The 17α-Methyltestosterone treats carried out in two periods. The Rainbow trout fingerlings (6.43±0.31 g.) were fed 2.5 and 5 mg/kg MT in first period, lasted 92 days. 2.5 mg/kg MT in second period lasted 96 days. Generally in the this study, 17α-MT was treated 2.5 mgMT/kg-diet, throughout 92 days, and 188 days and 5 mgMT/kg-diet, throughout 92 days to rainbow trout. The group of 2.5 mgMT/kg-diet was separate two groups and then one of them was fed with 2.5 mgMT/kg-diet go on in the second period, lasted 96 days. Other group was fed with control food. Normal feed without MT was given to the control fishes. As a consequence of the analysis, it was found out that MT does not cause a change in the crude protein and crude ash (p>0.05), however it increased the values of the crude fat and decreased the value of moisture (p<0.05) of fish-meat. It not effected the fillet efficiency (p>0.05), however it effected percent of internal organ and visceral fat content and HSI (p<0.05). In the fish, treated 2.5 mg MT/kg-diet, throughout 188 days, visceral fat and percent of internal organ were decreased.

İki periyotta gerçekleştirilen bu araştırmanın birinci periyodunda, gökkuşağı alabalığı yavrularına (6,43±0,31 g) 92 gün süreyle 2,5 ve 5 mg/kg-yem oranında 17α-Metiltestosteron (MT) verilmiştir. İkinci periyotta ise 2,5 mg/kg-yem oranında MT verilen grup iki ayrı gruba ayrılarak bu gruplardan birisine 96 gün süreyle daha MT verilmeye devam edilmiş, diğerine ise normal yem verilmiştir. Genel olarak çalışmada; 2,5 mg/kg-yem MT 92 gün ve 188 gün; 5 mg/kg-yem MT ise 92 gün süreyle gökkuşağı alabalığına uygulanmış ve çalışma konusu parametreler üzerine etkileri araştırılmıştır. Kontrol grubu balıklar çalışma süresince MT içermeyen % 42 ham proteinli büyütme yemi ile beslenmişlerdir. Araştırma neticesinde; MT balık etinde, Ham Protein (HP) ve Ham Kül (HK) oranını değiştirmemiş (p>0,05), nem oranını azaltmış, Ham Yağ (HY) oranını ise arttırmıştır (p0,05), iç organ ve iç organlar arası yağ yüzdesini ve Hepatosomatik index (HSI) oranını etkilediği bulunmuştur (p<0,05). Sürekli 2,5 mg/kg-yem MT uygulaması iç organlar arası yağı azaltmış, dolayısıyla iç organ yüzdesini düşürmüştür.
