Abstract: This research was conducted in order to investigate the sex reversal effects of
Nigella sativa seed extract on Tilapia. The
Nigella sativa seeds aqueous extract were prepared according to standard method.
Tilapia zilli broodstock were collected and allowed to bred, afterward the frys were immediately collected with a scoop net and randomly assigned into concrete tank to four different treatment groups (0.0 or control, 0.05, 0.1 and 0.15 g/l) in three replicates. Sexes of the tilapia were determined according to the standard method of sex determination. The result shows that the percentage survival rate in controls was similar to those in the treated groups. The highest percentage (86.67%) of sex reversal was observed in the group treated with 0.15g/l
Nigella sativa seed aqueous extract at 0.15g/l concentrations. while the group treated with 0.2g/l concentration had the least percentage of sex reversal (71.67). Qualitative phytochemicals analysis of
Nigella sativa revealed the presence of alkaloids, flavonoids, steroid, tannins and saponins. The results indicates that,
Nigella sativa seed extract could be used as an alternative method to produce all-male tilapia population in an environment-friendly manner through the use of this natural product.
