AB  - Growth  of  17α-methyltestosterone  treated monosex Nile  tilapia, Oreochromis  niloticus was  compared with  hormone   untreated mixed-sex  fish  in  four different  culture  systems. The  experiment had 2 X 4  factorial design:  the  first  factor was   presence  or  absence of  hormone  treatment  (monosex  and mixed-sex  fish),  the  second  factor was  related  to  culture  system   (cistern, flow-through, pen and pond). Fish were cultured under similar  feeding regime and stocking density  for six months   and  different  growth  parameters  such  as  body  weight,  length,  daily  weight  gain  (DWG),  specific  growth  rate  (SGR),   proximate body composition and  survival  rate were analyzed. Monosex  tilapia showed significantly higher  (P-value  < 0.05)   weight,  length, DWG, SGR  and protein  content  than mixed-sex  fish. Fish  in Pond  culture  showed  significantly higher  (P-  value  < 0.05) weight, DWG and protein content than fish in other 3 culture systems. Survival was not significantly different   (P>0.05) among mixed-sex and monosex fish and between different culture systems. Monosex tilapia in pond culture system   showed  the highest weight, DWG  and protein content while mixed-sex  tilapia  in cistern culture  system  showed  the  lowest   weight, DWG and protein content. Considering the results of this study, culture of monosex tilapia in earthen ponds might be   considered the ideal method for tilapia culture in India.
