Öğe A comparative evaluation of hematological and biochemical parameters between the Italian mullet Mugil cephalus (Linnaeus 1758) and the Turkish mullet Chelon auratus (Risso 1810)(Tubitak Scientific & Technological Research Council Turkey, 2020) Fazio, Francesco; Saoca, Concetta; Acar, Umit; Tezel, Rifat; Celik, Murat; Yılmaz, Sevdan; Kesbic, Osman SabriThis study aimed to carry out a comparative evaluation of the hematological profile (erythrocyte count, hemoglobin concentration, hematocrit, and Wintrobe index parameters such as mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration), in addition to certain biochemical parameters (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, scrum total protein, albumin, glucose, total cholesterol, and triglycerides), in the Italian mullet Mugil cephalus (Linnaeus 1758) and the Turkish mullet Chelon auratus (Risso 1810). Accordingly, two groups of fish were used in this study: 30 flathead grey mullets, M. cephalus, caught in Lake Faro, Italy, and 30 golden grey mullets, C. auratus, caught in the estuarine channel system of Keycegiz-Dalyan, Turkey. Statistical evaluations (unpaired t-test) revealed that there were no significant differences in weight or total length values between the two mullet groups. However, the differences between all the evaluated blood parameters (except alanine aminotransferase) between the Italian and the Turkish mullet were significant (P < 0.0001). The present study demonstrated that there were significant hematological and biochemical differences between the Italian (M. cephalus) and the Turkish (C. auratus) mullet. Our findings also contribute to expanding the knowledge on the hematology and biochemistry of two different species of mullet originating from two different habitats. Since the evaluation of blood parameters represents an essential tool in examining the effects of environmental conditions on fish physiology and, consequently, on fish health status, further research in this field is encouraged and would be very useful.Öğe Comparative study on haematological and biochemical parameters of two wild sparid fish species(Cahiers De Biologie Marine, 2019) Acar, Umit; Saoca, Concetta; Kesbic, Osman Sabri; Yılmaz, Sevdan; Yigit, Murat; Inanan, Burak Evren; Fazio, FrancescoDifferent feeding habits may affect the blood parameters in fish species of the same family, even if they live in the same marine habitat. The aim of this study was to compare some haematological and biochemical parameters of two marine fish species of the same family, the saupe Sarpa salpa (Linnaeus, 1758) and the common two-banded seabream Diplodus vulgaris (Geoffroy Saint-Hilaire, 1817), and to establish the similarities and differences between these species. For this purpose red blood cells (RBC), haemoglobin concentration (Hb), haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), glucose (GLU), triglycerides (TRIG), cholesterol (CHOL), serum total protein (TP), albumin (ALB), globulins (GLO), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were determined for 30 fish from each species. Statistical analysis showed significant differences in some haematological and biochemical (RBC, Hb, Hct, TP, ALB, GLO, AST, ALT, ALP and LDH) parameters between the two species. Lower values of RBC, Hb and Hct were found in S. salpa in comparison with D. vulgaris. These differences could be attributed to the feeding behavior, life style and habitat adaptation of the different fish species of the same family and contribute to knowledge of reference values of blood parameters in Sarpa salpa and Diplodus vulgaris. No significant differences were found in MCV, MCH, MCHC and GLU, TRIG, CHOL.Öğe Effects of Essential Oil Derived from the Bitter Orange (Citrus aurantium) on Growth Performance, Histology and Gene Expression Levels in Common Carp Juveniles (Cyprinus carpio)(MDPI AG, 2021) Acar, Ümit; Kesbic, Osman Sabri; Yılmaz, Sevdan; İnanan, Burak Evren; Zemheri-Navruz, Fahriye; Terzi, Funda; Fazio, Francesco; Parrino, VincenzoThe aim of this study was to detect effects of bitter orange (Citrus aurantium) essential oilcommonly called neroli oil (NO) (0, 0.25, 0.50, 1, and 1.5% referred to as NO0 NO0.25, NO0. 05, NO1 and NO1.5, respectively) on growth performance output and expression levels of some growth-related genes in the muscle tissue and some immune-related genes in the head kidney and pathologicadifferences in digestive system organs of common carp Cyprinus carpio. The NO0.25 group had a large improvement in growth efficiency at the end of the 60-day feeding cycle. Real-time PCR (Bio RAD, USA) system was used to detect variations in gene expression levels. Furthermore, NO supplementation of up to 0.25% in muscle tissue controlled the release of growth hormone (GH) and insulin-like growth factor I (IGF-I). Furthermore, in the NO0.25 treatment category, immune response gene levels TNF-α, IL-8 and IL-1ß increased in head kidney tissue. In the histological examination of the liver and intestine, there were significant differences between fish fed with N1 and N1.5 dietsThis study confirms that dietary supplementation of NO up to 0.25% can improve common carp growth efficiency and increase the expression of genes (GH and IGF-I) related to muscle growthTNF-α, IL-8 and IL-1ß genes related to immune status, and liver and intestine histological status ocommon carp.Öğe EFFECTS OF MONTEREY CYPRESS (CUPRESSUS MACROCARPA HARTW) LEAF ESSENTIAL OIL AS A DIETARY SUPPLEMENT ON GROWTH PERFORMANCE AND HAEMATOLOGICAL AND BIOCHEMICAL PARAMETERS OF COMMON CARP (CYPRINUS CARPIO L.)(Walter De Gruyter Gmbh, 2020) Kesbic, Osman Sabri; Parrino, Vincenzo; Acar, Umit; Yılmaz, Sevdan; Lo Paro, Giuseppe; Fazio, FrancescoCommon carp (Cyprinus carpio) is the most fanned freshwater fish worldwide. In recent years, use of natural products in fish diets has become popular in aquaculture, to improve fish health and growth performance. The present study investigated the effects of essential oil from the leaves of Monterey cypress (Cupressus macrocarpa; CMEO) on growth performance and blood parameters in common carp fingerlings. Identification of 96.1% of the CMEO total volatile components was achieved, with the highest contents for terpinen-4-ol and alpha-pinene, at 22.9% and 47.7%, respectively. After 60 days of feeding of the fingerlings with supplemented diets without CMEO (CMEO 0%) and with CMEO at 0.5%, 0.75% and 1%, the best growth performance was seen for those fish fed with the CMEO 0.5% diet. No significant differences were seen for the haematological parameters and blood cell indices versus CMEO 0%. Serum glucose, triglycerides, cholesterol and glutamic pyruvie transaminase were significantly reduced in the fingerlings fed with the CMEO 0.5% diet versus CMEO 0%. Thus, CMEO oil as a 0.5% dietary supplement can be used to improve the growth performance and health status of the common carp without any adverse effects seen.Öğe Effects of Tomato Paste By-Product Extract on Growth Performance and Blood Parameters in Common Carp (Cyprinus carpio)(Mdpi, 2022) Kesbic, Osman Sabri; Acar, Umit; Hassaan, Mohamed Shaban; Yılmaz, Sevdan; Guerrera, Maria Cristina; Fazio, FrancescoSimple Summary The purpose of this research is to evaluate the effects of a tomato paste by-product extract as a dietary supplement for common carp (Cyprinus carpio). At the end of a feeding trial, fish fed with experimental diets showed enhanced growth performance that is key for aquaculture, and a reduced feed conversion ratio, another critical parameter. Hematology parameters such as erythrocyte count (RBC), hemoglobin content (Hb), and hematocrit (Hct) increased in fish feed with the enriched diet. Additionally, blood glucose, cholesterol, and triglyceride levels in common carp fed diets supplemented with tomato paste by-product extract reduced while total protein, albumin, and globulin levels increased. In conclusion, tomato paste by-product extract has the potential to be utilized as a feed additive in aquaculture feeds to enhance health status monitored by blood parameters and stimulating the growth parameters of common carp. This research examined different growth performances and blood parameters of common carp (Cyprinus carpio) consuming diets supplemented with tomato paste by-product extract (TPE). Five diets with different concentrations of TPEs, 0% (TPE0) 0.5% (TPE0.5), 1% (TPE1), 2% (TPE2), and 5% (TPE5) were supplied to 300 common carp (8.38 +/- 0.18 g) (60 fish per group) each day during the 60-day feeding trial. The relative and specific growth rates of fish-fed supplemental diets increased significantly, while the feed conversion ratio significantly decreased (p < 0.05). TPE considerably increased the erythrocyte count (RBC), hemoglobin content (Hb), and hematocrit (Hct) (p < 0.05), according to hematological analyses of blood samples collected after the feeding experiment. The blood biochemical findings indicate that using 1% or more extracts considerably reduced the serum glucose, cholesterol, and triglyceride ratios while significantly increasing the total protein, albumin, and globulin ratios in common carp (p < 0.05). Based on the findings of the study, it was concluded that the 2% extract generated from tomato paste by-products in common carp diets could be utilized as a growth-promoting product without any negative effects on blood parameters linked to feeding in carp.
