“…Therefore we speculate on possible metabolic differences. Early studies on fatty acids in carp were performed by Farkas and Csengeri (1976) and Farkas et al (1978). The observed differences in n-3 PUFA in the fish in our experiment can possibly be ascribed to different fatty acid metabolism, because the lipid content was not significant.…”

Common carp (Cyprinus carpio) is, globally, one of the most important farmed fish species. We have analyzed carp from a natural pond-production system in South Bohemia. Ongrowing fish had access to an abundant plankton population which was supplemented with cereals. Fatty acid composition (FA) was investigated in three parts of fillets from four crosses of carp. The FA composition of the leanest part, the dorsal white muscle was similar to that of marine-farmed species; it contained a large proportion of n-3 highly unsaturated FA, the n-3/n-6 ratio was 1.1, and the proportion of phospholipids was high. The abdominal wall is rich in monounsaturated FA, the n-3/n-6 ratio is lower, 0.5, and it is more affected by the cereal feed. We concluded that the lipid composition of all these carp tissues can be improved in terms of healthy FA profile.

The aim of the study was to determine the differences in the composition of fatty acids of intramuscular lipids between diploid (2n) and triploid (3n) tench of identical genetic specifications and raised under the same conditions, in relation to sex (F-female vs. M-male) and age (T 3 -36 months vs. T 3+ -42 months). A total of 137 tench (Tinca tinca L.) siblings were analyzed. The control group consisted of 72 diploid tench (39 F and 33 M) and the experimental group of 65 triploid tench (38 F and 27 M). Elevated levels of fatty acids C16:0, C16:1n-9c and C18:1n-9c were found in lipids of tench of both age groups (T 3 and T 3+ ). Among T 3 tench, significant ploidy-level related differences were ascertained in the content of specific SFA (C12:0, C13:0, C14:0, C15:0; p < 0.01) and C22:1n-9 (p < 0.05) in favour of 2n males. A significant effect of sex was found only in the diploid tench population: C14:0, p < 0.01 and C14:1n-9c, p < 0.05 in favour of 2n male tench and C18:1n-9c, p < 0.01 in favour of 2n female tench. In the T 3+ age group, the ploidy-level effect was apparent in both sexes (C15:0, P < 0.05 and C18:2n-9c, t11, p < 0.05 in favour of 2n female tench, C16:1n-9c, p < 0.01 in favour of 3n male tench, C18:2n-6c, p < 0.01 and C18:3n-3, p < 0.05 in favour of 2n male tench). In the T 3+ age group, the effect of sex was apparent for both ploidy levels (C16:1n-9c, p < 0.01 in favour of 2n female tench, and C14:0, p < 0.05 in favour of 3n male tench). The qualitative as well as quantitative composition of lipids of specific fatty acids was significantly affected (p < 0.05, p < 0.01, p < 0.05) by age. The study demonstrated that the factors monitored (ploidy, sex and age) may, under specific experimental conditions, influence the composition of lipid fatty acids of the tench. Fatty acids, diploid and triploid tench, genome polyploidyThe existing inter-and intra-species variability in the composition of fatty acids of fish lipids (and of the specific PUFA in particular) is usually explained by the existence of a large number of external factors (type of aquatic environment, type of rearing and the fish culture composition, trophic aspects -interaction, type and composition of diet, season of the year -water temperature) and internal factors (fish species, feeding regime and digestion, lifecycle stage, quantitative and qualitative characteristics of lipids -triacylglycerols, phospholipids and their topographical origin -dorsal vs. ventral part of muscle tissue).In recent years, there has been a large number of experimental studies (e.g. Csengeri et al. 1978;Farkas et al. 1978;Vanderwesthuyzen et al. 1984;Suzuki et al. 1986;Viola et al. 1988;Bieniarz et al. 2000) into some of the above factors (dealt with separately or in combination) causing changes in the composition of fatty acids in various fish species. Other authors have studied the impact that various types of heat treatment will have on the fatty acid composition (e.g. G all et al. 1983;Maeda et al. 1985;Tothmarkus and Sasskiss 1993;Fajmonová et al. 2003).I...

The aim of this paper was to investigate the constituent fatty acids of some freshwater fish species as well as compare the nutritional quality of freshwater fish with that of marine fish by comparing the levels of essential fatty acids present. The fatty acids profile of freshwater fish species include minor amounts of odd-number, branched-chain, and even-number fatty acids as well as saturated components, the monounsaturated fatty acids and polyunsaturated fatty acids. The major saturated fatty acids were C14:0 and C16:0. The C18:1 is the prominent monounsaturated fatty acids while the C18:2 is the dominant polyunsaturated fatty acids. The essential fatty acids compositions showed prominence in C18:3n-3 and C18:2n-6. The overall significance of this study had been its revelation that freshwater fish are good source of omega-6 essential fatty acids. The high percent of saturated fatty acids in freshwater fish gives them an advantage in curing processing.
