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 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 کاملOxygen consumption and swimming behavior of juvenile Siberian sturgeon Acipenser baerii during stepped velocity tests
Oxygen consumption rate (MO2) and critical swimming speed (Ucrit) of juvenile Siberian sturgeon Acipenser baerii were measured at 24°C using a step-wise velocity test in a flume-type respirometer. Swimming behavior was video-recorded before and after the swimming experiment in a respirometer and an open tank. The relationship between MO2 and swimming speed (U) can be accurately described by a p...
متن کاملTesting 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...
متن کاملExpression 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...
