Abstract
: The effects of lidocaine on water quality and some hematological parameters in simulated transportation of the fingerling common carp, was investigated. Dissolved oxygen and ammonia of the control group and 0.01, 0.03 and 0.05 ml/lit lidocaine treated groups were tested at 0 h, 1, 2 h, 3 h, 4 h and 5 h simulated transportation. For the hematological assessment, blood samples were collected from the caudal peduncle of fish in all of the treatments at the beginning and termination of the experiment. The results showed decreased oxygen consumption and ammonia excretion by the fish treated with lidocaine during the experiment. No significant differences in the hematological parameters were found in the levels of RBC, Hb, HCT, MCV, MCH, MCHC and WBC in all the groups (p<0.05).

Abstract
Aims Hematological and biochemical parameters are valuable indicators for monitoring fish health and physiological responses, nutritional status and environmental conditions affecting fish health. In this study, the comparison of hematological indices and some biochemical and hormonal factors of blood serum in male and female sea carp were investigated.
Materials and Methods For this purpose, blood samples were taken from two groups of male and female broodstock with 14 fish from each group.
Findings The results of this study on hematological factors showed that in terms of red blood cell (RBC), hematocrit (HCT), hemoglobin (HB), mean red blood cell volume (MCV), mean concentration of hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), white blood cell (WBC), monocyte (Mo) and granulocyte (Gr), there is no statistically significant difference between the two sexes (P> 0.05). The results of this study showed that there was a statistically significant difference between males and females in terms of glucose, cholesterol, calcium and cortisol (P <0.05). The amount of glucose and cholesterol in males and the amount of calcium and cortisol in females were higher. There is no statistically significant difference between males and females in terms of triglyceride, total protein, albumin, sodium and potassium (P> 0.05).
Conclusion The results of this study show that sex in sea carp during maturity has no effect on the hematological parameters of fish but can affect some biochemical factors in the blood serum of carp such as glucose, cholesterol, calcium and cortisol.
