Objective:To examine sex reversal both by oral and by immersion using 17α-methyltestosterone on the methyltestosterone residual concentration and the organ histopathology of tilapia ***:This study used oral and immersion treatment methods for sex reversal of tilapia fish and used normal fish as the control and each treatment was repeated 4 times.17α-methyltestosterone at dosages of 60 mg/kg feed and 0.5 mg/L were used for oral and immersion methods,*** the first step,tilapia fry were reared at 100 L aquaria,with a density of 1 fish/L for 2 *** the next step,male tilapias were reared at happa(net cage)of(2×1×1)m3 size in the controlled pond,with a density of 30 fish/happa for 3 *** methyltestosterone residual concentrations were analyzed by one-way analysis of variance and Duncan's multiple range tests,while organ histopathology was analyzed by descriptive ***:Residual concentrations in the serum of methyltestosterone-treated fish were significantly lower than that in normal fish,especially in 4-and 5-month-old tilapias with averages of less than 5μg/L,while in normal fish was more than 5μg/*** the flesh,methyltestosterone residual concentrations showed relatively no significant differences between the oral and immersion treatment groups and methyltestosterone-treated fish remained lower compared to normal fish,except in 5-month-old ***-treated tilapia exhibited histopathological changes on gill,liver,kidneys,and intestine ***:Sex reversal either by oral or by immersion has methyltestosterone residual concentration,but does not exceed the limits(5μg/L or 5μg/kg)of synthetic steroid on the fish body,although methyltestosterone causes histopathological changes on gill,liver,kidneys,and intestine.
