Comparative growth performance of monosex and mixed sex red tilapia (O. niloticus L.)
2017
In the present study, the growth performance of mono and mixed sex red tilapia was evaluated under controlled conditions. Two groups of red tilapia (Oreochromis niloticus) fry (i.e. monosex and mixed sex) in triplicate were stocked in cemented cisterns (3X3X1 m). One hundred fry were stocked in each tanks and fed with commercial tilapia diet having 28% protein @ 10% of their body weight per day. After a rearing period of 28 days, the growth (Length and weight) and SGR was compared among both the groups. The highest weight gain (1.21±0.009 g), (0.95±0.020 g) and SGR (5.77) was noticed for monosex red tilapia. These growth parameters were statistically significant as compared to mixed sex. Thus on the basis of better growth performance of monosex red tilapia it is recommend to adopt this farming technique for better returns.
