    Cryopreservation of rainbow trout Oncorhynchus mykiss spermatozoa: Effects of extender supplemented with different antioxidants on sperm motility, velocity and fertility

    Kutluyer, Filiz; Kayim, Murathan; Ögretmen, Fatih; Büyükleblebici, Serhat; Tuncer, P. Barbaros

    In present study, it was examined whether addition of different antioxidants to the cryopreservation extenders had an effect on semen post-thaw fertility and motility in rainbow trout (Oncorhynchus mykiss) and also it was investigated the sperm characteristics post-thaw sperm characteristics and fertility. The collected semen was pooled to minimize individual variation. Each pooled ejaculate was split into 12 equal aliquots and diluted with base extenders supplemented with the antioxidants, and a base extender with no additives (control). The pooled semen samples diluted at the ratio of 1:10 by the extenders were subjected to cryopreservation. Antioxidants were separately added to the extenders (one per experimental group): catalase (250 U/l), superoxide dismutase (250 U/l), peroxidase (250 U/l), oxidized glutathione (1.5 mmol/l), reduced glutathione (1.5 mmol/l), L-methionine (1.5 mmol/l), uric acid (0.25 mmol/l), L-ascorbic acid (0.5 mmol/l), alpha-tocopherol (2.0 mmol/l), beta-carotene (0.5 mmol/l) and camitine (0.5 mmol/l). After dilution the semen was aspirated into 0.25 ml straws, the straws were placed on the tray, frozen for 10 min, and plunged into liquid nitrogen. Our results indicated that the post-thaw motility rate increased in extenders supplemented with uric acid, L-methionine, SOD, L-carnitine, alpha-tocopherol and L-reduced glutathione (p < 0.05). The motility duration of frozen thawed semen increased in extenders supplemented with uric acid, L-methionine, SOD, alpha-tocopherol and L-reduced glutathione (p < 0.05). Fertilization rate and hatching rate of frozen-thawed semen was not affected by the tested antioxidants. Consequently, the tested antioxidants affected the motility parameters and cryopreservation extenders could be supplement with antioxidants. This study suggested usage of antioxidants in the cryopreservation of rainbow trout. (C) 2014 Elsevier Inc. All rights reserved.

    EFFECT OF COPPER OXIDE NANOPARTICLES TO SHEEPSHEAD MINNOW (CYPRINODON VARIEGATUS) AT DIFFERENT SALINITIES

    Ates, M.; Dugo, M. A.; Demir, V.; Arslan, Z.; Tchounwou, P. B.

    Nanotechnologies research has become a significant priority worldwide. Many engineered nano-sized materials have been increasingly used in consumer products. But the adverse effects of these nanoparticles on the environment and organisms have recently drawn much attention. The present study investigated the effects of different concentrations of copper oxide nanoparticles (CuO NPs) on the sheepshead minnow (Cyprinodon variegatus) at different salinity regimes, since it is able to withstand a wide range of salinities. The results indicated that CuO NPs could cause behavioral changes in the fish, such as increased mucus secretion, less general activity and loss of equilibrium. No mortality was observed at the presence of CuO NPs during the experiments. But higher oxidative stress was determined at half strength seawater than seawater exposure medium, which can be associated with the decreasing toxicity of CuO NPs as salinity increases. In addition, Cu contents in the tissues of the fish were significantly higher (p<0.05) in the low salinity. The order of Cu accumulation in the fish's organs was intestine > gills > liver.

    Aksu, Onder; Adiguzel, Ragip; Demir, Veysel; Yildirim, Numan; Danabas, Durali; Seker, Sebahat; Can, Safak Seyhaneyildiz; Ates, Mustafa

    Crayfish (Astacus leptodactylus Eschscholtz, 1823) is the native crayfish species in Turkey. It was exported regularly to Western Europe. In this study, bioaccumulation and temporal trends of some trace elements (arsenic: As, cadmium: Cd, copper: Cu, mercury: Hg, lead: Pb, and zinc: Zn) in edible abdomenmuscle of crayfish from Keban Dam Lake (Elazig, Turkey) were investigated for the 2006-2012 period. Sequence of metal concentration levels was Zn > Cu > Hg > Pb > Cd > As in muscle tissues. The highest concentration of Zn (21.69mg kg(-1)) was detected in 2006, while the lowest (4.35mg kg(-1)) in 2009. In general, it was found that the concentrations of trace elements investigated were lower than the maximum permissible limits of the food regulations of the Ministry of Food, Agriculture, and Livestock (MFAL), the Turkish Food Codex and Commission Regulation (EC). If the crayfish selected for the study are recognized as bioindicators of environmental pollution, then it is possible to conclude that the changes in studied trace elements concentrations in the Keban Dam Lake are being steady.

    Kizak, Volkan; Güsner, Yusuf

    The morphometric and meristic characters of 2 F-2 hybrid striped bass (M. chrysops female x M. saxatilis male x M. chrysops female x M. saxatilis male) from the family Moronidae are described. Two specimens were caught from Kemer Dam Lake. The body of the F-2 hybrid striped bass was elongated, moderately compressed, and scaly. Dorsal surface and sides were silver and black to olive-gray, and the abdomen was white in color. Four or 5 longitudinal broken stripes ran above the lateral line to the caudal fin. The stripes were less visible behind the pectoral fins and below the lateral line. The bodies of the F-2 specimens were deeper than 1/4 the fork length. The 2 dorsal fins were separated entirely. The first dorsal fin had 8-9 spines, and the second dorsal fin had a spine and 13-14 soft rays. The caudal fin was slightly forked. The anal fin had 3 spines with 12-14 soft rays. One tooth patch was present on the anterior of the tongue. According to our results, the fish were F-2 hybrid striped bass offspring of F-1 hybrid striped bass, which can reproduce naturally in Turkey. Morphological criteria showed that the F-2 hybrids tended to resemble white bass (M. chrysops).

    ESTIMATION OF THE POPULATION SIZE OF CAPOETA UMBLA (HECKEL, 1843) IN THE LAKE HAZAR (ELAZIG) BY REMOVAL METHOD

    Yüksel, F.; Alp, A.; Gündüz, F.; Çoban, M. Zulfu; Demirol, F.

    Fish populations in smaller aquatic environments are affected by the fishing pressure at a much faster pace. Often, compensation of this effect either takes a long time or is not possible at all. For the purposes of establishing fishing regulations in these water environments, the removal method is able to provide results quickly and almost accurately. The Lake Hazar, which is the environment of our study, is 8,600 hectares in size, and is a natural lake where Capoeta umbla species is caught commercially using gill nets. In this study, stock size of Capoeta umbla in the Lake Hazar (Elazig) was estimated using removal method. In addition, the power of fishing and the status of fishing yield in the lake were evaluated. In our research, it was determined that seven commercial fishing boats caught 25,721 kg of fish in the lake in a fishing season. CPUE was calculated as 1.55 kg (kg/day/a gill net). As a result of the regression analysis, the amount of stock in the lake was the estimated to be 37,781 kg (+/- 14,001 kg). When cumulative catch was formulated as recommended by Ricker (1975), the population size was estimated to be 38,649 kg (+/- 15,007 kg). As a result of our study, the use of removal method was found to be appropriate for small reservoirs with reduced population density due to strong fishing pressure.

    Turan, Nevin; Gündüz, Bayram; Körkoca, Hanifi; Adigüzel, Ragip; Çolak, Naki; Buldurun, Kenan

    A new chelating ligand, 5,5-dimethyl-2-(2-(3-nitrophenyl)hydrazono)cyclohexane-1,3-dione (L), and four transition metal complexes were synthesized. The ligand and its complexes were characterized by IR, H-1 and C-13-NMR spectra, elemental analyses, magnetic susceptibility, mass spectra, UV-Vis. and thermogravimetry-differential thermal analysis (TGA-DTA). The metal complexes showed different geometric structures. Antibacterial tests of the ligand and complexes were also done. The Zn(II) complexes showed antibacterial activity against Staphylococcus aureus ATCC-25923 at middle level. The optical properties of the ligand and its complexes were extensively investigated by optical measurements. The average transmittance value of the ligand was the highest value, while the average transmittance value of the [CuL2(NO3)(2)]center dot 6H(2)O complex was the lowest value. The optical band gap of the ligand, [(Zn)(2)L(OH)(4)]center dot 2DMF, [ZnL(NO3)(2)(H2O)(2)]center dot 5H(2)O, [CuL2(OAc)]center dot OAc center dot 3.5H(2)O and [CuL2(NO3)(2)]center dot 6H(2)O complexes were calculated and 3.121 eV, 2.180 eV, 1.551 eV, 2.489 eV and 1.556 eV values were found, respectively. The complexes decreased the optical band gap of the ligand. The optical band gap value of the [ZnL(NO3)(2)(H2O)(2)]center dot 5H(2)O complex is the lowest value. The optical band gap value of the ligand is the highest value. The complexes decrease the angle of incidence of the ligand, while complexes increase the angle of refraction of the ligand. The electric susceptibility of the ligand decreases with its complexes.

    Ethnopharmacological relevance: This paper provides significant ethnobotanical information on medicinal plants in the Gecitli Township in the Eastern Anatolia Region. Recording such data calls for urgency this is the first ethnobotanical study in which statistical calculations about plants are carried out by means of the FIC method in Eastern (Hakkari) part of Turkey. Aim of the study This study aims to identify the wild plants collected for medicinal purposes by locals of Gecitli which is located in the Eastern Anatolia Region of Turkey, and to identify the uses and local names of these wild plants. Materials and methods: A field study had been carried out for a period of approximately 2 years (20082010). During this period, 70 plants taxa and one mushroom were collected. Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. The plant taxa were collected within the scope of the study; and herbarium materials were prepared. In addition, the relative significance value of the taxa was determined, and informant consensus factor (FIC) was calculated for the medicinal plants included in the study. Results: We have found out in the literature review of the plants included in our study that 70 plant taxa and one mushroom are already used for medicinal purposes while 11 plants are not available among the records in the literature. The most common families are Asteraceae, Apiaceae, Lamiaceae, Rosaceae, Euphorbiaceae, Fabaceae, and Malvaceae. We include in our study and report for the first time the medicinal uses of Alchemilla hessii Rothm., Cirsium pubigerum (Desf.) DC. var. spinosum Pet., Diplotaenia cachrydifolia Boiss., Euphorbia macrocarpa Boiss. & Buhse, Galium consanguineum Boiss., Inula helenium L subsp. vanensis Grierson, Johrenia dichotoma DC. subsp. sintenisii Bornm., Pelargonium quercetorum Agnew, Rosa heckeliana Tratt subsp. vanheurckiana (Crep.) O. Nilsson, Salts aegyptiaca L, Taraxacum montanum (C.A. Mey.) DC. Names of local plants in Turkey vary especially due to vernaculars. The plants that the locals of Gecitli use are called with the same or different local names in various parts of Anatolia. Conclusion: We found out that locals living in the research area use for therapeutic purpose 70 plants taxa and one mushroom which belong to 28 families. Turkish citizens with different ethnic backgrounds took the questionnaire. These people use these wild plants in treatment of several diseases. Comparison of the data obtained in this study with the experimental data obtained in the previous laboratory studies on the wild plants which grow in Gecitli proved ethnobotanical usages to a great extent. Literature review indicated that the therapeutic plants that grow in Gecitli are used in different parts of the world for the treatment of similar diseases. (C) 2014 Elsevier Ireland Ltd.

    Dereli, Zeynep; Sevik, Ramazan; Batu, Ali; Gök, Veli

    Turkish delight is a sugar-based jellylike confection that has been produced for hundreds of years. In this study, four different modified atmospheres were created in order to extend the shelf life of Turkish delight. Microbiological analyses and sensory evaluations were conducted at the beginning of storage and at 7-day intervals thereafter. Microbiological analyses showed that the numbers of total mesophilic aerobic bacteria within samples stored in a modified atmosphere of 30% CO2 plus 70% N-2 were lower than in the other modified atmospheres. According to sensory evaluations, the samples kept in a modified atmosphere of 50% CO2 plus 50% N-2 were unacceptable after the 21st day of storage, whereas those kept in modified atmospheres of both 25% CO2 plus 75% N-2 and 30% CO2 plus 70% N-2 were found to be acceptable even after 30 days of storage.

    THE EFFECTS HYDROXYUREA DERIVATIVE SCHIFF BASES ON FATTY ACIDS AND LYPOPHILIC VITAMINS IN LIVER OF RATS

    Turkoglu, Semra; Parlak, Akif E.; Yildirim, Isil; Karagozoglu, Yusuf; Alayunt, Naci O.

    Schiff bases and their metal complexes have antiviral, antimicrobial, antitumoral, radical scavenging and antioxidant activities. In this study, effects of Schiff base ligand and its metal complexes on the fatty acids and lyphophlilic vitamins of the liver of rats were investigated. The fatty acids of the liver were determined by GC and lyphophlilic vitamins of the liver determined by HPLC. The amounts of stearic acid (18:0), oleic acid (18:1) and monounsaturated fatty acids (MUFA) considerably decreased in the Mn, Ni and Zn complexes groups, whereas the amount of linolenic acid (18:3) and eicosatrienoic acid (20:3) considerably increased in the Ni an Zn complexes groups compared to the control group (P<0.01). However, there was no significant difference (P>0.05) in the amounts of arachidonic acid (20:4), docosahexaenoic acid (22:6), total saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA), total omega-3 and omega-6 fatty acids between groups. The amounts of vitamin K-1, vitamin D-2 considerably increased (P<0.05) in the Mn and Ni complexes groups as compared to the control. It was observed that the amount of a-tocopherol increased both in the Ni and Co complexes groups when compared to the control group but this increase was parallel to the amount in the same groups (P<0.05). As a result, it can be think that with the application of toxic metals such as manganese, cupper, nickel, cobalt, and zinc unsaturated fatty acids affected the activities of enzymes which are in the liver tissue and in charge in the fatty acid chain elongation.

    The probiotics are very important for aquaculture because of their role in enhancing the fish health status, improving disease resistance, growth performance, and body composition, reducing malformations, improving gut morphology and the overall microbial balance. The objective of the presently reported study was to investigate effects of kefir as a probiotic product on the digestive and hepatic enzyme activities, as well as glucose level of Coruh trout, Salmo coruhensis Turan, Kottelat et Engin, 2010. The experiment was performed with four treatments: control group (no kefir), D1, D2, and D3 (kefir-supplemented diet: 10, 20, and 40 g . kg(-1) fish body mass, respectively). The activity of: alanine aminotransferase (ALT), aspartate aminotranferase (AST), lactate dehydrogenase (LDH), lipase, amylase-as well as the glucose levels were determined after 4 months. The results indicated that glucose levels (P < 0.05) and digestive enzymes (lipase and amylase) in the blood serum decreased in fish fed diets containing kefir (P > 0.05). On the contrary, the activity of liver enzymes (ALT, AST, and LDH) increased insignificantly (P > 0.05). In conclusion, digestive and liver enzyme activities were affected by quantitative changes in dietary kefir insignificantly but further research is needed to establish whether the liver and digestive enzyme physiology of Coruh trout can be affected by kefir-supplemented diets in a long-term trial.

    Automatic recognition system of underlying causes of power quality disturbances based on S-Transform and Extreme Learning Machine

    Eristi, Huseyin; Yildirim, Ozal; Eristi, Belkis; Demir, Yakup

    In this paper, a new S-Transform and Extreme Learning Machine (ST-ELM)-based event recognition approach for the purpose of classifying power quality (PQ) event signals automatically has been proposed. In this approach, the distinctive features of the PQ event signals have been obtained with the S-Transform-based feature extraction. The feature vector obtained with feature extraction has been applied as input to the ELM classifier. Ten different classification procedures were determined within the framework of this study to assess the performance of the ELM classifier on PQ event data. Real PQ event data and synthetic PQ event data obtained from MATIAB/Simulink environment have been used in these procedures. Also, three different PQ event data sets, which are formed by adding noises of 20, 30 and 50 dB to the synthetic PQ event data respectively, have been used in order to assess the performance of the proposed approach on noisy conditions. According to the results of performance evaluations, the proposed ST-ELM-based PQ event recognition system has a very high performance of recognizing PQ event data. Besides, classification of noisy data showed that the proposed approach is robust at recognizing noisy data. The performance of the ST-ELM-based recognition system on PQ data shows that this approach has an effective recognition structure that can be used in real power systems. (C) 2014 Elsevier Ltd.
