Masculinization of the gynogenetic juvenile ship sturgeon (Acipenser nudiventrisLovetsky, 1828) using 17α‐methyl testosterone

Abstract: In sturgeons, the induction of gynogenesis and sex reversal could be important for potential production of neomale sturgeon and all‐female progeny for caviar production. The aim of this study was sex reversal of ship sturgeon (Acipenser nudiventris Lovetsky, 1828) gynogen into male sex. Five‐month‐old gynogens were sex reversed into male by including 17α‐methyl testosterone in their food for 7 months. Three treatments were considered as follows: (a) without treated (gynogen control), (b) 10 mg MT/kg diet, and … Show more

“…Intersex individuals occur in wild and cultured sturgeon popula-tions [16][17][18] and, occasionally, in paddlefish [19]. Intersex individuals have been described in situations of exposure to exogenous sex hormones [17,20,21]; however, it is unclear if these compounds exist in sufficiently high concentrations in the systems that we sampled to cause sex reversal. Sexing errors using the ALLWSex2 marker in lake sturgeon, though small, cannot be considered nonexistent and appear to be biased towards erroneously classifying females as males.…”

“…Additional information on intersex fish and sex determination would benefit aquaculture activities. Based on the conservation value of sturgeons as imperilled with simultaneous commercial value as a source of caviar (Williamson, 2003), much ongoing research is related to artificial and environmental cues for sex determination in captive and wild stocks (Hassanzadeh et al ., 2019; Keyvanshokooh and Gharaei, 2010; Muller et al ., 2018; Webb and Doroshov, 2011). In paddlefish aquaculture, chromosomal manipulation to produce females (for caviar production) has been successful using external and chemical stimuli (Mims and Shelton, 1998; Shelton et al ., 2019).…”

“…Since this review, the number of species and families in which MT has been tested on has increased. The efficacy of MT on masculinization has also been investigated in the European sea bass Dicentrarchus labrax (Blázquez, Piferrer, Zanuy, Carrillo, & Donaldson, 1995), Japanese flounder Paralichthys olivaceus (Kitano, Takamune, Nagahama, & Abe, 2000), sablefish Anoplopoma fimbria (Luckenbach & Fairgrieve, 2016), mud loach Misgurnus mizolepis (Nam, Noh, & Kim, 1998), ship sturgeon Acipenser nudiventris (Hassanzadeh Saber et al, 2019), and black crappie Pomoxis nigromaculatus (Al‐ablani & Phelps, 1997), among others.…”
