Efficacy of tamoxifen on sex reversal of nile tilapia (Oreochromis niloticus) / N. P. Pandit in Journal of Agriculture and Forestry University, Volume 2 (2018)
[article]
Title : Efficacy of tamoxifen on sex reversal of nile tilapia (Oreochromis niloticus) Material Type: printed text Authors: N. P. Pandit, Author ; R, Ranjan, Author ; R. Wagle, Author ; A. K, Yadav, Author ; N. R. Jaishi, Author ; I. Singh Mahato, Author Publication Date: 2018 Article on page: 211-216 p. Languages : English (eng) Keywords: Cytotam 20 non-steroidal aromatase inhibitor masculinization Abstract: The efficacy of tamoxifen, a non-steroidal aromatase inhibitor, for inducing masculinization in
Nile tilapia was assessed. Nine days post hatch tilapia fry were reared in fine meshed nylon hapas,
suspended in a green cemented pond, and fed with tamoxifen (Cytotam 20) @ 150, 200, 250, 300,
350, 500, and 1000 mg/kg diet for 30 and 40 days. In 30 days treatment group, the percentage of male
fed with tamoxifen @ 150, 200, 250, 300, 350, 500 and 1000 mg/kg diet were 67.6±0.5, 72.4±2.7,
84.5±1.8, 87.5±1.4, 89.7±1.0, 90.0±1.3 and 96.7±1.2, respectively, while control group had 50.8±0.9
to 50.9±1.4% males. Although the treatment with tamoxifen in lower concentrations (150-500 mg/
kg diet) significantly increased the male proportion compared to control diet, the percentage of male
was significantly highest in treatment with 1000 mg/kg diet. There were no significant differences
in percentage of male between 30 and 40 days of treatment durations. Likewise there was no
significant difference in the survival of Nile tilapia fries among control and treatment groups. The
findings revealed that tamoxifen has potential for production of all-male Nile tilapia. The best dose
of tamoxifen was 1000 mg/kg feed. However, increased dose of tamoxifen should be tested to induce
