Osmotic Fragility And Fatty Acid Composition Of Erythrocyte In Mirror Carp (Cyprinus Carpio) Kept At Different Water Temperatures, Olcay Hi̇sar, Şükri̇ye Aras Hi̇sar, Mükerrem Kaya, Telat Yanik

Turkish Journal of Veterinary & Animal Sciences

Osmotic fragility and fatty acid composition in erythrocytes of mirror carp (Cyprinus carpio) kept at 8 °C, 16 °C and 28 °C were determined. Osmotic fragility in erythrocytes (EOF) increased significantly (0.19-0.24%) with the low water temperature. Significant declines in the quantity of saturated fatty acid (44.49-38.40%) and monounsaturated fatty acids (26.30-13.99%), and significant increases in that of polyunsaturated fatty acid (29.21-47.59%) were determined (P < 0.05). It was concluded that low water temperature caused a tolerable stress in mirror carps.


Comparison Of Fatty Acid Profiles Of Different Tissues Of Mature Trout (Salmo Trutta Labrax, Pallas, 1811) Caught From Kazandere Creek In The Çoruh Region, Erzurum, Turkey, N. Mevlüt Aras, H. İbrahi̇m Hali̇loğlu, Özer Ayik, Hasan Yeti̇m Jan 2003

Comparison Of Fatty Acid Profiles Of Different Tissues Of Mature Trout (Salmo Trutta Labrax, Pallas, 1811) Caught From Kazandere Creek In The Çoruh Region, Erzurum, Turkey, N. Mevlüt Aras, H. İbrahi̇m Hali̇loğlu, Özer Ayik, Hasan Yeti̇m

Turkish Journal of Veterinary & Animal Sciences

The fatty acid (FA) composition of some tissues of Salmo trutta labrax, Pallas, 1811 mature native freshwater wild salmon species caught from Kazandere creek in the Çoruh region in Turkey were investigated. Fatty acids profiles of muscle, liver, gonad, egg and adipose tissue were compared in terms of total and individual saturated and unsaturated fatty acids. The results showed that the highest total saturated fatty acid content was in the muscle (37.20 ± 1.13%) while the lowest value was in the egg (27.12 ± 2.53%), and the differences were significant (P < 0.05) among the tissues. Monounsaturated fatty acid contents (MUFA) were not significantly different (P > 0.05) for the tissues but n-3 polyunsaturated fatty acid …

Determination Of Fatty Acid Compositions Of Five Different Tilapia Species From The Çukurova (Adana/Turkey) Region, Mehmet Çeli̇k, Mahmut Ali̇ Gökçe

Turkish Journal of Veterinary & Animal Sciences

The fatty acid compositions of Tilapia rendalli, T. zilli and Oreochromis aurea reared in cages located in Seyhan Dam Lake, O. niloticus reared in freshwater ponds and Tilapia spp. from the Seyhan River were compared. The fatty acid levels of Tilapia spp. from the Seyhan River were significantly higher than those of the other groups (p < 0.05). Total \omega-3 fatty acid values were significantly different for all groups and the highest level were found in Tilapia spp. (p < 0.05). The ratio of \omega-3/ \omega-6 for Tilapia spp., O. aurea, T. rendalli, T. zilli and O. niloticus were 1.95, 1.37, 1.29, 1.21 and 1.12, respectively.


The Effects Of Replacing Fish Oil With Vegetable Oils In Starter Feeds On The Liver Fat Composition Of Sea Bass (Dicentrarchus Labrax L., 1758), Mustafa Yildiz, Erdal Şener Jan 2003

The Effects Of Replacing Fish Oil With Vegetable Oils In Starter Feeds On The Liver Fat Composition Of Sea Bass (Dicentrarchus Labrax L., 1758), Mustafa Yildiz, Erdal Şener

Turkish Journal of Veterinary & Animal Sciences

The effects of replacing fish oil with soybean oil, sunflower oil, corn oil and olive oil in starter feeds on the vicerosomatic index, hepatosomatic index and liver fatty acid composition of the sea bass were studied. Juvenile sea bass (initial weight = 7.58 ± 0.13 g) were fed experimental diets for 75 days. The fish were then killed and liver samples were collected. The lowest total crude fat value (17.61%) was found in the fish fed the fish oil diet. The highest total crude fat value (34.30%) was found in the fish fed the olive oil diet (P < 0.05). Similarly, the fish fed the fish oil diet had the lowest hepatosomatic index value (2.08) and all the fish fed vegetable oils had similarly high hepatosomatic index values (P < 0.05). Likewise, vicerosomatic index values were lowest (9.06%) in the fish fed fish oil and highest in the fish fed soybean and other vegetable oils (P < 0.05). Fatty acid analyses showed that EPA and DHA from n-3 HUFA's in the fish fed the fish oil diet, linolenic acid (18:3n-3) and linoleic acid (18:2n-6) in the fish fed the soybean oil diet and oleic acid (18:1n-9) in the fish fed the olive oil diet were higher than in the fish fed the other diets.

The aim of this research was to compare the fatty acid composition of egg, sperm and diet of 3-year-old brood stock rainbow trout. The results showed that there were statistically significant (P < 0,01) differences between egg, sperm and diet levels in terms of SFA, MUFA, PUFA (n-3, n-6) and EPA/DHA, which are known as important agents for fish nutrition.


Comparison Of The Fatty Acid Composition Of Different Tissues In Mature Trout (Salmo Trutta Macrostigma, Dumeril, 1858) In Yeşildere Creek In The Karasu Basin, N. Mevlüt Aras, H. İbrahi̇m Hali̇loğlu, Abdulkadi̇r Bayir, Muhammed Atamanalp, A. Necdet Si̇rkeci̇oğlu Jan 2003

Comparison Of The Fatty Acid Composition Of Different Tissues In Mature Trout (Salmo Trutta Macrostigma, Dumeril, 1858) In Yeşildere Creek In The Karasu Basin, N. Mevlüt Aras, H. İbrahi̇m Hali̇loğlu, Abdulkadi̇r Bayir, Muhammed Atamanalp, A. Necdet Si̇rkeci̇oğlu

Turkish Journal of Veterinary & Animal Sciences

In this research the fatty acid composition of different tissues of mature trout caught from Yeşildere creek in the Fırat region were investigated. In the adipose, gonad, liver and muscle tissues, the differences among the percentages of monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (n-3, n-6 PUFA) and the eicosapentaenoic acid (EPA)/decosahexaenoic acid (DHA) ratio were statistically significant (P < 0.01). However, the differences in the saturated fatty acids (SFA) of tissues were not distinctive. The most important fatty acids were palmitic (16:0), stearic (18:0) and miristic (14:0) in SFA and 18:1 n-9 and 16:1 n-7 in MUFA. The ratio of n3/n6, known as characteristic agents of marine fish, was as high as in marine fish but the differences among the tissues were not significant.
