The effect of water oxygen saturation on growth and haematological profile of juvenile peled Coregonus peled (Gmelin)

Original language description

The effect of varying oxygen saturation regimes on growth and haematological profiles of peled Coregonus peled was investigated on fish of initial age 90days post hatching. Eighty-five juveniles per group (initial body weight 3.09 +/- 0.80g) were submitted to a 63-day experiment with one of four water saturation regimes: normoxia (NORm, 80%-90%), hypoxia (HYPo, 50%-60%), hyperoxia (HYPe, 150%-160%) and intermittent hyperoxia (iHYPe, 150%-160% - 80%-90%). Survival rate in NORm, HYPe and iHYPe ranged from 96.3 +/- 2.1% to 97.7 +/- 2.7, but survival 87.5 +/- 3.0 was significantly lower in the HYPo group. No differences were observed in feed conversion ratio. The highest final body weight of 18.2 +/- 4.6g and a specific growth rate of 2.81 +/- 0.01%/day were seen in the NORm group. Significant differences were found in haemoglobin concentration with increased saturation. The fish had lower haemoglobin 55.00 +/- 5.72 and 51.35 +/- 10.89g/L in treatments HYPe, iHYPe with compared to the normoxia (64.22 +/- 5.78g/L). Haematocrit was similar in the groups HYPo, NORm and iHYPe (0.55 +/- 0.04, 0.58 +/- 0.05 and 0.54 +/- 0.09) with the exception of HYPe, which was significantly lower (0.48 +/- 0.06). Significantly lower count of erythrocyte was observed in iHYPe group (0.88 +/- 0.20) with compared to the normoxia (1.06 +/- 0.13). The supersaturation level was not associated with effects on growth and survival, and adding oxygen is not recommended for intensive rearing of peled. The results showed normoxia oxygen level to be the most suitable conditions for peled.
