Fatty Acids Profile,Atherogenic, Thrombogenic,and Polyene Lipid Indices in Golden Grey Mullet (Liza aurata) and Gold Band Goatfish (Upeneus moluccensis) from Mediterranean Sea

ABSTRACT

The aim of this work was to study the seasonal variations of the proximate compositions, fatty acids contents, and related lipid indices (atherogenic index [AI], thrombogenic index [TI], and polyene index [PI]) of golden grey mullet (Liza aurata) and gold band goatfish (Upeneus moluccensis) caught from the northeastern Mediterranean Sea. Proximate compositions and fatty acid contents of both fish species showed statistically significant seasonal variations (p < 0.05). The lipid contents were highest in autumn and lowest in winter in golden grey mullet and gold band goatfish. The main saturated and unsaturated fatty acids were palmitic acid (C16:0), stearic acid (C18:0), palmiteoleic acid (C16:1n-7), oleic acid (18:1n-9c), arachidonic acid (C20:4n-6), eicosapentaenoic acid (EPA, C20:5n-3), and docosahexaenoic acid (DHA, C22:6n-3). The total polyunsaturated fatty acids in gold band goatfish did not show any differences among the seasons, whereas that in golden grey mullet was highest in winter. Levels of EPA, DHA, and n-3/n-6 ratios, as well as AI, TI, and PI, were significantly changed among seasons. The results show that golden grey mullet and gold band goatfish, which are among the important fish in Turkey and of commercial value, are a good source for human consumption in terms of their nutritional quality.     

Species composition and seasonal-occurrence of spider mites and their predators in sprayed and unsprayed apple orchards in Tokat, Turkey

The species composition and seasonal cycle ofTetranychus urticae Koch (two-spotted spider mite) andEotetranychus uncatus Garman (garman spider mite; the two species were evaluated together),Amphitetranychus viennensis (Zacher) (hawthom red spider nite),Panonychus ulni (Koch) (European red mite),Bryobia rubrioculus (Scheuten) (brown mite) (Acari Tetranychidae),Cenopalpus pulcher Can and Fanz. (flat scarlet mite) (Tenuipalpidae) and their natural enemies (Phytoseiidae and Stigmaeidae family members) were compared in two apple orchards during the years 2000 to 2002 in Tokat, Turkey. One orchard was pesticide-free, and the other was sprayed. Surveys were carried out once a week from April to November and the differences in the dominant species of spider mites and phytoseiid mites between the two orchards were recorded. In the sprayed orchard, the dominant phytophagous mites wereA. vienensis andP. ulmi whereas in the unsprayed orchardE uncatus andC pulcher were abundant. It was found that the predatory mites were able to control spider mites in the unsprayed orchard, but the population level was not adequate to control them in the sprayed orchard, presumably due to the excessive use of pesticides.     

Effects of different finishing systems on carcass traits, fatty acid composition, and beef quality characteristics of young Eastern Anatolian Red bulls

The effects of three finishing systems on carcass composition and other characteristics of meat were studied in 15 young Eastern Anatolian Red bulls in Eastern Turkey. For 93?days, five bulls grazed pasture (P), five grazed the same pasture and were given concentrate supplementation (P + C), and five grazed the same pasture for 93?days, and then for an additional 40?days, they received concentrate in a barn (PF). Carcasses of the P bulls were lighter and leaner than those of the PF animals. Compared with the P carcasses, PF carcasses had a greater percentage of kidney, pelvic, and heart fat (P?相似文献

Characterization ofRhizoctonia solani isolates from potatoes in turkey and screening potato cultivars for resistance to AG-3 isolates

A total of 304Rhizoctonia solani isolates and 60 binucleateRhizoctonia-like fungi were recovered from stems and tubers of infected potato plants over a 2-yr period in northeast Turkey.R. solani isolates were identified to 11 anastomosis groups (AGs): AG-1 (0.66%), AG-2-1 (5.6%), AG-2-2 (0.99%), AG-3 (83.9%), AG-5 (4.6%), AG-6 (0.66%), AG-8 (1.32%), AG-9 (0.33%), AG-10 (1.32%), AG-12 (0.33%), and AG-13 (0.33%). In the greenhouse tests, most of the AG-3 isolates were significantly more virulent than isolates belonging to other AGs on potato cv. Batum. Isolates of other anastomosis groups differed in their virulence. Results indicated that AG-3 is an important pathogen on potatoes grown in the study area. Five of 22 commercial and local potato cultivars evaluated for their reaction toR. solani AG-3 isolates (TP-2) under greenhouse conditions were highly resistant; the remaining cultivars exhibited different levels of susceptibility to the pathogen isolate. http://www.phytoparasitica.org posting July 14, 2005.
