Characteristics of haematological parameters for carp culture and koi (Cyprinus carpio Linneaus, 1758) reared in an intensive system.

Abstract

Intensive aquaculture needs accurate advices regarding the detection and control of stress and/or disease conditions in order to ensure the health of fish. The fastest way to detect the manifestation of stress is the evaluation of blood parameters. The scope of this paper was the determination and analyses of the most important parameters of blood: haemoglobin concentration (Hb), haematocrit value (Hct), red blood cel counts (RBCc), as well as the values of erythrocyte constants: mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) for cultured carp (Ineu, Frasinet and Ropsa races) and Japanese koi carp (Cyprinus carpio Linnaeus, 1758), reared under conditions of an intensive system as enclosure type on CCDP Nucet. The haemoglobin concentration (Hb) tacked values between 9.58±1.68, 11.62±2.02 and 11.99±1.50 g/100 ml of blood for the races of cultured carp whereas on ornamental carp the mean level of haemoglobin concentration (Hb) is 6.94±1.6 g/100 ml of blood. The smallest values of MCHC have been noted on Japanese ornamental carp (21.60±3.3gHb/100 ml of erythrocytes) comparatively with 26.82±4.99, 34.33±8.28 and 30.10±3.84 gHb/100 ml of erythrocytes, respectively on carp races. To determine the normale values of haematological parameters on carp, at intensive rearing, it is necesary the continuation of studies that could offer standards for physiological condition and for pathological inquest.
