Effect of sodium orthovanadate on ovulation isolated ovarian follicles in Siberian Sturgeon (Acipenser baerii) In Vitro

Electrical excitability of the heart in a Chondrostei fish, the Siberian sturgeon (Acipenser baerii).

Sturgeon (family Acipenseridae) are regarded as living fossils due to their ancient origin and exceptionally slow evolution. To extend our knowledge of fish cardiac excitability to a Chondrostei fish, we examined electrophysiological phenotype of the Siberian sturgeon (Acipenser baerii) heart with recordings of epicardial ECG, intracellular action potentials (APs), and sarcolemmal ion currents....

Testing taxonomic boundaries and the limit of DNA barcoding in the Siberian sturgeon, Acipenser baerii.

DNA barcoding efforts involving animals have focused on the mitochondrial cytochrome c oxidase subunit I (Cox1) gene. Some authors suggest that this marker might under-diagnose young species. Herein, we examine Cox1 and control region diversity in a sample of Siberian sturgeon (Acipenser baerii), a species with an extremely wide geographic distribution in the major rivers of Siberia and in Lake...

Expression of growth hormone gene during early development of Siberian sturgeon (Acipenser baerii)

The mRNA expression of growth hormone (GH) gene in early development stages of Siberian sturgeon was investigated using RT-PCR method. Samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. Ribosomal protein L6 (RPL6) transcripts were used as the internal standard during quantification of GH mRNA expression. The results showed that the GH mR...

Comparison of growth and hematological parameters in juvenile Siberian sturgeon (Acipenser baerii), sterlet sturgeon (Acipenser ruthenus) and its hybrid (Acipenser ruthenus ♀ × Acipenser baerii ♂)

The present study was conducted to compare the growth indices and blood factors of sterlet (Acipenser ruthenus), Siberian sturgeon (Acipenser baerii) and their hybrid (Acipenser ruthenus ♀ × Acipenser baerii ♂) to produce a fish with larger size, larger eggs and more tolerant to environmental conditions than the parents. The hybrid was produced by mixing of the oocytes of one sterlet female wit...
