Abstract

Himri Barbel fry, Carasobarbus luteus (Heckel in 1843) were introduced to tilapia duoculture in net cages. Five treatment groups were designed according to different stocking proportions of tilapia and himri and each treatment were triplicated. The study was carried out for 60 days by using 500 L net cages and fish were fed 2 times a day by commercial carp diet. Five stocking treatments were as follow: SI (100% tilapia), S2 (75% tilapia+25% himn barbel), S3 (50% tilapia+50% himri barbel), S4 (25% tilapia+75% himri barbel) and S5 (100% himn barbel). Polycultunng with tilapia had no adverse effects on himri stocks however total biomass at harvest and feed conversion ratio were negatively affected with increasing himri in tilapia stocks. © Medwell Journals, 2011.
