Sex reversal in red tilapia (Oreochromis spp) fry by immersion technique
Author(s): Ekta Singh, VP Saini and OP Sharma
Abstract: In immersion technique, three doses of 17α-methyltestosterone (MT) (100, 300 and 400 µg/l) were applied for four different exposure durations (i.e 3, 6, 9 and 12 hrs). It is clear from the obtained data that the immersion of O. niloticus fry in 17α-methyltestosterone (MT) at 300μg/liter for 12 hours resulted in the highest percentage of male population (90.00%) showing that exposure time has significant impact (P<0.01). Similarly, other doses were also significant at 5% level of probability. However, the interaction of hormone doses and immersion time were statistically non significant.
