In this study, the total lipid, total protein and fatty acid compositions of Capoetaangorae were investigated. Total lipid content ratios (as wet weight) were found to be as 1.44% in spring, 6.41% in summer, 4.25% in autumn and 4.29% in winter. Total protein ratios in the muscle of C. angorae also varied from16.55% to19.24% during the year. The major fatty acids in the muscles of both sexes were palmitic, oleic, palmitoleic, eicosapentaenoic and docosahexaenoicacids. The proportions of n3 PUFAs were higher than those of n6 PUFAs through the year. The ratios of total n6 PUFAs to n3 PUFAs in the muscle of C. angorae changed from 0.14 to 0.19 in female and from 0.12 to 0.31 in males, respectively. The levels of EPA+DHA in the muscles of both genders changed from 0.19 to 0.91g/100g wet weight. The results showed that the ratios of total lipid and fatty acids in the muscle of C. angorae significantly varied by the year. Anahtar Kelimeler: Capoeta angorae, yağ asitleri, mevsim, besin değeri.
In this study, after the 30 days of boron exposure, the boron bioaccumulation, the catalase (CAT), carbonic anhydrase (CA) and glucose-6-phosphate dehydrogenase (G6PD) activities and a lipid peroxidation product called malondialdehyde (MDA) levels in different tissues of Cyprinus carpio were investigated. Boron accumulation was performed by Atomic Absorption Spestroscopy and biochemical analysis were performed by spectrophotometric method. Boron amounts of all tissues of the fishes in the aquariums containing 10 mg/L boron were higher than the amounts in control groups. It was determined that CAT and G6PD activities of the skin of the fishes in the aquarium supplemented with boron decreased significantly compared to the control group, but the other tissues were not affected significantly. CA activities of the muscle, liver, gill and brain tissues of the group exposed to 10 mg/L boron water were higher than the control group, while the activity in intestine, eye and skin tissues decreased compared to the control group. MDA levels in the muscle, liver, and gill tissues of the fishes in the boron supplemented aquariums decreased compared to the control group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
