  Age- and Sex-Specific Bioaccumulation of Selected Metals in Freshwater Mussel (Unio elangatulus eucirrus Bourguignat, 1860) Populating from Keban Dam Lake (Elazig, Turkey)

  Danabaş, Durali; Kutluyer, Filiz; Ural, Mesut; Özçelik, Mehtap; Kocabaş, Mehmet

  In aquatic life, environmental chemicals are accumulated by mussels due to their sentinel nature and filter-feeding characteristics. Herein, the present study focused on assessing the concentrations of Cu, Zn, Mg, Mn, Fe, Cd, Pb, Ca, K, and Na levels in freshwater mussels (Unio elangatulus eucirrus) depending on sex and age. For all trace metals, some important differences of bioaccumulations were determined depending on ages and sex. In details, the results indicated that an important age-related accumulation of Mg, Cd, Ca, and K was in females and all trace elements, except Cu, Mg, and K levels in males (p < 0.05). No statistical differences were determined in mean concentrations of Cu, Zn, Mg, and Na. There are statistical differences in Mg, Mn, Fe, and Ca levels between females and males in four aged mussels (p < 0.05). Lead levels were under detectable limits. Overall, metal levels and their toxicity in freshwater mussels should be closely monitored for health of the environment, animals, and humans, since mussels and fish species fed on them are consumed highly in the research region and around.

  Metal bioaccumulation in selected tissues of barb (Barbus sp.) and common carp (Cyprinus carpio, Linnaeus 1758) from the Keban Dam Lake, Turkey

  Danabas, Durali; Kutluyer, Filiz; Ural, Mesut; Kocabaş, Mehmet

  The aquatic life has been negatively influenced by harmful effects of environmental toxic elements, including heavy metals. The elevated concentrations of metals may be harmful for aquatic animals and human health. Herein, the present study deals with assessment of the bioavailability of metals [cadmium (Cd), chrome (Cr), copper (Cu), zinc (Zn), iron (Fe), lead (Pb), manganese (Mn), mercury (Hg), nickel (Ni), and selenium (Se)] in organs such as muscle, gills, liver, kidney, and gonad of the commercially consumed Barbus sp. and Cyprinus carpio (Linnaeus, 1758) collected from Keban Dam Lake, eastern Turkey. The fish were captured from four different stations of Keban Dam Lake. Our results indicated that Fe and Zn concentrations were the highest in all tissues of two fish species while Cd concentrations were the lowest levels. In addition, detected metals accumulated in the muscle of common carp at higher levels compared to Barbus sp. The results from the present study also demonstrated significant variations and considerable differences in the concentrations of all 10 elements between the four stations and different fish tissues. Overall, the concentrations of detected metals in the muscle were many folds higher than the permissible level prescribed by some national and international legislation, which raises health risk concerns.

  THERAPEUTIC EFFECTS OF THYME (THYMUS VULGARIS LINNEAUS) AND FENNEL (FOENICULUM VULGARE MILLER) ESSENTIAL OILS IN INFECTED RAINBOW TROUT, ONCORHYNCHUS MYKISS (WALBAUM)

  Gulec, A. Kucukgul; Kucukgul, A.; Danabas, D.; Ural, M.; Seker, E.; Arslan, A.; Serdar, O.

  The fish (84 +/- 1.02 g mean +/- SEM) were divided into 3 groups (N=15 in each group) as control (CNT), infected with Yersinia ruckeri (INF), and infected and essential oils (+EO). The CNT and INF groups were fed only with commercial fish feed. The +EO group was fed with feeds prepared with the rate of 10 ml herbal essential oils (mixed thyme and fennel) / 100 g feed during 21 days. The liver tissue (0.4 g) of fish was dissected in third day of the experimental period and mRNA transcription levels in liver tissue were determined by Real Time PCR analysis. INF and +EO groups exhibited decreased immunity against the challenging with Y. ruckeri infection (53.57 and 42.85 % mortality, respectively) when compared with CNT group (93.33 %). Gene mRNA transcription levels of tumour necrosis factor alpha (TNF-alpha), interleukin 1 beta (IL-1 beta), inducible nitric oxide synthesis (iNOS), serum amyloid A (SAA), that are responsible during the initiation and continuation of the inflammation increased in 1.86, 2.46, 1.62 and 55.7 fold change, respectively in INF group, whereas mRNA expressions of haptoglobin (Hp) decreased (1.2-fold change) in 3th day of experimental period. The +EO group eliminated the increase in all of the gene expressions.

  Effect of mixed use of thyme and fennel oils on biochemical properties and electrolytes in rainbow trout as a response to Yersinia ruckeri infection

  Gulec, Azime Kucukgul; Danabas, Durali; Ural, Mesut; Seker, Engin; Arslan, Ali; Serdar, Osman

  The aim of study was to compare the effects of supplementation of food with herbal oils (Thymus vulgaris and Foeniculum vulgare) on biochemical properties and electrolytes of rainbow trout infected with Yersinia ruckeri. In total, 120 healthy fish (mean weight 84 +/- 1.02 g) were equally divided into four experimental groups. The experimental study was carried out for one week. The first group was control without supplementation and infection, the second group was infected and without oil supplementation, the third group was supplemented with oils (10 ml.100 g(-1) rates) for one week and infected with Y ruckeri and the last group was oil supplemented without infection. Results indicated that fish fed with dietary supplements showed enhanced bactericidal activity, total protein, albumin, cholesterol, triglyceride and bilirubin compared to the control (P < 0.05). As the value of herbal oils was increased in diets, the plasma glucose level decreased. The levels of K, Na, Ca, and Mg increased whereas Cl values decreased, compared to the control. It can be concluded that diet supplementation with herb oils used in this study can increase disease resistance by increasing levels of some biochemical parameters and electrolytes in rainbow trout to Y ruckeri infection.

  Determination of Metal (Cu, Zn, Se, Cr and Cd) Levels in Tissues of the Cyprinid Fish, Capoeta trutta (Heckel, 1843) from Different Regions of Keban Dam Lake (Euphrates-Turkey)

  Danabas, Durali; Ural, Mesut

  The aim of this study was to evaluate Copper (Cu), Zinc (Zn), Selenium (Se), Chromium (Cr) and Cadmium (Cd) concentrations in liver, muscle, gills and kidney tissues of Capoeta trutta collected from four sites of Keban Dam Lake, Turkey. The highest heavy metal level in all tissues was for Zn, while Cd was the lowest. The lowest heavy metal levels were generally found at Station 4 (Agin) for all tissues (p < 0.05). There were statistically significant differences among stations for Cu, Zn, Cr and Se in gills; for Cu, Zn, Se and Cr in liver and kidney; and Cu, Zn and Cr in muscle (p < 0.05). Cadmium concentrations did not differ between sites for any of the tissues. Turkish Food Codex sets the maximum limits of Zn, Cu and Cd as, 50, 20 and 0.05 mg kg(-1) dry weight, respectively, in the muscle of fish used for human consumption. In our study, the level of Zn was higher than Turkish permissible limits only at Station 3 (Guluskur). Cadmium levels were much higher than permissible limits at three stations [S1 (Pertek), S2 (Kockale) and S3], whereas Cu levels were within permissible limits in all stations.

  Some Heavy Metals Accumulation in Tissues in Capoeta umbla (Heckel, 1843) from Uzuncayir Dam Lake (Tunceli, Turkey)

  Ural, Mesut; Yildirim, Numan; Danabas, Durali; Kaplan, Olcay; Yildirim, Nuran Cikcikoglu; Ozcelik, Mehtap; Kurekci, Eylem Funda

  Concentrations of metals were determined in the gills, liver, kidney, heart and muscle in Capoeta umbla caught from six stations from the Munzur River system. Metal concentrations in the tissues tended to vary significantly among stations (p < 0.05). Liver (Cu, 10.10 +/- A 0.23-23.03 +/- A 9.37 ppm; Zn, 14.67 +/- A 3.01-21.82 +/- A 2.39 ppm; Cd, 18.04 +/- A 4.56-52.69 +/- A 10.65 ppb and Fe, 28.87 +/- A 6.78-115.11 +/- A 34.87 ppm) and kidney (Cu, 1.80 +/- A 0.25-3.70 +/- A 0.62 ppm; Zn, 20.81 +/- A 0.37-29.36 +/- A 0.70 ppm; Cd, 132.06 +/- A 5.29-639.51 +/- A 20.14 ppb and Fe, 24.40 +/- A 1.98-59.39 +/- A 1.97 ppm) tissues showed higher metal concentrations than other tissues. It seems that metal contamination in the river is too high for the health of fish and the people who eat them. The geographical locations of catch, season, nature of diet, and the size of fish used for analyses might lead to different metal concentration in the same fish species.
