“…VTG is subsequently sequestered by the oocytes, processed and stored for the nutrition of the embryo (Nagahama 1987;Persson et al 1998). In fact, there is a positive relationship between VTG concentration and plasma Ca during vitellogenesis stage (Linares-Casenave et al 2003). Similar change trends in the plasma E2 and Ca were identified in our study.…”

“…In fact, there is a positive relationship between Vtg concentration and plasma calcium during vitellogenesis stage. In teleosts, numerous studies showed the positive relationship between plasma calcium and Vtg concentration (Nakari et al 1988;Linares-Casenave et al 2003;Gillespie & Peyster 2004).…”

To identify a simple indicator for detection of follicular vitellogenesis stage of cultured Caspian brown trout, the changes of plasma calcium and estradiol-17β along with ovarian histology were investigated over a reproductive cycle. For this purpose, the blood and gonad samples were taken monthly over a six months period. According to results, the concentrations of plasma calcium increased significantly during October and November but then declined steadily until the end of experiment. Estradiol-17β concentrations were low throughout the experiment, a clear peak was observed in October. Histological observations showed that all examined females were in vitellogenesis when the peak of plasma calcium and estradiol-17β were observed. Also, significant positive relationship was found between plasma calcium and estradiol. The good fitness of plasma calcium and estradiol-17β peak with histological observations suggests that plasma calcium could be a good and simple indicator for detection of follicular vitellogenesis stage in the cultured Caspian brown trout.

“…The phases of the ovarian cycle have been determined histologically and through plasma metabolic profiles [10]. Because of the asynchronous onset of vitellogenesis and its long duration, the maturing stocks will typically have three main ovarian stages if sampled in the fall [25].…”

“…In our previous work, Fourier transform infrared (FT-IR) spectroscopy (4000-400 cm -1 ) was employed to investigate the biochemical composition of sturgeon plasma [6] and the spectral features could be partially related to sturgeon reproductive maturity at different stages [7]. Other research indicates that sex steroids and vitellogenin (VTG) in sturgeon blood plasma serve as suitable biomarkers for predicting sturgeon maturity [8][9][10][11]. Spectra reflect important chemical information in plasma, including proteins, lipids, polysaccharides, nucleic acids, and constituents important for fish reproduction, such as vitellogenin (VTG) and sex steroids.…”

“…The raw FT-IR spectral features of white sturgeon plasma were characterized in earlier studies [6,7]. The relationship between an ovarian histological prediction of sturgeon maturity and the concentration of biochemical compounds in plasma can also be determined [10]. The major focus of this study was to describe the biochemical characterization of sturgeon plasma and caviar.…”

Ovarian maturity of white sturgeon (Acipenser transmontanus, Acipenseridae) farmed in California (Sterling Caviar, LLC) (N=400) and Idaho (Fish Breeders and Blind Canyon Aqua Ranch) (N=143) was determined by correlating blood plasma spectral features [(Fourier transform infrared (FT-IR, 4000-400 cm -1 ) spectroscopy] with oocyte polarization index (PI), an index of germinal vesicle migration. A total of ~20,000 spectra were collected over a period of four years (2007, 2008, 2009 and 2010). Mathematical models could predict maturity in fish at a later year of harvest (i.e., 2010) and at either the California or Idaho production sites. PI values of 0.10, 0.15, and 0.20 were selected for segregating fish into subgroups based on ovarian maturity. Spectral features for specific proteins, lipids, carbohydrates and nucleic acids were related to fish maturity stages. Mathematical models could predict the actual PI values based on plasma spectral features in fish from 2010 based on models developed and validated from fish harvested in [2007][2008][2009]. These models worked equally well whether the fish were raised in California or Idaho. This research indicates that infrared spectroscopy provides a rapid and less invasive method to segregate sturgeon females according to maturity levels and has the potential to substitute for the traditional surgical biopsy to determine stage of maturity.
