Antioxidant defence of the actively feeding Oncorhynchus mykiss (Walbaum 1792) larvae in relation to dietary PUFA and vitamin E contents
Zengin, Hatayi; Yilmaz, Okkes (ELSEVIER SCIENCE BV, 2016)Oxidative stress and antioxidant enzyme activities during the feeding periods of Oncorhynchus mykiss larvae maintained under routine fish-farming conditions were studied. This study examined the antioxidant response, ... -
Antioxidant Enzymatic Defences during Embryogenesis of Rainbow Trout Oncorhynchus mykiss (Walbaum 1792)
Zengin, Hatayi; Yilmaz, Okkes; Demir, Ersin; Gokce, Zehra (CENTRAL FISHERIES RESEARCH INST, 2015)In this study antioxidant enzymes activities such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSHpx), glutathione reductase (GR) and glutathione S-transferase (GST) were investigated in unfertilized ... -
Antioxidant Enzyme Activities and Some Biochemical Changes in Rainbow Trout Oncorhynchus mykiss (Walbaum 1792) Yolk-Sac Larvae
Zengin, Hatayi; Yilmaz, Okkes; Gokce, Zehra; Demir, Ersin (CENTRAL FISHERIES RESEARCH INST, 2016)In this work we studied the biochemical status of antioxidant defences of yolk-sac larvae from the commercial fish, rainbow trout Oncorhynchus mykiss (Walbaum 1792) over a period of 19 days from hatching. The parameters ... -
Comparison of Changes in Fatty Acid Composition of Starved and Fed Rainbow Trout, (Oncorhynchus mykiss) Larvae
Zengin, Hatayi; Vural, Nilufer; Celik, Veysel Kenan (CENTRAL FISHERIES RESEARCH INST, 2013)Changes in the fatty acid (FA) composition of unfed and fed rainbow trout (Oncorhynchus mykiss) larvae were determined by gas chromatography. Total lipids were extracted from samples by homogenization in chloroform/methanol ... -
Fatty acid composition of Oncorhynchus mykiss during embryogenesis and other developmental stages
Zengin, Hatayi; Akpinar, Mehmet Ali (SPRINGER, 2006)Fatty acid compositions of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) was determined during embryogenesis, yolk-sac fry, swim up fry and fry stages. Embryonic and yolk-sac development of fertilized eggs were followed ... -
Oxidative stress and antioxidant defenses after starvation in Oncorhynchus mykiss (Walbaum, 1792) larvae reached free swimming stage
Zengin, Hatayi (EGE UNIV, FAC FISHERIES, 2018)Oxidative stress and antioxidant enzyme activities after starvation of Oncorhynchus mykiss larvae were studied. Just after yolk-sac absorption, free-swimming larvae were maintained under starved condition for a period of ...
