Production of Monosex All-Male Nile Tilapia Using Ethanol Extract of Tribulus terrestris Seeds

The effects of four plant extracts on growth, sex reversal, immunological and haemato‐biochemical parameters in Nile tilapia,Oreochmomis niloticus(Linnaeus, 1758)

“…Male percentage in MT, EB, ET and MA after 120 days were in conformity with the results of our earlier studies where the observation was made immediately after 30 days of treatment (Chakraborty, et al., 2011; Ghosal & Chakraborty, 2020; Ghosal et al., 2015; Mukherjee et al., 2018). In monosex tilapia culture, it is desirable to produce 98%–100% male tilapia (Fuentes‐Silva et al., 2013).…”

“…After completion, the water levels in the ponds were increased to about 1 m. Three‐day‐old mixed‐sex Nile tilapia Oreochromis niloticus (Linnaeus, 1758) juveniles (mean weight 0.025 ± 0.009 g; mean length 12.50 ± 0.12 mm, collected from Fish Hatchery of Government of West Bengal, India) were then released in each pond at a density of 20,000 fish/ha in triplicate for each treatment groups. Extraction solvent and treatment concentration for each of the plant material in this study were selected on the basis of our previous experiments (Ghosal & Chakraborty, 2020; Ghosal et al., 2015; Mukherjee et al., 2018), where Nile tilapia juveniles were fed diets fortified with different concentrations of the plant extracts and the solvent extract and concentration which produced the highest male percentage (>80%) for respective plant material was selected as treatment dosage for the present study. The concentration for MT treatment was also based on our earlier observation (Chakraborty, et al., 2011).…”

“…Dietary supplementation with Aloe vera powder was observed to increase male percentage (Gabriel et al., 2017), and improve growth, feed utilization and haemato‐biochemical parameters (Gabriel, et al., 2015) of genetically improved farmed Nile tilapia. Results from our earlier studies indicated the efficacy of B. alba , T. terrestris , M. pruriens and A. racemosus for production of monosex tilapia and dietary administration of ethanol extract of B. alba leaves (1.0 g/kg), ethanol extract of T. terrestris seeds (2.0 g/kg), methanol extract of M. pruriens seeds (0.2 g/kg) and methanol extract of A. racemosus roots (0.2 g/kg) for 30 days produced more than 80% male tilapia (Ghosal & Chakraborty, 2020; Ghosal et al., 2015; Mukherjee et al., 2018). But no study has been performed to analyse the growth and immune status of monosex tilapia produced through dietary treatment with solvent extracts of those plant materials.…”

Dietary supplementation ofTribulus terrestrisextract improves growth and reproductive performances of the male Nile tilapia (Oreochromis niloticus)

“…In addition, the sex-reversed tilapia shows a better growth performance as compared to normal tilapia, while females have a high fertility, reproducing at a small size and exhibiting high somatic growth at higher densities (Ghosal & Chakraborty, 2017).…”

EFECTO DE Tribulus terrestris EN LA SOBREVIVENCIA E INDUCCIÓN SEXUAL EN TILAPIA

“…reportados por Galindo-Félix, Ochoa-Meza, Moreno-Lugo & Juárez-Moreno (2019) donde se utilizó extracto acuoso de 'Tribulus terrestris', no se presentaron efectos negativos en la sobrevivencia de peces guppy ('Poecilia reticulata'). Lo anterior coincide también, con lo reportado por Ghosal & Chakraborty (2017) donde mencionan que la utilización de polvo y extractos acuosos de semillas y hojas, no presentan efectos adversos en la salud general de los peces como tilapia y algunas especies de ornato de la familia de los Poecilidos.…”
