in this study escherichia coli de3 containing expression vector (pet21a) with cloned persian sturgeon growth hormone (psgh) gene was grown in 10 ml lb broth on a 150 rpm shaker, at the temperature of 37 °c. at the late log phase (determined by od standard curve) 100 μl isopropyl β-d-1-thiogalactopyranoside (iptg) was added for induction of gh synthesis. samples were taken every 2 hours and afte...

 In order to have a sustainable management on Persian sturgeon as a highly commercial species in the South Caspian Sea, we need to identify its population structure and the level as well as its conservation status in their natural habitat. To develop a conservation program for this all Caspian Sea' sturgeon species it requires knowledge of its genetic diversity using reliable molecular marker t...

administering growth hormone increases growth rate of cultured fish. the aim of this study was isolation and synthesize of persian sturgeon gh cdna. the total rna was extracted from pituitary gland of persian sturgeon and cdna was synthesized. the full-length cdna sequence of persian sturgeon contains a 645 nucleotide open reading frame, which encoding a 214 amino acid residues. the position of...

A partial sequence of the mtDNA ND5 gene region was used for population study in Persian sturgeon (west and east areas of southern Caspian Sea). The result showed that although this approach was informative for phylogenetic study in sturgeon, it was less informative for population study in Persian sturgeon. 

Understanding the scale at which wild stocks of Persian sturgeon (Acipenser persicus) are genetically discrete is necessary for effective management of this commercially important species. Disomic DNA microsatellite markers are among the best tools for determining stock structure in fishes. As all sturgeon species have a polyploid ancestry of all sturgeons, most gene loci exhibit more than two ...

Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) experienced severe declines due to habitat destruction and overfishing beginning in the late 19(th) century. Subsequent to the boom and bust period of exploitation, there has been minimal fishing pressure and improving habitats. However, lack of recovery led to the 2012 listing of Atlantic sturgeon under the Endangered Species Act. Although ha...

This study was aimed to observe the correlations among egg, larvae and maternal characteristics of Persian sturgeon. A total of 41 females were used and the variables including fertilization rate, incubation survival rate, larvae survival rate during yolk sac absorption (before feeding), and larvae survival rate after first feeding were determined. As a result, fertilization rate was positively...
