  Anesthetic Efficiency of 2-Phenoxyethanol on Broodstock of Salmo munzuricus, a New Trout Species Originating from Munzur Stream

  Karataş, Bilal; Basusta, Asiye; Can, Erkan

  Salmo munzuricus Munzur Vadisi Milli Parkı boyunca akan akarsularda yayılım gösteren yeni isimlendirilmiş bir alabalık türüdür. Bu çalışmada, anestetik madde olarak kullanılan 2-fenoksietanolün etkinliği Munzur akarsuyundan yakalanan yerli kahverengi alabalık üzerinde değerlendirilmiştir. Balıklar, 100-200 g (W1), 200-400 g (W2) ve 400-600 g (W3) olmak üzere üç ağırlık sınıfına ayrılmıştır ve çalışma 0.2, 0.3, 0.4 ve 0.5 mL L-1 olmak üzere 4 farklı anestetik konsantrasyonda yürütülmüştür. En kısa indüksiyon zamanı W3 grubunda, en uzun indüksiyon zamanı W1 grubunda bulunmuştur. En kısa anesteziden uyanma süresi W3 grubunda 73.2±3.83 sn sonra ortaya çıkmış ve en uzun uyanma süresi W1 grubunda 136±31.46 sn olarak tespit edilmiştir. W1 grubundaki 2-fenoksietanol konsantrasyonunun artması ile iyileşme süreleri artış göstermiştir. Bununla birlikte, W2 ve W3 gruplarındaki uyanma sürelerinin, W1 grubunda gözlemlenenden genellikle anlamlı derecede daha uzun olduğu belirlenmiştir. Ayrıca balık büyüklüğünün indüksiyon sürelerini ve uyanma sürelerini etkilediği de tespit edilmiştir. Bu çalışmanın sonucu olarak, 2-fenoksietanol için Salmo munzuricus anaçlarında en uygun konsantrasyonlar 100-400 g ağırlık aralığında 0.4 mL L-1, 400-600 g aralığında ise 0.5 mL L-1 olarak belirlenmiştir

  Anesthetic efficiency of 2-phenoxyethanol on broodstock of salmo munzuricus, a new trout species originating from munzur stream; [Munzur akarsuyu orijinli yeni bir alabalık türü olan salmo munzuricus’un anaç bireyleri üzerinde 2-fenoksietanol’ün anestezik etkinliği]

  Can, Erkan; Başusta, Asiye; Karataş, Bilal

  Salmo munzuricus is a newly-named species of trout that spreads through rivers flowing along the Munzur Valley National Park. The efficacy of anaesthetic 2-phenoxyethanol was evaluated in indigenous brown trout in the present study. Fish were divided into three weight classes: 100-200 g (W1), 200-400 g (W2) and 400-600 g (W3) and they were exposed to four concentrations of anaesthetic (0.2, 0.3, 0.4 and 0.5 mL L-1). The lowest induction time was identified in the group W3 while the highest one was in the group W1. The lowest recovery time occurred after 73.2±3.83 sec in the group W3 and the highest one was 136±31.46 sec in the group W1. The recovery times were increased with increasing the concentration of 2-phenoxyethanol in the group W1. However, recovery times in the groups W2 and W3 were significantly longer than observed in W1, generally. Besides, it was indicated that fish size affected induction times and recovery times. As a result of the present study, the most appropriate concentrations were determined as 0.4 mL L-1 at weights of 100-400 g while 0.5 mL L-1 at weights of 400-600 g for 2-phenoxyethanol in Salmo munzuricus broodstock.

  Effects of Milk Thistle (Silybum marianum) Seed Supplementation to High-Calorie Basal Diets of Quails on Egg Production, Egg Quality Traits, Hatchability and Oxidative Stress Parameters

  Erisir, Zeki; Iflazoglu Mutlu, Seda; Simsek, Ulku Gulcihan; Çiftçi, Mehmet; Azman, Mehmet Ali; Benzer, Fulya; Erisir, Mine

  The purpose of this study was to examine the changes to occur in egg production, egg quality traits, hatchability, and oxidative stress parameters of laying quails fed with high calorie diets and effect of milk thistle (Silybum marianum) seed on these changes. A total of 75 45-day-old quails including 60 females and 15 males were used in the study. The quails were divided into 5 groups with three repetitions. 4 females and 1 male were used in each repetition. The groups of the study were arranged as following; control group (C) consuming corn-soybean based basal diet, oil group (SFO) in which 5% sun flower oil was added into basal diet, oil + milk thistle group (SFO+MT) in which 5% sun flower oil + 1% milk thistle seed was added into basal diet, syrup group (CS) in which 10% corn syrup was added into basal diet, and syrup + milk thistle group (CS+MT) in which 10% corn syrup + 1% milk thistle was added into basal diet. Total egg production was found to be significantly higher in SFO and SFO+MT groups of present study (P<0.05). Feed intake, total egg weight and feed conversion were found similar among the groups (P>0.05). The differences among the groups in albumen rate, yolk rate, dried shell rate and shape index were not statistically significant (P>0.05). The best yolk colour was obtained in SFO+MT and CS groups (P<0.01). There were no statistically differences among the groups in hatchability, hatchability of fertile and embrionic mortality (P>0.05), but the difference in examined fertility were statistically significant (P<0.05). Malonyl dialdehyde (MDA) values of blood, liver and heart tissues were similar among the groups of study (P>0.05). MDA level of kidney significantly increased in CS group, however addition of milk thistle seed into diet was reduced MDA level of kidney in CS+MT group (P<0.01). High calorie diets caused changes in antioxidant system in blood and tissues. Consequently, high-calorie basal diets especially addition of SFO improved only egg production and fertility rate. However feeding quails with corn syrup had significantly higher lipid peroxidation in kidney. Supplementation of milk thistle seed into CS group may protect kidney against free radical damage.

  Determination of Volatile Compounds of Sucuk with Different Orange Fiber and Fat Levels

  Yalinkiliç, Baris; Kaban, Guzin; Ertekin, Ozlem; Kaya, Mukerrem

  In this study, the effects of fat (10, 15 and 20%) and orange fiber (0, 2 and 4%) levels on volatile compounds of sucuk (Turkish dry-fermented sausage) were investigated. The volatile compound profile of sucuk samples was analyzed by gas chromatography/mass spectrometry (GC-MS) by using a solid phase microextraction (SPME). 75 volatile compounds were identified in the sucuk samples. The volatile compounds identified were 11 aldehydes, 7 aliphatic hydrocarbons, 2 acids, 10 esters, 1 furan, 5 alcohols, 8 aromatic hydrocarbons, 6 ketones, 6 sulphur compounds, and 19 terpenes. It was determined that the use of orange fiber had significant (P<0.05) effects on a few volatile compounds (allyl methyl sulfide, copaene and caryophyllene). Alpha-thujene was significantly affected by fat level (P<0.05). Fat level also showed very significant effect on p-xylene and allyl methyl sulfide (P<0.01). As result, orange fiber and fat level had no significant effects on volatile profile of sucuk samples.

  Investigation of Yersinia ruckeri Infection in Rainbow Trout (Oncorhynchus mykiss Walbaum 1792) Farms by Polymerase Chain Reaction (PCR) and Bacteriological Culture

  Seker, Engin; Karahan, Murat; Ispir, Unal; Çetinkaya, Burhan; Saglam, Naim; Sarieyyüpoglu, Mustafa

  This study has been carried out to investigate the presence of Yersinia ruckeri, the causative agent of Enteric Red Mouth (ERM) disease, in rainbow trout fish breeding farms located in Elazig and Malatya provinces in Eastern Turkey. For this purpose, bacteriological culture and a specific polymerase chain reaction (PCR) have been compare with examine blood and intestine samples collected from adult and young rainbow trout fish as well as water samples collected from all the farms. Y. ruckeri was isolated and identified from eight of the 17 fish farms giving a proportion of 52.9% at fish farm. The disease was noted in five of the rainbow trout farms located in Elazig and three of the 11 rainbow trout farms located in Malatya. The agent was detected in five of the six young fish breeding farms. The isolation percentages of the causative agent at fish level were calculated as 25.7% (131/510) in adult and 31.7% (19/60) in young fish, giving an overall proportion of 26.3% (150/570). All the isolates have been successfully identified as Y ruckeri by species-specific PCR. No isolation could be made from water samples. It is therefore concluded that Y. ruckeri infection poses a significant threat to the fish farms in the study area and necessary precautions should urgently be taken in order to minimize economical losses due to ERM disease. A specific PCR can be utilized successfully in aquaculture for rapid identification of bacterial agents which will help to prevent spread of infectious diseases and will therefore contribute to the productivity of fishery sector.

  Koluman, Ahmet; Unlu, Teoman; Dikici, Abdullah; Tezel, Atanur; Akcelik, E. Nazan; Burkan, Zeynep T.

  Staphylococcal food poisoning is one of the most prevalent causes of gastroenteritis throughout the world. This study has three steps. In the first step of the study, different food matrices were analyzed for the presence of Staphylococcus aureus. In the second step, types of staphylococcal enterotoxins (SET) from these foods were analyzed. Lastly, antibiotic resistance of S. aureus isolated was determined using conventional and PCR methods. For this purpose, 300 different food samples were evaluated for contamination with S. aureus. From these samples 221 S. aureus strains were isolated. The same strains were evaluated for antibiotic resistance and existence of mecA gene. All strains were at least resistant to 2 antibiotics, but no MRSA strain was detected. Staphylococcal Enterotoxins (SE) were determined with VIDAS and ELISA from the foods of concern. The results of the analysis held with Vidas SET2 showed 72 (24%) of 300 samples and with ELISA these enterotoxins showed difference in distribution.

  Immunostimulating Effect of Levamisole on Spleen and Head-Kidney Leucocytes of Rainbow trout (Oncorhynchus mykiss, Walbaum 1792)

  Seker, Engin; Ispir, Unal; Dörücü, Mustafa

  An in vitro cultivation method for spleen and head kidney organ section were used to investigate the effects of levamisole on the immune response. After 10 days of culture with 10 mu g/ml, 50 mu g/ml and 100 mu g/ml or no levamisole in the culture media, the non specific defense reaction were measured by glass-adherent NBT (nitroblue tetrazolium) positive cells activation and phagocytic activity. Elevation in phagocytic activity was found for 10 mu g/ml and 50 mu g/ml levels of levamisole (P < 0.001), but no differences were found at levels of phagocytic activity in between 100 mu g/ml levamisole groups and control groups (P > 0.05). In the spleen and head kidney leucocytes, increased response to levamisole was shawn for all doses in the glass-adherent NBT positive cells activation.

  Basçinar, Nadir; Kocabas, Mehmet; Sahin, Sebnem Atasaral; Okumus, Ibrahim

  The aims of this study were to determine hatching performance, body and yolk weight at hatching, the growth rate during the yolk absorption and yolk conversion efficiency of Black Sea trout, brook trout and their hybrid larvae, and to compare the relationships between length, total wet weight, dry yolk body weights of alevins and degree-days. The Black Sea trout egg has shorter incubation duration than brook trout and their hybrid. Survival from fertilization to swim-up of brook trout, Black Sea trout, and hybrid were 45.8%, 54.3% and 30.7%, respectively. Length, total wet weight, dry larva weights, and dry yolk weights of brook trout, Black Sea trout and hybrid exhibited a linear relationship with degree-days; dry yolk weight decreased, while length, total wet weight and dry body weight increased with degree-days. The linear regression parameters excluding length slope were significantly different. Length and weight increase as well as growth rates, daily yolk sac consumption and yolk sac efficiency values were calculated as 0.21 mm/day, 0.63 mg/day, 0.30 mg/day, and 0.61 for brook trout; 0.19 mm/day, 0.87 mg/day, 0.60 mg/day, and 0.76 for Black Sea trout, and 0.20 mm/day, 0.45 mg/day, 0.28 mg/day, and 0.46 for hybrid, respectively.

  Basçinar, Nadir; Sahin, Sebnem Atasaral; Kocabas, Mehmet

  The objectives of the present study were to compare growth performance and feed conversion ratios of brook trout (Salvelinus fontinalis) and Black Sea trout (Salmo trutta labrax) in monoculture and duo-culture tank reared conditions. The fish were about 9-month-old hatchery reared brook trout and Black Sea trout with initial weights of 24.18 +/- 0.64 (n=60) and 23.87 +/- 1.11 (n=60) g, respectively. Fish were kept in 0.2 m(3) fiberglass tanks. Nine tanks were used and the fish were equally allotted to 3 groups with tree replicates and fed for 240 days. Each tank contained 20 fish from each species for monoculture and 10+10 fish from each species for duo-culture. At the end of the study, mean live weights of brook trout and Black Sea trout increased to 265.47 +/- 17.25 g and 206.18 +/- 2.95 g in monoculture. 235.53 +/- 10.25 g and 222.47 +/- 1429 g in duo-culture, respectively, and significant differences were found among the groups (P<0.01). The highest and lowest specific growth rates were found in brook trout and Black Sea trout in monoculture (P<0.01), respectively. The highest and lowest final condition factors were calculated in duo-culture for brook trout and in monoculture for Black Sea trout (P<0.01), respectively. The feed conversion ratio (FCR) for Black Sea trout was higher than it was for the other groups (P < 0.01).
