Abstract The anesthetic efficacy of Valerian ( Valeriana officinalis ) powders was evaluated on common carp Cyprinus carpio L.) following concentrations (250, 350, 450) mg/liter were used in three replicates. During the experiment, period required for partial and total anesthesia time recovery tested, as well number red white blood cells after before Anesthesia addition to serum enzymes represe...

This study was conducted to determine the effect of direct transportation common carp (Cyprinus carpio) fingerlings salt solution 4, 6, 8 and 12 g / L concentrations from a control 2.2 on growth nutrition. The high mortality 100 % occurs during first 24 hours at respectively. No fish occurred treatment 4 6 same period. Statistical analysis final weight, weight increase, daily rate, specific rat...

The aim of this study was to evaluate pharmacokinetic profiles of florfenicol after a single dose of intravenous (5.00 mg kg-1 body weight) and oral (40.00 mg kg-1 body weight) administrations in common carp (Cyprinus carpio). The residue depletion of florfenicol was also investigated after oral administration (10.00 mg kg-1 body weight) and bath treatment (5.00 mg L-1) for 10 consecutive days....

Trophont stages of the c~l ia te fish parasite Ichthyophtl~jrius n~ult i f i l i is were Incubated alive in vitro in serum from immune carp Cyprinus carpi0 and subsequently examined immunoh~stoloyically for bound ant~body. Parasites became immobilized in immune serum and were enveloped by gelatinous mucus-llke material. Carp antibody could not be detected bound to cilia membranes (the major sur...

Dispersed cells from sexually immature carp (footlings) pituitaries were exposed to estradiol (E2) or testosterone (T) (both at 3 × 10 –8 M) in the presence of opioid receptor antagonist naltrexone (10–8 or 10–6 M) and/or agonist – morphine (10–8 or 10–6 M). Naltrexone alone at 10–6 M increased the LH level as compared with the control. Morphine (10–8 or 10–6 M), T and E2 had no influence on LH...

Fish personality traits, such as swimming activity, or personality related emergent behavioural properties, such as the degree of space use shown by an individual fish, should affect encounter rates between individual fish and fishing gear. Increased encounters should in turn drive vulnerability to capture by passively operated gears. However, empirical evidence documenting a relationship betwe...

In this investigation, serum steroid hormones such as testosterone (T), 17β-estradiol (E2) and progesterone (P) in 12 female of the migratory population of Common carp (Cyprinus carpio) in southeast of Caspian Sea during a year from May 2011 to May 2012 were studied. The results of present study revealed that changes in levels of steroid hormones, (E2) and (T) were closely correlated to ovarian...

The hematological parameters of the two-year-old carp (Cyprinus carpio) under combined stressed were studied. quantitative and qualitative deviations in blood composition found experimental group against control group. Neutrophilia, monocytosis lymphocytopenia identified as well an increased number young forms erythrocytes background stress factors.

Sedation of fish before handling and transporting can help curtail undue stress that affect their health. This study investigated the effectiveness sodium bicarbonate (NaHCO3) utilised as an anaesthetic agent for common carp (Cyprinus carpio) with average weight 13.5 ± 0.55 g. The experimental were grouped exposed to different concentrations at 0, 40, 45 50 g L–1 NaHCO3 dissolved in water. Fish...
