Cryopreservation of Nile Tilapia (Oreochromis niloticus) Sperm
Bozkurt, Yusuf; Yavaş, İlker (Intech Europe, 2016)The main aim of this study is to determine the effect of the straw volume (0.25 vs. 0.5 mL) on Nile tilapia sperm quality after cryopreservation. Sperm was frozen according to conventional slow freezing procedure and diluted ... -
Cryoprotective Effect of Vitamin E Supplementation of Different Extenders on Quality and Fertilizing Ability of Frozen-Thawed Brown Trout Sperm
Bozkurt, Yusuf; Yavaş, İlker; Bucak, Mustafa Numan; Kıran, Tuğba Raika; Gül, Aziz (Mary Ann Liebert Inc., 2021)Vitamin E is one of the most powerful antioxidants for prevention of cell damage resulting from cryopreservation, but its efficacy for cryopreserving brown trout sperm is still unclear. In this work, the protective effect ... -
Effect of different cryoprotectants (glycerol, methanol and dimethyl sulfoxide) on post-thaw quality, viability, fertilization ability and DNA damage of cryopreserved nile tilapia (oreochromis niloticus) spermatozoa
Bozkurt, Yusuf; Yavaş, İlker; Bucak, Mustafa Numan; Yeni, Deniz (Cryo Letters, 2019)BACKGROUND: Cryopreservation of sperm from different fish species requires different protocols. Therefore, it is necessary to perform studies to establish reliable procedures for each species. OBJECTIVE: Experiments were ... -
Effect of different straw volumes and thawing rates on post-thaw quality and fertilization ability of cryopreserved common carp (Cyprinus carpio) sperm
Bozkurt, Yusuf; Yavaş, İlker (Journal of Limnology and Freshwater Fisheries Research, 2017)Cryopreservation of sperm cells is an essential process applied for long-term conservation of aquatic genetic resources. The goal of this research was to determine effect different of straw volumes and thawing rates on the ... -
Effect of extender compositions, glycerol levels, and thawing rates on motility and fertility of cryopreserved wild african catfish (Clarias gariepinus) sperm
Bozkurt, Yusuf; Yavaş, İlker (Israeli Journal of Aquaculture - Bamidgeh, 2017)The aim of this study was to determine the effect of different extenders, glycerol levels, and thawing rates on post-thaw sperm motility and fertilization ability of cryopreserved African catfish (Clarias gariepinus) sperm. ... -
Effect of Extender Supplemented With Boron on Post-Thaw Motility, Viability, DNA Damage and Fertilization Ability of Cryopreserved Brown Trout (salmo trutta macrostigma) Spermatozoa
Bozkurt, Yusuf; Yavaş, İlker; Gül, Aziz; Bucak, Mustafa Numan; Yeni, Deniz; Avdatek, Fatih (Cryo Letters, 2019)BACKGROUND: Boron has been considered as an essential nutrient for decreasing lipid peroxidation and improving antioxidant mechanism in different animal species. On the other hand, its effect on quality or DNA damage ... -
Effect of extender supplemented with different sugar types on post-thaw motility, viability and fertilizing ability of cryopreserved common carp (Cyprinus carpio) spermatozoa
Bozkurt, Yusuf; Yavaş, İlker; Yıldız, Cengiz (Israeli Journal of Aquaculture - Bamidgeh, 2016)The influence of various sugar types supplemented to the extender on post-thaw motility, viability, and fertilizing capacity of cryopreserved common carp (Cyprinus carpio) semen were investigated. The results indicated ... -
Effect of supplementations of docosahexaenoic acid (DHA) into a tris-glucose based extender on the post-thaw sperm quality, fertility and hatching rates in brown trout (salmo trutta macrostigma) following cryopreservation
Bozkurt, Yusuf; Yavaş, İlker (Islamic Azad University of Tonekabon, 2021)The supplementation of extenders with PUFAs has not been investigated in fish by now. Thus, the present study examined whether different levels of docosahexaenoic (DHA), which is the predominant PUFAs in the sperm plasma ...
