AN ALTERNATIVE SPECIES FOR TRADITIONAL CARP POLYCULTURE IN TURKEY: INITIAL GROWING PERIOD
C. Kaya GÖKÇEK
Himri Barbel fry (Barbus luteus, Heckel 1843) were introduced to traditional carp polyculture under controlled indoor laboratory conditions. Five treatment groups were designed according to different stocking proportions of carp and himri and each treatment were triplicated. The study was carried out for 90 days by using 100-L aquariums and fish were fed three times a day by commercial carp diet. Five stocking treatments were as follow: S1 (100% common carp), S2 (75% common carp+25% himri barbel), S3 (50% common carp+50% himri barbel), S4 (25% common carp+75% himri barbel), and S5 (100% himri barbel). Polyculturing with carp had no adverse effects on himri stocks and vice versa.
