Evaluation of Physical and Biochemical characteristics of farmed common carp (Cyprinus carpio) melt of Khuzestan province in winter season

Some of the important factors such as temperature, ions and osmolarity have important role on the quality of the melt especially motility. Some of the factors such as spermatocrite, concentration and chemical composition were evaluated for examination of common carp melt. The aim of the present study was evaluation of physical and biochemical characteristics of common carp melt of Khuzestan province in Winter season. Melt was collected from 20 adult fishes. Physical and biochemical examinations were performed. The mean volume of melt was 6.6±3.51 ml, spermatocrite was 46.25±12.38 %, total sperm was 11.75±70×1010 and viability was 46.54±18.32 min. the mean total protein was 0.29±0.35, albumin was 0.03±0.02 g/dl, cholestrol was 9.95±8.31 mg/dl, Calcium was 3.82±1.32, Phosphorus was 1.95±0.92, Magnesium was 3.59±1.31 mg/dl, Chloride was 117.55±15.71, Sodium was 73.33±14.15 and Potassium was 27.45±2.51 mmol/l. Based on the results, the positive correlations were observed between weight of fishes with volume and total sperm, volume of melt with total sperm and Sodium, spermatocrit with sperm density, total protein, albumin, cholestrol, P and Na, albumin with cholestrol, P and Cl, Cholestrol with P and Cl, and P with Cl.
