Abstract:
... This study set out to examine the effects of thyroxine (T4) on reproductive success of female Sterlet sturgeon broodstock and subsequent growth and development of the larval offspring. Fish received four intraperitoneal injections of coconut oil (controls), 1 mg T4/kg body weight (BW) in coconut oil (T₁) or 10 mg T4/kg BW in coconut oil (T₁₀) over a 170-day treatment period. Ovulation was induced ...

Abstract:
... Polyspermy is the most commonly observed cause of embryonic abnormalities in fertilization, often resulting in death. In sterlet (Acipenser ruthenus), however, polyspermic embryos have high survival (similar to a control group) and morphological development is similar to monospermic larvae. Ploidy of these individuals is n/2n mosaic (whereas the normal state for A. ruthenus is a functional diploid ...

Abstract:
... The aim of the study was to develop a simple, rapid, and reliable technique to detect the pharmacokinetics and the residual of florfenicol (FFC) in Bester sturgeon, a cultured hybrid of Huso huso × Acipenser ruthenus by high performance liquid chromatography (HPLC) with UV detector. The results showed that the concentration-time course of the FFC was described by one-compartment model with 1st ord ...

Abstract:
... Most of the 27 species of sturgeons are endangered or close to extinction which is connected to habitat degradation, water pollution and overfishing. Conservation programmes are facing the problem of late maturation which can be reached between 5 and 11 years depending on the species and gender. The aim of our study was to investigate the possibility of shortening the sexual maturation using hormo ...

Abstract:
... One of the challenges of sturgeon aquaculture is that sturgeon takes an extended amount of time to reach sexual maturity. The pattern of the protein expression in relation to the late maturity of sturgeon can help to better understand changes in sexual maturity. 17β-estradiol (E2), testosterone (T) and vitellogenin (Vtg) levels were examined at all stages of sexual maturation in Sterlet sturgeon ( ...

Abstract:
... Abdominal distention occurred at an incidence of 1% (15 from 1500 fish) in the population of 1‐year‐old bester (Huso huso × Acipenser ruthenus). Computed tomography (CT) images and radiographs showed a soft tissue mass compressed the posterior part of the swim bladder. Ultrasonography showed that the masses had different patterns. Internal examination revealed the abdominal cavities to be filled w ...

Abstract:
... The Siberian sturgeon Acipenser baerii and the sterlet Acipenser ruthenus were recorded for the first time in the Vistula Lagoon in 2011. Among 66 sturgeons collected between April and December 2011, the Siberian sturgeon was the most numerous species (77%); however, a significant seasonal variability was observed, with sterlet dominating in the catches in late autumn of the same year. The stomach ...

Abstract:
... We studied the morphological structure of dorsal scutes in adult individuals of Acipenser ruthenus. We determined the morphometric indices of scutes, the values of which are different in males and females. We created a system for sex identification in sterlets based on indices and criteria indicative of the shape of the first five scutes. The results can be used for developing a method for intravi ...
