“…A similar result was obtained by Kutluyer et al (2017). In a previous study, Arslan et al (2012) found that Brown trout (Salmo trutta) fed with diets including a blend of soybean and linseed oils for 6 weeks had the greatest growth performance. The 30 th day results of our study were similar to the results of Arslan et al (2012), but after the 60 th day of trial, the difference between the FO and 50-50SO-LO diet groups became insignificant.…”

Black Sea trout (Salmo trutta labrax Pallas,1811) fed with diets based on 100% fish oil (FO), 67-33%, 50-50% and 33-67% soybean oil-linseed oil (SO-LO) during 90 days were affected in terms of weigth gain, specific growth rate, feed conversion ratio and hepatosomatix index significantly (P<0.05) while the survival rate was not affected at all. Tissue fatty acid profiles of the individuals were affected by the degree of dietary treatments (P<0.05). For instance, the highest linoleic acid (18:2n-6, LA) content of the muscle and liver tissues were exhibited in the group fed with 67-33 % SO-LO diet, where the highest linolenic acid (18:3n-3, LNA) was detected in the group fed with 33-67% SO-LO diet (P<0.05). In contrast to linoleic and linolenic acids, the highest values of palmitic (18:0), eicosepentaoneic (20:5n-3, EPA) and docohecsaenoic acids (22:6n-3, DHA) were indicated in group fed with fish oil based diet (P<0.05). Gene expression of desaturase in the muscle and liver tissues of individuals fed with 33-67% SO-LO included feeds were higher than those fed with FO. Similarly, gene expression of elongase both in the liver and muscle in individuals fed with (50-50% SO-LO, 33-67% SO-LO) and (50-50% SO-LO, 67-33% SO-LO) respectively were higher than those fed with FO. As a result, it was determined that use of 50-50% SO-LO in Black Sea trout diets is acceptable without an adverse effect on growth and feed conversion, and also this species have a capability of conversion 18:2n-6 to 20:4n-6 and 18:3n-3 to 22:6n-3.

“…However, although there was no significant difference between the TL values of the two treatments after 30 days, the Nile tilapias fed with the supplemented diet (TII) grew more and gained more weight to those fed with the control diet (TI). Arslan et al 48 and Montanher et al 37 also reported this behavior, i.e., the fish preference for diets supplemented with LNA.…”

In this study, the fatty acid (FA) composition of the Japanese grape (Hovenia dulcis) seed oil (JGSO) was firstly evaluated. It was found that the seed oil is rich in alpha-linolenic acid (LNA), containing approximately 425 mg LNA g -1 of total lipids. A fish diet supplemented with JGSO was prepared and supplied to Nile tilapia to investigate the FA composition of the fillets. For this, Nile tilapia were submitted to two feeding treatments: a control diet with 4.2% of soybean oil, and a diet supplemented with 4.2% of JGSO. The LNA, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) values increased significantly (406, 153 and 126%, respectively) with JGSO in the diet and with an increase in feeding time, while the nutritional quality indexes, n-6/n-3 ratio and index of thrombogenicity, decreased 2.8 and 1.4 times, respectively. Thus, the replacement JGSO in the diet raised the nutritional lipid quality in Nile tilapia.Keywords: fatty acids, omega-3, Oreochromis niloticus, supplementation, LNA IntroductionOmega-3 polyunsaturated fatty acids (n-3 PUFA), especially alpha-linolenic acid (LNA, 18:3n-3), eicosapentaenoic acid (EPA,, and docosahexaenoic acid (DHA,, have been extensively studied and said to be beneficial to human health. [1][2][3] A high ratio of dietary n-6/n-3 (omega-6/omega-3) has been reported around the world, reaching ratios between 15:1 and 20:1, while the recommended value is between 2:1 and 1:1. 4 This imbalance in the n-6/n-3 ratios is the result of an excess intake of omega-6 polyunsaturated fatty acids (n-6 PUFAs) from corn, soybean, and sunflower oils. Furthermore, a high intake of saturated fatty acids (SFA) such as myristic acid (14:0), palmitic acid (16:0), and stearic acid (18:0), may contribute to an increase in the indexes of atherogenicity (IA) and thrombogenicity (IT) 6 and to a reduction in the hypocholesterolemic/hypercholesterolemic fatty acid ratio (HH). 7Around the world, flaxseed, perilla, and chia are known sources of LNA, [8][9][10] while fish and microalgae oils rank among the most important sources of EPA and DHA. 11,12 The Japanese grape is originally from Japan, but has quickly expanded to other countries, such as India, Paraguay, Argentina, and Brazil, due to its easy adaptation to the soil and resistance to cold. 13 The Japanese grape are deciduous trees, growing to 10 to 15 m and reaching 20 to 40 cm in diameter of the trunk, commonly used for ornamental and reforestation purposes, and the wood for production of energy, paper and cellulose. The fruit is a small dry capsule from 6 to 7 mm in diameter containing 2 to 4 seeds, attached to a peduncle, which becomes thickened and fleshy when mature, which is also sweet and pleasant-tasting. The seeds are brown with a circular shape from 4 to 8 mm in diameter.14 The peduncles (pseudofruits) can be consumed in natura or in dehydrated form and are also used for alcoholic fermentation, to produce wine or vinegar. 15,16 According to Bampi et al. 13 the peduncles are rich in sugars and have a high content of dietary fi...

“…Brown trout can be considered as an important fish species in Turkey. It is highly accepted in Turkey and the local market value is higher than rainbow trout (Arslan, Sirkecioglu, Bayir, Arslan, & Aras 2012). Europe and Turkey are the natural distribution area of brown trout (Yeşilayer & Genç, 2013).…”

Fish are a unique dietary source beneficial to human health. These valuable effects originate from ω3 polyunsaturated fatty acids, particularly the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the fish oil. In this study, fatty acid composition of the muscle lipids of Salmo trutta macrostigma (wild brown trout) and Oncorhynchus mykiss (cultured rainbow trout) in Gezende Dam Lake were determined by gas chromatographic technique. In both species, palmitic acid (16.26-18.94%), oleic acid (17.88-20.49%) and DHA (14.08-18.49%) were identified as major saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA), respectively. Wild fish contained significantly more linolenic acid, arachidonic acid, eicosapentaenoic acid, docosapentaenoic acid, total ω3 fatty acids and has higher ω3/ω6 ratio than cultured fish. In conclusion, wild brown trout may have a higher nutritional value considering total ω3 fatty acids (35.52-27.43%) and ω3/ω6 ratio (3.84-1.56) compared to cultured rainbow trout.
