Masculinization of Nile Tilapia (Oreochromis niloticus) through Immersion in 17α- Methyltestosterone or 17α-Methyldihydrotestosterone
One of the most common techniques for producing mono-sex populations is steroid-induced sex inversion. This involves the administration of synthetic androgens (to produce male populations) or estrogens (to produce female populations). Several methods of steroid administration are possible, including injection, microencapsulation, feeding of steroid, and immersion of fry in steroid solutions. Th...
متن کاملmasculinization of blue hap (sciaenochromis ahli) treated with 17α-methyltestosterone
the objective of this study was to determine the efficacy of two procedures i.e. feeding and immersion followed by feeding, for masculinizing blue hap. two experiments (experiments i and ii) were conducted. in experiment i, feeding hormonal treatment was applied on post-yolk sac stage fry (10 days after fertilization at 27ºc). dosages of 30mg (group a) and 60mg (group b) of 17α-methyltestostero...
متن کاملSynthesis and chemical reactions of the steroidal hormone 17α-methyltestosterone.
Structural modifications of natural products with complex structures like steroids require great synthetic effort. A review of literature is presented on the chemistry of the steroidal hormone 17α-methyltestosterone that is approved by Food and Drug Administration (FDA) in the United States as an androgen for estrogen-androgen hormone replacement therapy treatment. The analog also offers specia...
متن کاملPopulation structure in Banggai cardinalfish, Pterapogon kauderni, a coral reef species lacking a pelagic larval phase
Previous studies on two reef fish lacking a pelagic larval phase (Acanthochromis polyacanthus and Embiotoca jacksoni) revealed features that may be characteristic of their lifestyle: (1) low levels of gene flow, (2) frequent population bottlenecks, and (3) strong phylogeographic breaks, all within their over 1,000 km coastal geographic ranges. The present study tested the predictive nature of t...
متن کاملGenetic structure in the coral-reef-associated Banggai cardinalfish, Pterapogon kauderni.
In this study, we used 11 polymorphic microsatellite loci to show that oceanic distances as small as 2-5 km are sufficient to produce high levels of population genetic structure (multilocus F(ST) as high as 0.22) in the Banggai cardinalfish (Pterapogon kauderni), a heavily exploited reef fish lacking a pelagic larval dispersal phase. Global F(ST) among all populations, separated by a maximum di...
