Use of propofol as an anesthetic and its efficacy on some hematological values of ornamental fish Carassius auratus

The aim of this study was to determine the level of anesthesia attained in Carassius auratus using a propofol bath administration and using values of haematological profile of blood and examinations, to assess the effects of the fish exposure to that anaesthetic. Acute toxicity values of propofol for gold fish were found 96 h LC50 6.353 mg/L, 96 h LC1 2.966 mg/L and 96 h LC99 13.609 mg/L. Time to induce anesthesia in propofol experiment was significantly higher than Clove oil (p < 0.05), but there was no significant difference in recovery time between the experiments. No significant decrease was found in Total RBC, WBC, HCT, MCH, MCV and leukogram indices (p > 0.05). MCHC (%) level of propofol experiment (13.93 +/- 1.36) showed significant (p < 0.05) decrease than Clove oil anesthesia (94.95 +/- 24.50) and control (62.46 +/- 21.90). Hb(g/dl) content (5.20 +/- 0.73) showed decrease in propofol exposure compared with control (15.41 +/- 4.76) and clove oil experiment (25.39 +/- 5.73) (p < 0.05).
