ABSTRACT
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.
