the most important shrimp species in Hormuzgan waters.
