AbstractIn this study, the effect of artemisia (Artemisia annua) leaves extract (ALE) on the immune system, growth performance and antioxidant capacity of common carp (Cyprinus carpio) was investigated. Fish with initial weight (90.32 ± 1.12 g) were fed various levels of ALE (0, 0.5, 1 and 1.5 g/kg) for 8 weeks. The results showed that the growth performance (FW, WG, SGR, PER, and LER) in fish fed 1 g/kg ALE was increased significantly (P<0.05) and the feed conversion ratio (FCR) was improved in fish fed 1 and 1.5 g/kg ALE in comparison to the control group (P<0.05). Skin mucus total protein was higher in fish fed diet containing 0.5 g/kg ALE than the other experimental groups (P<0.05), while the lysozyme, immunoglobulin and protease was increased by increasing of ALE in diets. Respiratory burst activity and serum immune parameters were higher in fish fed 0.5 g/kg ALE than the other treatments (P<0.05). Increasing of catalase (CAT) and decreasing of malondialdehyde (MDA) were observed in fish fed ALE, while glutathione peroxidase (GPx) increased only in fish fed 0.5 g/kg ALE. Hence, it can be concluded that ALE has considerable potential as a natural immunostimulant and growth promotor supplement for the common carp’s aquaculture.

AbstractThis study evaluated the effects of grape seed extract (GSE) on the growth performance, immune response, and disease resistance of common carp (Cyprinus carpio). Fish were distributed in four groups and fed diets with varying levels of GSE at 0, 10, 20, and 30 g/kg for 56 days. The final length in fish fed with 20 and 30 g GSE/kg diet significantly increased in comparison with the control group (P<0.05). The final weight and weight gain of fish fed with GSE were statistically higher than the control diet, while the feed conversion ratio was lower in GSE groups than the control. Hematological parameters did not statistically enhance with GSE supplemented diets (P>0.05). However, fish fed with 30 g GSE/kg diet displayed a higher WBC count significantly than the other group (P<0.05). The serum total protein and globulin in fish fed with 20 g GSE/kg diet significantly increased compared to the control (P<0.05). A similar pattern was noticed in results for serum and mucus lysozyme activity with a significant increase in fish fed with 20 and 30 g GSE/kg diet compared to the control (P<0.05). Total antibody levels in serum and mucus samples were also increased in fish by dietary GSE with maximum levels by 20 and 30 g GSE/kg diet. Besides, mucus protease activity was higher in fish received 20 and 30 g GSE/kg diet with maximum level shown in fish fed with 30 g GSE/kg diet compared to the control group (P<0.05). Meanwhile, all groups showed higher mucus antibacterial activity against Aeromonas hydrophila with the highest activity in 30 g GSE/kg diet in comparison with the control group. The cumulative mortality was 36.67% when fish fed with 30 g GSE/kg diet and challenged with A. hydrophila. However, the mortality rate was 40% and 53.33% in fish fed 20 and 30 g GSE/kg diet, respectively. This study suggests that supplementation of GSE could significantly enhance the growth performance, immune responses, and disease resistance against A. hydrophila in common carp.

Abstract The effects of dietary glutathione on growth performance, skin antioxidant capacity, and immune responses and of juvenile taimen (Hucho taimen) were investigated. The experimental fish had a mean initial weight of 5.36 ± 0.13 g and were fed for eight weeks on diets containing graduated amounts of glutathione (0, 100, 200, 400, and 800 mg kg−1). After the 7 d lipopolysaccharide challenge, the immune parameters of the skin mucus, and antioxidant ability were determined. The treatment groups (400 – 800 mg kg−1) showed a higher survival rate and weight gain rate (P < 0.05). There were higher levels of skin mucus protein, lysozyme activity, and alkaline phosphate activity associated with dietary glutathione supplementation (P < 0.05). Dietary glutathione supplementation improved the minimal inhibitory concentration and antimicrobial activity of the skin mucus (P < 0.05). Fish in the treatment groups showed higher superoxide dismutase, glutathione peroxidase, and catalase activity (P < 0.05), whereas the malondialdehyde content was lower (P < 0.05) than those in the control group. Supplementary glutathione decreased the expression levels of TNF-α, IL1β, IL6, IL8 in the skin and ensured the relatively high expression levels of IκBα after lipopolysaccharide challenge. In conclusion, dietary glutathione (400 – 800 mg kg−1) improved the growth performance, decreased lipopolysaccharide-induced skin inflammatory response, indicating that glutathione has the potential anti-inflammatory effects for preventing inflammation diseases in juvenile taimen.

AbstractThe present study investigated the possible effects of including salt of short chain fatty acid, sodium acetate (SA), on skin mucus immune parameters and immune, antioxidant and growth-related genes expression in common carp. There is a little data available about the effective role of SA on immune, antioxidant and growth related genes expression as well as skin mucus immune parameters. The aim of this study was to analysis the effect of SA intake on these factors using common carp (Cyprinus carpio) as model organism. Two hundred and forty healthy common carp (mean weight = 15 ± 0.9 g) supplied and randomly stocked into 12 fiberglass tanks 200 L (20 fish per tank) assigned to four treatments and triplicates. The study was performed in a completely randomized design. The treatments were feeding carps with experimental diets containing different levels (0.0 [control], 0.5, 1 and 2%) of SA. The skin mucus total immunoglobulin and total protein levels in fish fed 2% SA showed significant increase compared to the control group (P < 0.05). Results showed a significant increase in the GH gene expression in 1 and 2% SA treatments (P < 0.05). The carps were fed with diet content 2% SA showed significantly increase in IGF-1 expression (P < 0.05). The expression of GSTa, and GPX (antioxidant genes) revealed a significant increase in the GSTa (fish fed SA at 1% and 2% levels) and GPX gene expression with fish fed 2% SA (P < 0.05). Supplementation of fish diet with SA induce slight elevation in the intestine of all immune-related genes (TNF-α, IL-1β, IL8 and Lyz) compared to the control group (P > 0.05). However, Lyz gene significantly up-regulated in 1 or 2% SA treatments. These results confirmed beneficial effects of SA as a feed additive in common carp culture.

AbstractThe present study investigated possible effects of dietary malic acid on the expression of immunity, antioxidant and growth related genes expression as well as skin mucus immune parameters in common carp. Common carp (Cyprinus carpio) fingerlings were fed diets supplemented with different levels (0 [control], 0.5%, 1%, 2%) of malic acid (MA) for 60 days. The results revealed highest expression levels of immune-related genes (tnf-alpha, il1b, il8 and lyz) in skin of common carp fed 2% MA (P < 0.05). Regarding 1% MA treatment comparison with control group, significant difference was noticed just in case of lyz (P < 0.05). Evaluation of growth related genes expression revealed no significant difference between treatments (P > 0.05). The study of antioxidant related genes (gsta and gpx) in common carp skin fed with MA, showed significant difference between treated groups and control (P < 0.05). Carps fed with 2% MA had highest alkaline phosphatase activity in skin mucus compared other treated groups and control (P < 0.05). There were no significant difference between 0.5% and 1% and control (P > 0.05). The study of total protein and total immunoglobulin (Ig) in common carp skin musus revealed no alteration following MA treatment (P > 0.05). The present data demonstrated that feeding with MA altered immune and antioxidant genes expression in skin mucus of common carp.

This work was designed to evaluate the influence of mercury chloride on some of biochemical and immunological biomarkers in common cap, Cyprinus carpio. Around of 120 fish were randomly allocated into four groups (30 fish per group) in triplicates as follows; first group act as control group provided with water only without adding HgCl2;  G1, G2 and G3 were exposed to waterborne  HgCl2 at levels of  0.01, 0.05 and 0.1 mg l-1 respectively. After one month exposure to HgCl2, there were significantly decreased (P<0.05) in lymphocyte transformation index and in phagocytic and lysozyme activities. Besides, biochemically, Albumin and globulin content exhibited significantly declined (P<0.05) particularly at higher dose of HgCl2. In contrast, blood glucose value and urea showed significantly increased (P<0.05) especially in G3. On the other hand, variable changes were observed in total count of leucocytes included lymphopenia and neutrophilia in G1 and G2 compared to control.  In conclusion, this investigation indicated that mercury chloride has immune suppressive effects and is extremely toxic to common carp.

This study investigates the effects of two-stage fermented feather meal-soybean meal product (TSFP) on growth performance, blood characteristics, and immunity of finishing pigs. Firstly, feather meal-soybean meal is subjected to aerobic fermentation with Bacillus subtilis var. natto N21, B. subtilis Da2 and Da15, B. amyloliquefaciens Da6, Da16 for two days, and anaerobic fermentation with B. coagulans L12 for three days. Then, the fermented product is air-dried into an end product—TSFP. Eighty hybrid pigs (Duroc x KHAPS) with equal numbers of both sexes are randomly assigned into 3% fish meal, 0%, 2.5%, or 5.0% TSFP groups with five replicates per group. Our results show that the average daily feed intake and feed conversion rate of TSFP groups are significantly better than the other groups at 0–3 weeks (p < 0.05). The 5% TSFP group significantly increased HDL-C in the blood (p < 0.05), and decreased LDL-C and blood urea nitrogen content (p < 0.05). The lipopolysaccharide (LPS) and concanavalin A (ConA) in 5% TSFP group and interferon-γ (IFN-γ) content in 2.5% and 5% TSFP groups are significantly higher than the other groups (p < 0.05). The phagocytic oxygen burst capacity and serum IgA content of the 5% TSFP group are significantly higher than those of the fishmeal group (p < 0.05). The CD3, CD4, and CD4 + CD8 + T cells subsets in 2.5% and 5% TSFP groups are significantly higher than the control group (p < 0.05). In conclusion, TSFP has a positive effect on the growth performance and immunity of finishing pigs with the best performance on 5% TSFP.

Heavy metals are one of the most persistent pollutants in waters, and molecular biomarkers as bioindicators could uncover early warning signals of stress suffered by organisms exposed to these pollutants. This research was conducted to explore the impact of lead contaminant on expression levels of hsp70 gene as well as protein pattern and innate immune indicators of skin mucus in Common carp as a biological model. The fish were exposed to different concentrations of Pb(NO3)2 as a source of lead (0, 7.875, 15.75, and 31.5 mg/L of lead) for 14 days. After the completion of the experiment, the liver and gill tissue plus mucus samples were collected from the fish. Next, the effects of exposure to sublethal doses of lead were investigated on expression levels of hsp70 gene, protein pattern, and innate immune indicators of skin mucus. The results indicated that the expression level of hsp70 gene significantly increased (at 7.5% & 30% LC50) in the liver tissue compared to the control group (P<0.05). The protein pattern of treatment samples was different from that of the control group. Also, in the mucus innate immune parameters, the levels of alkaline phosphatase increased significantly at high concentrations of lead contamination in comparison with the control group (P<0.05). The protein levels first revealed an ascending trend (P<0.05), and then a descending trend (at 30% LC50), though it was not a significant downward trend compared with the control group (P>0.05). The results suggested that these physiological indicators in Cyprinus carpio could be used as molecular and mucosal biomarkers for ecotoxicological studies.
