    Influence of Temperature and Parasite Intensity on Egg Production and Hatching of the Monogenean Dactylogyrus extensus
    (Israeli Journal Of Aquaculture-Bamidgeh, 2012) Turgut, Emine
    Dactylogyrus extensus is a species of monogenetic flukes of the family Dactylogyridae that infests cultured as well as wild fish. Understanding its reproductive biology would help control its population. Temperature and parasite intensity influence egg production and larvae hatching. Therefore, we investigated the effect of these parameters on egg production in vivo and in vitro of D. extensus taken from the gills of Cyprinus carpio at 10 degrees C and 17 degrees C, and on larvae hatching at 10 degrees C, 17 degrees C, and 25 degrees C. Temperature significantly effected both egg production and larvae hatching. A significantly greater number of eggs was produced at 17 degrees C than at 10 degrees C, but the hatching rate was higher and more rapid at 25 degrees C. Egg production in vitro was relatively higher than in vivo. Eggs were resistant to cold water and larvae development was inhibited at 2-3 degrees C. However, when the temperature was increased, larvae development commenced and hatching was observed.

    Seasonal Changes and Host Size-Dependent Variation in Diplostomum sp Infection of Some Cyprinid Fish
    (Zoological Soc Pakistan, 2012) Turgut, Emine; Ozgul, Gulistan
    Some Cyprinid fish species including Leuciscus cephalus, Chondrostoma regium, Capoeta tinca, Capoeta capoeta, Barbus plebejus and Cyprinis carpio were monitored for Diplostomum sp. infection during one year period. In general, prevalence and mean abundance of Dtplostomum sp. was higher in L. cephalus, C. tinca, C. capoeta and B. plebejus during autumn and C. regium and C. carpio during spring. Seasonal changes in the mean abundance of Diplostomum sp. was also significantly higher in autumn in L. cephalus, C. tinca, B. plebejus and in spring in C. regium. Parameters of infection of Diplostomum sp. in three size classes of fish were also studied. Mean abundance of Diplostomum sp. was significantly higher in B. plebejus and C. tinca in fish >20.1 and in C. regium in fish >30 cm. Furthermore, potential infection for fish farm located in Almus Dam Lake was also discussed.

    Su Ürünleri Yetiştiriciliğinde Probiyotiklerin Kullanımı
    (Gazi Osmanpaşa Üniversitesi Ziraat Fakültesi Dergisi, 2007) Turgut, Emine; Develi, Nermin; Tırıl, Serap Ustaoğlu
    Su ürünleri yetiştiriciliğinde hastalıklar, üretimi ve ticareti sınırlayan en önemli etken olarak bilinmektedir. Bunun yanında canlılarda antibiyotik lere karşı direncin artması önemli bir problemdir. Bundan dolayı, su ürünleri yetiştiriciliğinde hastalıkların kontrolünde yoğun olarak kullanılan antimikrobiyallere karşı alternatife ihtiyaç duyulmaktadır. Probiyotikler, hastalıkların kontrolünde kullanılan alternatif bir yol olup ve genellikle besin desteği olarak yeme veya suya ilave edilen canlı mikrobiyallerdir. Bu tip maddeler, bağırsak mikroflorasında denge sağlayarak ve konak canlının bağışıklık cevabını geliştirerek canlının sağlığına olumlu etki ederler. Bunun yanında probiyotikler, su kalitesinin iyileştirilmesinde de etkilidirler.
