SOME HEMATOLOGICAL VALUES OF TWO-YEAR OLD CARP (Cyprinus carpio L.)

Abstract

Istraženo je djelovanje različitih tehnologija (I - bez gnojidbe, prihranjivanje riba žitaricama, II - gnojidba, prihranjivanje riba žitaricama i III - bez gnojidbe, prihranjivanje riba briketima s 20% životinjskih proteina) u uzgoju šarana u polikulturi s bijelim i sivim glavašem i bijelim amurom na neke hematološke pokazatelje (hematokrit, koncentracija hemoglobina, srednja koncentracija boje, ukupni proteini i ukupni lipidi). Gustoća je nasada bila 3.250 ind˙ha-1, a od toga šaran s 2.500 ind˙ha-1 (772). Prosječna vrijednost hemoglobina u krvnom serumu šarana bila je u kontrolnoj varijanti I 111,80±18,38 gr1, u varijanti II s gnojidbom mineralnim gnojivom NPK (17: 8: 9) i prihranjivanjem žitaricama 121,60±15,86, a u varijanti III bez gnojidbe i uz prihranjivanje briketima s 20% proteina 122,00±15,61 g˙l-1. Vrijednost je hematokrita iznosila pripadajuće 0,25±O,03, O,30±0,03 i O,28±0,00 L˙L-1, te srednja koncentracija boje 0,23±0,01, 0,23±O,01 i O,25±0,01 L˙L-1. Prosječna količina ukupnih proteina u krvnom serumu šarana iznosila je 27,OO±O,32 (varijanta I), 32,00±0,52 (varijanta II) i 34,00±1,02 (varijanta III). Prosječna vrijednost ukupnih lipida u krvnom serumu šarana bila je 1O,10±O,29 gr1 (varijanta I), 11,20±1,60 g˙l-1 (varijanta II) i l1,20±1,60 g˙l-1 (varijanta III). Statistički opravdane razlike utvrđene su samo u količini ukupnih proteina u serumu šarana (P>0,05), i to u korist varijante III u kojoj je šaran prihranjivan bjelančevinama životinjskog porijekla.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
