“…There were no differences in fillet fatty acid profiles, except for stearic acid and DHA between AFD and AFT groups in our study. Similar results were reported for diploid and triploid tench (Tinca tinca L.) (Buchtova, Smutna, Vorlova, Svobodova, & Flajshans, 2004), rainbow trout (Manor, 2009;Picklo, Raatz, Cleveland, & Rexroad, 2013), and masu salmon (Oncorhynchus masou) (Wang, Xu, Bai, Yin, & Jia, 2015). The results indicate that triploid fish have sufficient fatty acid amounts for human consumption.…”

SummaryThis study compares the performance (in terms of survival and growth), biochemical and fatty acid compositions among all female diploid (AFD) and triploid (AFT) rainbow trout (Oncorhynchus mykiss). AFD and AFT fish with mean initial weights of 1,040.1 ± 1.3 and 1,039.7 ± 1.6 g, respectively, were reared and fed from March to August with a commercially extruded trout feed in a commercial freshwater fishfarm located in the Black Sea region (Samsun, Turkey). Survival was reduced throughout the experimental period in the AFT group with increasing water temperatures. At the end of the experiment, survival rates were 98.57 ± 1.43% and 82.38 ± 7.39% for the AFD and AFT groups, respectively. The AFD group showed significantly better growth performances in terms of weight gain, feed conversion rate (FCR), relative growth rate (RGR) and specific growth rate (SGR) than the AFT group (p < .05). Significantly less protein and greater fat content were also observed in the AFT group (p < .05). There was no significant difference between groups for fatty acid composition in meat, except for stearic acid (SA, C18:0) and docosahexaenoic acid (DHA, 22:6 n-3). While the greatest SA concentration was in the AFT group, the greatest DHA concentration was observed in the AFD group (p < .05). The results indicate that female triploid rainbow trout are more susceptible to suboptimal environmental conditions (especially to higher water temperatures) than female diploids. Although poor triploid performance was observed in this study, relative productivity might be enhanced by rearing triploids in optimal environmental conditions.

The aim of the study was to determine the differences in the composition of amino acids (in % of total determined amino acids) 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 38 mixed samples of muscle tissue from 137 tench divided by sex, ploidy and age were analyzed. The effect of ploidy and sex on the composition of the spectrum of amino acids of muscle proteins was greater in the T 3 tench population. The following differences in values were found: female fish (ploidy effect): Thr (p < 0.05), Arg (p < 0.05), Pro (p < 0.01) Gly (p < 0.01); male fish (ploidy effect): Ile (p < 0.01); diploids (sex effect): Arg (p < 0.05); triploids (sex effect): Pro (p < 0.01). In the T 3+ tench population, highly significant (p < 0.01) differences in Gly contents in female fish (ploidy effect) and triploids (sex effect) were found. Lower levels of the following amino acids were found in muscle tissue of T 3+ tench compared with the T 3 (younger) tench population: Val, Phe, Lys, His, Arg (in F 2n and M 3n), Pro (in F 3n) and Tyr. Levels of Thr, Ile, Leu, Arg (in M 2n and F 3n), Asp, Glu, Gly and Ala, on the other hand, were higher in T 3+ tench. Results of the present study suggest that the qualitative and quantitative compositions of some amino acids bound in tench muscle proteins may be statistically significantly influenced by such biotic factors like sex, ploidy and age. Fish, tench, genome manipulations, polyploidy, essential and non-essential amino acidA large number of research teams study the quantitative and qualitative composition of amino acids of bodily tissues and fluids of fish. They mainly focus on investigating the effects that diets (different contents of proteins and lipids) may have on the composition of free amino acids (FAA). In different species of fish, considerable variations in the composition of amino acids, particularly in studies of free essential amino acids (FEAA) in blood plasma, are demonstrated. A high degree of correlation between diet composition and FEAA levels in blood plasma in the common carp has been reported by, e.g., Plakas et al. (1980), Dabrowski (1982, Schwarz et al. (1984), Zeitler et al. (1984) and Ogata (1986), in the rainbow trout by Kaushik and Luquet (1977 a,b), Walton and Wilson (1986), Yokoyama and Nakazoe (1991) and Yokoyama et al. (1994), in the salmon by Ogata and Murai (1994) and in the sturgeon by Kaushik et al. (1994). Schwarz and Kirchgessner (1988) found that dietary levels of crude protein (CP) exceeding 41% cause a significant increase in certain free non-essential amino acids (FNEAA), while high-energy diets (over 18.2 MJ) will cause their reduction.

“…The external factors are environment, culturing method, and tropic effects. The internal factors include fish species, feeding regime and digestion, life cycle stage, quantitative and qualitative characteristics of lipids-triacyglycerols, phospholipids and their topographical origin-dorsal and ventral part of muscle tissue (Buchtova et al, 2004).…”

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.
