Changes in serum levels of estradiol-17/J (E2), testosterone (T), 17,20β-dihydroxy-4-pregnen-3-one (17,20β-P) and vitellogenin (VTG), in cultured adult female bester were examined in relation to ovarian development during a 1-year sampling period. Considerable variations in oocyte development were found among fish. Oocytes at previtellogenic stage (≥0–6mm in diameter) generally started to develop concomitantly with the degeneration of the first batch of oocytes. In vitellogenic individuals… Expand
In vitro steroidogenesis by testicular fragments and ovarian follicles in a hybrid sturgeon, Bester
TLDR
It is demonstrated that the failure of spontaneous spermiation or ovulation is not due to the insufficient synthesis of DHP, but mayDue to the lack of availability of precursors. Expand
Ovarian steroidogenesis in white sturgeon (Acipenser transmontanus) during oocyte maturation and induced ovulation.
TLDR
The results from this study combined with the results of Webb et al. (2001b) suggest the potential roles of 11-deoxycortisol, 17,20beta-P, 20beta-S, and P4 as maturation-inducing steroids in sturgeon. Expand
Gonadal Stage and Sex Steroid Correlations in Siberian Sturgeon, Acipenser baeri, Habituated to a Semitropical Environment
TLDR
Stages of gonadal development, in association with plasma concentrations of the sex steroids 17β-estradiol (E2), progesterone (P4), testosterone (T), and 11-KT), were investigated for a single time point during a natural breeding season in 7-yr-old Siberian sturgeon exposed lifelong to a warmwater environment.

Gonadal Steroids: Synthesis, Plasmatic Levels and Biological Activities in Sturgeons
TLDR
It is revealed that C21 steroids are more potent than testosterone and that 11-oxygenated androgens do not induce maturation, and the C21 steroid increases in blood plasma after hormonal induction of spermiation suggesting their participation in the control of sperm maturation and release. Expand
Effects of estradiol-17β implantation on ovarian growth, sex steroid levels and vitellogenin proxies in previtellogenic sturgeon Huso huso.
TLDR
It is concluded that E2 implants do not stimulate ovarian growth, and hence, E1 implants alone are insufficient to reducing the time until onset of sexual maturation in previtellogenic great sturgeon. Expand
In vitro oocyte maturation in a hybrid cultured sturgeon, bester: Changes in the germinal vesicle breakdown and 17,20β-dihydroxy-4-pregnen-3-one production
TLDR
The results indicated again a relevant role for DHP on oocyte maturation in the bester and suggested that GV localization along with in vitro oocytes maturation assay can be used as practical tools for selecting the appropriate individuals in exogenous induced spawning in bester. Expand
The relationships between gonad development and sex steroid levels at different ages in Acipenser schrenckii.
TLDR
Data demonstrated large differences in sex steroid levels among immature Amur sturgeon, and testicular maturation occurred earlier than ovarian maturation. Expand
Evaluation of sturgeon follicle‐stimulating hormone, luteinizing hormone, estradiol, progesterone and testosterone in Acipenser persicus serum to identify fertile broodstock
TLDR
The proposed model provides a reliable method for selecting suitable broodstock fish and shows significant differences in serum P and T levels following pituitary extract injection, although not before that. Expand
Plasma sex steroid hormones of Persian sturgeon Acipenser persicus as influenced by gonad development stages and season.
TLDR
Sex steroids played the considerable role in growth and development of gonad in Persian sturgeon and their concentrations were varied, depending on different stage of Gonad maturity stage and season. Expand
Ovarian development and cycles in cultured Siberian sturgeon, Acipenser baeri
TLDR
Using gonadal biopsy of marked fish, sex was identified and ovarian development in one cohort of cultured Siberian sturgeon over the age interval 8.5-12.5 year was monitored and biennial and triennial cycles were observed. Expand

Testicular development and serum sex steroid profiles during the annual sexual cycle of the male sturgeon hybrid, the bester
TLDR
It is suggested that the time appropriate for induction of final maturation would be from November–December to April when the testes are in the late stage of development. Expand
Morpho-physiological predictors of ovulatory success in white sturgeon, Acipenser transmontanus Richardson
TLDR
Germinal vesicle position and in vitro oocyte maturation response exhibited the closest relationships with ovulation, and can be used as practical predictors of ovulation for hormonally induced spawning of white sturgeon. Expand
Gonadal morphology, enzyme histochemistry and plasma steroid levels during the annual reproductive cycle of male and female brown bullhead catfish, Ictalurus nebulosus Lesueur
TLDR
Significant differences in GSI and plasma steroid levels during the pre-spawning and spawning periods were observed between the two yearly cycles; they may be related to differences in rainfall during these periods. Expand
Estradiol-17 beta production in isolated amago salmon (Oncorhynchus rhodurus) ovarian follicles and its stimulation by gonadotropins.
TLDR
Evidence is provided that gonadotropin directly controls estradiol-17β production in amago salmon follicles, and this work is the first to demonstrate that in vitro gonadotropic activity in oocytes surrounded by follicle layers of amago Salmon is regulated by a single substance. Expand
Involvement of gonadotrophin and steroid hormones in spermiation in the amago salmon, Oncorhynchus rhodurus, and goldfish, Carassius auratus.
TLDR
Findings are consistent with the suggestion that 17 alpha, 20 beta-diOHprog is involved in the process of spermiation in teleosts and suggested that this hormone is a testicular steroidal mediator of gonadotrophin-induced spermation in amago salmon. Expand
The influence of sex steroids in commercial fish meals and fish diets on plasma concentration of estrogens and vitellogenin in cultured Siberian sturgeon Acipenser baeri
TLDR
Plasma sex steroid assays in the Siberian sturgeon Acipenser barri show that plasmatic 17 0-estradiol lcvels are ncvcr significantly different betwccn males and femalcs at various stages of oogenesis and spermatogencsis, which corresponds to the maximum incorporation of vitellogenin. Expand
Identification and preliminary characterization of white sturgeon (Acipenser transmontanus) vitellogenin mRNA.
TLDR
The induction of vitellogenesis by estrogen in sturgeon, which are a primitive teleost, was found to be similar to induction ofviteLLogenesis in amphibians, avians, and other teleosts. Expand
Seasonal variations in sex steroids of female rainbow trout (Salmo gairdneri Richardson)

The present study examines estrogenic effects of dietary soya bean meal and of commercial trout diet on vitellogenesis in sturgeon. Expand
Possibilities of sturgeon culture in Central Europe
TLDR
The hybrid beluga × sterlet is fully fertile and artificial propagation of bester and other sturgeons is possible without difficulties by means of injection of pituitary glands or releasing hormones, and in the field of sturgeon nutrition further investigation is desirable. Expand
