Sažetak
An investigation was carried out in three variants of experimental fish ponds in which different technologies were applied (l - without fertilizing, feeding of carp with cereals; II - fertilizing, feeding of carp with cereals; III - without fertilizing, feeding of carp with pellets containing 20% of protein). Carp was reared under conditions of policulture with total stock density 3250 ind. ha-1 (2500 ind•ha-1 carp 250 ind•ha-1 silver carp, 250 ind•ha-1 bighead and 250 ind•ha-1 grass carp. Average weights of fishes were from 29 to 77 g.
The values of some hematological and biochemical indices of carp were estimated (hematocrit, hemoglobin, MCHC, total protein and total lipids).
The mean value of concentration of hemoglobin was 111,80±18,38 gl-1 (variant I); 121,60±15,86 gl-1 (variant II) and 122,00±15,61 gl-1 (variant III). Hematocrit value was 0,25±0,03 L˙L-1 0,30±0,03 L˙L-1 0,28±0,02 L˙L-1, and MCHC 0,23±0,01 L˙L-1; 0,23±0,01 L˙L-1; 0,25±0,01 L˙L-1 resp.
The concentration of total protein in blood plasma of carp was 27,00±0,32 g˙L-1 (variant 1), 32,00±0,52 g˙L-1 (variant II) and 34,00±1,02 g˙L-1 (variant III). The concentration oftotallipids was 10,1O±0,29 g˙L-1,11,20±1,60 g˙L-1 and 1l,20±1,60 g˙L-1 resp.
The differences between means values of these indices found in carp of different variants were significant (P>0.05) only for values of total protein (table 3) in variant III where carp was fed with protein of animal origin.
