“…Catfish (S. glanis) from the Adana Seyhan Dam Lake contained 0.54 % (Ozogul et al 2007), and the same species from Greece had 3.5 % fat (Aggelousis and Lazos 1991). Olgunoglu et al (2014) also reported seasonal variation of lipid content in the S. triostegus in the Atatürk Dam Lake. In their study, the total lipid contents were 4.…”

Fatty acid (FA) compositions of total lipid, phospholipid (PL) and triacylglycerol (TAG) fractions have been determined in muscle tissues of Silurus triostegus. The distributions of saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) proportions were found to be different among total lipid, PL and TAG fractions from lipids in muscle tissues of the male and female S. triostegus in all seasons. Triacylglycerol contained a lower proportion of PUFA and a higher proportion of MUFA and SFA than PL while PL contained higher proportion of PUFA than proportion of MUFA and SFA compared to TAG. Triacylglycerol and PL fatty acid compositions in muscle tissues of the male and female fish species were found different. The most abundant fatty acids in the investigated seasons were palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1 n-9), palmitoleic acid (C16:1 n-7) and docosahexaenoic acid (C22:6 n-3). It was shown that the total lipid content and FA compositions in muscle tissues of the male and female S. triostegus were influenced by reproduction period and season.

“…The highest value was detected in autumn (5.26, 4.80%, respectively). Olgunoglu et al (2014) determined the highest energy value for Silurus triostegus to be in the winter months when the lipid content was at its highest. Considering that the energy levels are related to the lipid content, it can be said that the energy value reached its highest level in the autumn months for G. rufa.…”

Specimens of Garra rufa were collected from a warm river and a cool stream in the Bingöl Province, Turkey, once a month over a period of one year. The effects of month, season, gender and location on the fatty acid composition in the muscle and the lipid content were investigated and dietary marker fatty acids were used to obtain dietary preferences in different locations (Ilıcalar, Garip) and periods. Total lipid change was seasonally significant (ANOSIM-R=0.49) at both locations and 18:1ω9, 20:5ω3 and 20:6ω3 were the most abundant dietary fatty acids. Although G. rufa are predominantly herbivores, they can also feed omnivorously on mixed diets depending on the presence and absence of their primary diet. The effect of season was significant on fatty acid composition, regardless of the location (Pperm=0.001). Significant seasonal changes in all the fatty acid compositions could be attributed to seasonal changes in the abundance and diversity of dietary sources in the environment due to the effect of temperature.

“…For example, Ca, P and Mg contribute to bone health, Na is important for nerve and muscle function and K aids in nerve function and muscle contraction. On the other hand, micro elements such as Iron (Fe), Zinc (Zn), Copper (Cu) and Chromium (Cr), though essential for human life, can have varying effects, either beneficial or harmful, depending on their concentrationoften equivalent to less than a teaspoon per person's body weight (Artar et al, 2022;Olgunoglu et al, 2014). As a result, the consumption of fish or the supplementation of fish oil, whether from freshwater or marine sources, is highly encouraged (Kumaran et al, 2012).…”

Background: Fish, owing to its nutritional attributes, serves as a pivotal component of a wholesome diet. The constituents found in fish, specifically macroelements and polyunsaturated fatty acids (PUFA), play a crucial role in promoting human health. This study investigates the fatty acid profiles and macro element contents of economically significant fish species, including garfish (Belone belone), European barracuda (Sphyraena sphyraena) and anglerfish (Lophius piscatorius), with a specific focus on gender-based differences. The research addresses a notable gap in existing literature, providing a comprehensive evaluation of the nutritional quality of these species. Methods: In February 2023, marine fish species, were obtained from the Aegean Sea located between the western and southwestern shores of Türkiye and the eastern shores of Greece. A total of fifteen samples, representing each fish species and gender within the sampling area, were collected for the analysis of fatty acids and macro elements. Result: The findings of this study indicate that, regardless of fish species and gender, the major fatty acids in the SFAs, MUFAs and PUFAs classes were palmitic (C16:0), oleic (C18:1n-9) and DHA (C22:6n-3), respectively. The examined species in this study exhibit average macro element levels. While PUFA, EPA and DHA values meet target levels of content for human health and quality food consumption, achieving these levels minimally implies that the studied species lack a rich fatty acid profile compared to those in prior research. Nonetheless, it is concluded that monitoring seasonal variations is essential for a comprehensive understanding of their fatty acid composition.
