Abstract

The effects of six levels (0, 5, 10, 15, 20, and 25 ppm) of dietary $17\alpha-Methyltestosterone$ (MT) on sex reversal and growth of Oreochromis aureus (Steindachner) and O. niloticus (L.) were evaluated. Fifteen ppm MT produced $100\%$ male populations in both species. Both MT-treated and untreated O. niloticus grew significantly faster than their O. aureus counterparts (P<0.05).

여섯 가지 농도(0, 5, 10, 15, 20, 30 ppm)의 $17\alpha-Methyltestosterone$ (MT)를 사료에 섞어서 청틸라피아 (Oreochromis aureus)와 나일틸라피아 (O. niloticus)에 30일간 먹여서 성전환율과 성장을 비교한 결과는 다음과 같다. 두 종류 모두 15 pprn의 MT는 $100\%$ 숫컷이 생산되었다. MT를 먹인 것이나 먹이지 않은 나일틸라피아는 청틸라피아보다 빨리 성장하였다(P<0.05)
