“…Our results revealed a dosedependent masculinization effect of dietary A. vera on Nile Tilapia fry, with the highest percentage of males observed at the highest (4.0%) dosage. Similar to our findings, saponin extracts from the soapbark tree (Francis et al 2002;Stadtlander et al 2008), fenugreek (Stadtlander et al 2008), Tribulus terrestris (Omitoyin et al 2013;Ghosal and Chakraborty 2014b;Ghosal et al 2015), and velvet bean Mucuna pruriens incorporated into the diets of Nile Tilapia larvae reportedly shifted the normal 1:1 sex ratio in favor of males, and higher percentages of males were recorded at higher concentrations. Interestingly, red kwao krua Butea superba root extracts (Kiriyakit 2014), moringa (Ampofo-Yeboah 2013), and papaya seeds (Ampofo-Yeboah 2013) in tilapia feed reportedly produced male percentages similar to those obtained by use of a synthetic sexreversal hormone (17α-methyltestosterone).…”

“…Currently, there is inadequate information on the potential use of medicinal plants in generating monosex tilapia populations in production systems. However, Ceylon spinach (Ghosal and Chakraborty 2014a;Ghosal et al 2015), soybean Glycine max (El-Sayed et al 2012), soapbark tree Quillaja saponaria (Francis et al 2002), Tribulus terrestris (Omitoyin et al 2013), and fenugreek (Stadtlander et al 2008) extracts reportedly shifted the sex ratio in favor of male tilapia when administered through diets. Meanwhile, moringa Moringa oleifera (Ampofo-Yeboah 2013), papaya Carica papaya (Abdelhak et al 2013;Ampofo-Yeboah 2013), and Chinese hibiscus Hibiscus rosa-sinensis (Jegede 2010) extracts presented direct effects on gonad morphology and delayed maturation in tilapias.…”

Sex‐Reversal Effect of Dietary Aloe vera (Liliaceae) on Genetically Improved Farmed Nile Tilapia Fry

We evaluated the hypothesis that administering dietary Aloe vera to sexually undifferentiated fry of genetically improved farmed Nile Tilapia Oreochromis niloticus for 30 d would affect their sex ratio. Five experimental treatments were designed, including a control and 100% A. vera powder incorporated into the feed at 0.5, 1.0, 2.0, and 4.0%. After 30 d of feeding, the experimental diets were replaced with a commercial diet, which was administered to the fish for another 42 d to attain the size at which sex determination was possible. Based on logistic regression analysis, an increase in the A. vera inclusion level from 1.0% to 4.0% resulted in a significantly greater percentage of males compared to the control and the 0.5% A. vera inclusion level, with the 4.0% A. vera group presenting potent masculinization effects (67.62% male). However, the survival percentage among fish that received 4.0% A. vera was significantly lower than survival in the other groups. The present results indicate that A. vera extracts have the potential to be used as sex-reversal agents in Nile Tilapia culture, but additional studies are necessary.

“…Similar results were obtained in other studies with Poecilia reticulata and P. latipinna as well where immersion treatment with T. terrestris extract showed no significant difference in survival of fish compared to that of untreated control (Çek et al, 2007b;Kavitha & Subramanian, 2011). Immersion treatment with B. alba leaf aqueous extract resulted in no significant difference in survival of tilapia (Ghosal and Chakraborty 2014). B. alba has been reported to be used in traditional medicine to treat sexual asthenia and infertility in man (Adhikari et al, 2012).…”

The present study was aimed to evaluate the efficacy of Basella alba and Tribulus terrestris for induction of masculinisation in Nile tilpia. B. alba leaves and T. terrestris seeds were extracted with water, ethanol, methanol, dichloromethane, hexane and successive methanol and mixed sex juveniles of Nile tilapia were subjected to dietary treatment with the extracts at the concentration of 0.5, 1.0 and 1.5 gm/kg feed. Treatment with both the plants showed no adverse effect on general fish health. There was no significant interaction effects (P>0.05) of solvent and concentration, and solvent and plant material for percentage of males. But, significant interaction effect (P<0.05) of concentration and plant material was observed for percentage of males. Also, there was significant interaction effect (P<0.05) of solvent, concentration and plant material for percentage of males. For dietary administration of B. alba leaves, the highest percentage of males (83.2±0.7) was obtained by treatment with ethanol extract at the concentration of 1.0 gm/kg feed. For all the solvents, the highest percentage of males was observed at the concentration of 1.0 gm/kg. But, in treatment with T. terrestris seeds, the highest percentage of males (88.9±1.1) was obtained with ethanol extract at the concentration of 1.5 gm/kg feed, which was also the highest percentage of males for all the treatment categories.

“…Despite the effectiveness and safety of this technique, in the last decades' herbal extracts have been proposed for use as active agents to control reproduction in the cultivation of tilapia, in order to find more economically accessible alternatives for aquaculture development (Gabriel et al, 2015). The use of herbal extracts as sex reversal inducers in fish has a variable efficiency percentage, most often no more than 80%, depending on the plant used, concentration of active ingredients, the species studied, and the developmental phase of the organism during application (Ghosal & Chakraborty, 2014;Ghosal et al, 2016). This places the alternative at a disadvantage in comparison to the 97% sex reversal of the conventional method (El-Greisy & El-Gamal, 2012).…”

ABSTRACT. The effect of Passiflora incarnata's extract (PE) on gonadal maturation in young tilapia (Oreochromis sp.) was evaluated by administering feed supplemented with PE during the first 90 days immediately after yolk sac assimilation. One hundred and fifty fishes with 0.01 ± 0.003 g average body weight were randomly distributed in ten tanks with the following duplicated treatments: commercial feed (NAT), NAT with 60 mg kg -1 of 17-MT (MET), and NAT supplemented with 31.10 mg, 62.30 mg and 124.60 mg of PE g -1 (P1, P2, P3 respectively). There were no significant differences (P > 0.05) in the average body weight or in the male-female sex ratio between the experimental treatments (P1, P2, P3) and the control (NAT). Statistical differences in the gonadosomatic index (GSI) and the percentage distribution of gonadal maturation stages (PDGMS) were observed in females of P2 and P3. With respect to the females of NAT, the treatments P2 and P3 presented a lower GSI and a lower percentage of females in stage III (GSI: 1.11 ± 0.88, 1.04 ± 0.99 and 1.71 ± 0.72; PDGMS: 45, 30 and 80%, respectively). No significant differences in GSI or PDGMS were observed in the males. The results suggest that the observed differences in GSI and PDGMS in females are unrelated to antinutritional effects. Instead, these differences could be due to a possible antiestrogenic effect attributed to the possible anti-aromatase action of some of its compounds. Future research focusing on the use of PE for reproductive control in tilapia is suggested.
