The effect of letrozole, a nonsteroid aromatase inhibitor in combination with steroid hormones 17a-methyl testosterone (as
compared 0.5 to 1 mg/kg/BW) on sex inversion in protogynous orange-spotted grouper,
, was investigated.
Sex change in order to make a total of 6 fish (control and treated with hormone therapy) were considered. The trial in the spring of
1391 on Fisheries Development Center Caps Kolahi (Hormozgan) took place. And in three times 0, 15 and 30 to measured blood
biochemical parameters (cholesterol, glucose, protein, calcium) and steroids (sex 17?-estradiol (E2), testosterone (T) and 11 -
Ketotestosterone (11KT) as gonadal tissue for histological studies using catheter through the vagina gonadal tissue samples were
obtained. The results showed that aromatase inhibitors work well in combination with sex steroid hormones are sex changing.
And a change in the male gonadal tissue was treated well in fish. Also a significant increase in the levels of sex steroids T and
11KT in the treatment by capsule after 30 days. Biochemical parameters were observed with the calcium transport in male-phase
fish has declined while that of protein, cholesterol, and glucose showed an increase after the sex change. In general we can say
that blood metabolic parameters (Ca, Glo, CH) plus the sex steroids (T and 11KT) by changing the gender of the fish increased.
