Evolutionary relations and population differentiation of Acipenser gueldenstaedtii Brandt, Acipenser persicus Borodin, and Acipenser baerii Brandt
Russian ( Acipenser gueldenstaedtii), Persian ( A. persicus) and Siberian ( A. baerii) sturgeons are closely related 'Ponto-Caspian' species. Investigation of their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, 'baerii-like' mitotypes were found in the Caspian Sea among 35% of Russian stu...

متن کاملAssessment in Vitro Oocyte Maturation and Blood-Circulating Steroid Hormones in Persian Sturgeon (Acipenser Persicus) Spawning
The in vitro effect of 17α, 20β-Dihydroxyprogesterone on the maturation of Persian sturgeon (Acipenser persicus) oocytes for 7, 10, 12, 24 and 30th hours of incubation were investigated. Blood serum, testosterone (T), progesterone (P4) and 17-β estradiol concentrations were measured using enzyme-linked immuno-sorbent assay (ELISA). The oocytes were incubated in SIS, RM2, L-15 and PSACF media in...
متن کاملOntogeny of respiration and feeding structures of skull in Persian sturgeon, Acipenser persicus (Bordin, 1897)
In the present study, the process of the skull development and calcification in Persian sturgeon (Acipenser persicus) was studied. Development of cartilage started after hatching around the head and notochord (10.6 mm, total length, TL) and the first calcification process occurred in dermopalatine and dentary bone jaw coincident with mixing feeding. The appearance of dermal skeletal on the body...
متن کاملMorphological and Histological Study of Kidney in Juvenile Great Sturgeon (Huso huso) and Persian Sturgeon (Acipenser persicus)
Sturgeons are ancient and commercial fishes which posses’ primitive characteristics and due to their great inflections are able to live in both freshwater and marine environments. So their kidney has great ability for adaptation process. In order to find the structure and distribution of kidney nephrons in juvenile Huso huso and Acipensr persicus, sampling of head, body and caudal parts of kidn...
