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....
متن کاملComparison 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...
متن کاملThe effects of different levels of Aloe vera extract on some of the hematological and non-specific immune parameters in Siberian sturgeon (Acipenser baerii)
In this study, Aloe vera extract was used to evaluate its effects on hematological and immune parameters of Siberian sturgeon (Acipenser baerii). A total of 360 Siberian sturgeon weighing on average 10.95±0.04 g were randomly distributed in four treatments including a control group and three experimental groups (each with three replications). A. vera extract powder at the rate of 0.5%, 1% and ...
متن کاملEffects of selenium (Sel-Plex) supplement on blood biochemical parameters of juvenile Siberian sturgeon (Acipenser baerii)
Selenium (Se) and many of its compounds are among the most toxic micronutrients. Therefore, determining the optimal level of selenium in the diet of fish is one of the main concerns of researchers. The present study was designed to investigate the effects of Sel-Plex® (Selenium-enriched Saccharomyces cerevisiae yeast) on blood biochemical parameters in juvenile Siberian sturgeon, Acipenser baer...
متن کاملEffects of natural polymer (Poly-β-hydroxybutyrate) and its degrading bacteria on lipid metabolism and digestive tract pH in Siberian Sturgeon Acipenser baerii Brandt, 1869 fingerlings
Five hundred and ninety two Siberian sturgeon (A. baerii) fingerlings (average weight, 11.1±0.9 g) were randomly distributed in 16 tanks (150 L) at a density of 35 fish per tank and fed different treatments (Control, degrading bacteria, 2% PHB, degrading bacteria + 2%PHB) for 60 days. At the end of the experiment, the results indicated that the fish fed PHB or bacteria treatments had low midgut...
