Abstract
The synthetic steroid l7o-Methyltestosteron (MT) is commonly used as a fbecl aclditive to procluce male population of Nile tilapia (Oreochromis ruiloticus). The use of synthetic testosterone hoimone is not recommended in lndonesia. This study was conducted to evaluate the effect of natural testosterone hormole in bull testes meal (BTM) on the rnasculinization of Nile tilapia using validated aceto carmine squash metho6 *f gonads of the fish. Experimental design was utilized two factors experiments i1 cornplet-ely ranciomizectr design. Fry kept in 40-L glass aquaria at a densify of 40 frylaquarium. Fry (7 dph) receivecl the tsTj\backslash,4 for '7 days(Tl), 14days(T2)and2ldays (T3)anddoses0oz (D1),3%(D2),6%'(D3),and g%(D4). When treatment was these results, indicated that significant (P20.05) masculinization occuffed only in the group treated of BTM and no treated of BTM. In the group treated of BTM, doses and duration treatment is not significant. The percentage of male fish 83.3% (9o/o-7d, 90 -21d, 6%-2ld: doses and duration, respectively), higher than all group. Survival rate of fry (95-99.5%) is not affected by treatment BTM (no significant P>0.05). Fish growth was significantly affected by treatment BTM with no treated of BTM. The highest growth performance of fiy were obtained with the 9%BTM.
