Shahr-e Sukhteh (meaning burnt city in Persian) in Iran is an archeological site dated back to around 3,200-1,800 BC. It is located in Sistan and Baluchistan Province of Iran and known as the junction of Bronze Age trade routes crossing the Iranian plateau. It was appointed as current study area for paleoparasitological investigations. Excavations at this site have revealed various archeologica...

Diseases have been the bottle-neck to sustainable development of sturgeon cultivation. Bacterial septicemia that caused mass mortalities of sturgeons is still prevalent in Shanxi and Yunnan provinces in China. The epidemiology and pathogenicity of the disease were investigated. Four predominant isolates of bacteria were isolated from Siberian sturgeons (Acipenser baerii) suffering from bacteria...

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 &muL isopropyl &beta-D-1-thiogalactopyranoside (IPTG) was added for induction of GH synthesis. Samples were taken every 2 hours an...

 Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...

Challenges and regulations associated with handling fish during fisheries management activities have increased efforts to achieve U.S. Food and Drug Administration approval for an immediate-release sedative for fish. The objectives of this study were to (1) identify the target concentration of AQUI-S 20E for sedation of Pallid Sturgeon Scaphirhynchus albus to a handleable state followed by rapi...

A high resolution three-dimensional numerical model, COCIRM, was adapted and optimized to predict the potential impact of the Waneta Expansion Project (WEP) on the flow conditions at the confluence of the Columbia and Pend d’Oreille rivers. Flows in this confluence area represent important habitat features for white sturgeon, including the well-developed low-speed Waneta Eddy for sturgeon reari...

The objective of this study is to provide information on metabolic changes occurring in Chinese sturgeon (an ecologically important endangered fish) subjected to repeated cycles of fatigue and recovery and the effect on swimming capability. Fatigue-recovery cycles likely occur when fish are moving through the fishways of large dams and the results of this investigation are important for fishway...

During teleost ontogeny the larval and embryonic stages are key stages, since failure during this period of tissue differentiation may cause malformations, developmental delays, poor growth, and massive mortalities. Despite the rapid advances in sequencing technologies, the molecular backgrounds of the development of economically important but endangered fish species like the Atlantic sturgeon ...

 This study was conducted in two phases on sturgeon larvae and fingerlings produced from artificial breeding of five pairs of the Persian sturgeon (Acipenser persicus) broodstocks in Shahid Beheshti Hatchery in spring and summer 2006. Initially, 600 larvae were collected on 3 post days hatching (pdh) and 5 days after the onset of exogenous feeding. The second phase was conducted with 450 specim...
