  Author(s): Sauti Kalima*, Jere WL and Alexander Shula Kefi
  
  The current study evaluates the growth performance of mono and mixed sex O. tanganicae under semi concreate pond culture conditions. Monosex O. tanganicae were produced on a 60mgMT/kg (17α Methyl- Testosterone) hormone incorporated diet while the mixed sex was raised on same feed but devoid of the hormone for a period of 28 days. The experiment was replicated three times and in a Complete Randomized Design (CRD). Five hundred fry were stocked in each hapa and fed with commercial Novatek feed containing 45% protein @ 10% of their body weight per day for 30 days. A day after post exposure of the hormone for the monosex, the growth (Length and weight) and SGR was compared among both the groups. The highest mean weight gain of 2.184 ± 0.184 g and SGR 6.506 ± 0.242 was noticed for monosex O. tanganicae. These growth parameters were statistical.. View more»
