“…In present study, palmitic acid was identified as the primary FA in fish muscle and it constituted 60%–70% of total SFA. These findings comply with the findings of earlier studies (Alasalvar et al, ; Nettleton & Exler, ; Ozogul, Polat, Ucak, & Ozogul, ; Yeşilayer & Genç, ; Yıldız et al, ). Although fish SFA contents were relatively high (>% 35) (Table ), they comply with the findings of Nettleton and Exler (), and Oztekin et al ().…”

Isocaloric and isonitrogenic balances of previous studies were taken into consideration while preparing experimental diets (Kader & Koshio, ; Tırıl, Alagil, Yağcı, & Aral, ; Tusche et al, ; Yıldız, Eroldoğan, Ofori‐Mensah, Engin, & Baltacı, ).…”

“…The muscle lipids and FA profiles of the experimental diets were similar with several earlier reports. Muscle lipids designate the source of dietary lipids (Alasalvar, Taylor, Zubcov, Shahidi, & Alexis, ; Arzel et al, ; Yıldız et al, ).

“…C22:6 n ‐3 (DHA) was not identified in experimental groups, except for the 2% betaine group with 50% dietary soybean meal incorporation. The n‐3 PUFA deficiency negatively influenced optimal growth of rainbow trout, thus lower growth rates were observed in control groups (Bell, Dick, & Porter, ; Güler & Yıldız, ; Sargent, Tocher, & Bell, ; Tocher, ; Yıldız et al, ).…”

This study was conducted to investigate the effects of dietary incorporation of soybean meal for fish meal replacement and supplementation of betaine as an attractant on growth performance and fatty acid profiles of rainbow trout (Oncorhynchus mykiss). Juvenile trout were fed practical diets, with increasing soybean levels and betaine supplementations. The experimental diets consisted of a control diet with fish meal as the sole protein source (control) and no attractant, 25% soybean‐1% betaine diet (SBM25‐B1), 50% soybean‐2% betaine diet (SBM50‐B2), and 50% soybean‐0% betaine diet (SBM50‐B0). Average body weight was 12.69 ± 0.16 g at the beginning of experiments. Following 54 days feeding programme with experimental diets, average body weights reached 47.45 ± 1.22 g, 58.11 ± 1.77 g, 56.34 ± 1.87 g and 53.76 ± 1.74 g in the control, SBM25‐B1, SBM50‐B2 and SBM50‐B0 groups respectively. As compared with control treatment, significant differences were observed in weight gain, specific growth rate and feed intake of 1% betaine treatment at 25% soybean‐meal‐incorporated diet (p < .05), but no differences were observed in feed conversation ratio and survival rates (p > .05). Compared with the control treatment, betaine‐supplemented groups had significantly higher total saturated fatty acid contents (p < .05). On the other hand, the control treatment showed a significantly higher level of monounsaturated fatty acid than the betaine‐supplemented groups (p < .05). Significant differences were observed in fatty acid profile of 1% betaine‐supplemented group (p < .05) compared with the control. Present findings revealed that 1% betaine supplementation with dietary incorporation of soybean meal at 25% level positively influenced growth performance, feed utilization and fatty acid profiles of rainbow trout juveniles.

This study assesses the effect of inclusion of n–3 C18 rich oils on nutrient profile and quality of flesh in gilthead seabream (≈ 61.5 g) after feeding isoproteic and isolipidic diets in which camelina seed (CSO) or chia oil (CO) totally or partially replaces fish oil (FO) for 110 days. Fillet fatty acid (FA) profile reflects dietary FA profile, characterized by increased C18 polyunsaturated FA (PUFA) and a reduced highly unsaturated FA, whereas n–3/n–6 ratios are increased in fish fed diets with CSO or CO content. However, indices of atherogenicity and thrombogenicity, calculated from the fillet FA profile as indices for the health quality for consumers, are reduced with dietary addition of CSO or CO due to the increased fillet content of C18 n–3 PUFA in CSO and CO fed fish. In spite of the differences in fillet FA profiles, sensory quality of flesh does not vary among fish from different dietary groups. Instrumental texture and color analyses reveal significantly different values in cooked fillets in comparison to the raw fillets. Overall, dietary inclusion of CSO or CO enhances the nutritional value of fish flesh as well as the production of healthier fillets. Practical Applications: This study suggests fish oil could be totally replaced with camelina or chia oil in the diet of gilthead sea bream without negatively affecting sensory characteristics. The dietary inclusion of these oils could enhance the nutritional quality of fish fillets, and could receive wide application in the aquafeed and animal feed producing sector.

The main objective of this study was to determine the best vegetable oils (VO) for nutrition of African catfish by assessing the effects of a complete replacement of fish oil (FO) by different VO sources on its growth performance, fatty acid composition, and elongase-desaturase gene expression levels. Fish (16.2 g of initial body weight) were fed with five experimental isonitrogenous, isolipidic, and isoenergetic diets in which FO was totally replaced by cottonseed oil (CO), palm oil (PO), desert date oil (DO), or Shea butter (SB). Complete replacement of FO with VO did not affect growth performance except for low values in fish fed SB diet. Muscle n-3 LC-polyunsaturated fatty acids (PUFA) were significantly reduced in fish fed VO-based diets when compared with FO fed fish. However, the muscle arachidinic acid (ARA) levels in phospholipid class were 1.4 to 1.6 times higher in fish fed CO and DO diets than FO fed fish despite the lower ARA suppliers from these VO-based diets, suggesting endogenous LC-PUFA biosynthesis from PUFA precursors in fish fed these VO. The fads2 and elovl5 gene expression levels in liver of fish fed DO were also higher compared to FO controls. Therefore, all the results support the hypothesis that African catfish has higher biosynthesis capacity to convert vegetable n-6 PUFA precursors like linoleic acid (LNA, 18:2n-6) into n-6 LC-PUFA of the ARA type, compared to the conversion of vegetable α-linolenic acid (ALA, 18:3n-3) into n-3 LC-PUFA of the eicosapentanoic acid (EPA) or docosahexanoic acid (DHA) type. The results also indicate that DO can be recommended as the best alternative to FO replacement in African catfish nutrition.
