“…The results of our study indicate that the fish fed diets with up to 1000 g/kg SO exhibited good growth performance compared with fish fed the basal diet (1000 g/kg FO diet). This finding is consistent TA B L E 7 Effects of replacing fish oil with soybean oil on the liver enzyme activities of Epinephelus coioides with the results of previous studies on groupers (Lin et al, 2007;Yan et al, 2020) and other fishes that were fed diets using SO (Alvarez et al, 2020;Sanchez-Moya et al, 2020;Wang et al, 2018) and other VOs, either alone or mixed, as complete substitutes (Bell et al, 2001;Deng et al, 2014;Glencross et al, 2016;Monge-Ortiz et al, 2018;Mozanzadeh et al, 2016;Seno-O et al, 2008;Yildiz et al, 2018;Yu et al, 2019). In contrast, some studies have shown that high dietary inclusion levels of SO can result in poor growth in marine and freshwater fishes (Chen et al, 2020;Emre et al, 2016;Gonzalez-Felix et al, 2016;Li, Mai, et al, 2016;Mu et al, 2018;Peng et al, 2008Peng et al, , 2014Trushenski et al, 2011).…”

“…It is thus understandable that the lowest n-3/n-6 PUFA ratio in the 1000 g/kg SO diet contributed to the maximum lipid accumulation in the liver, as evidenced by a study on gilthead sea bream fed either an 800 g/kg linseed oil or an 800 g/kg SO diet (Menoyo et al, 2004). Therefore, the high dietary SO inclusion could reduce flesh quality and fillet nutritional value, in terms of the edible value of fish (Alvarez et al, 2020;Yildiz et al, 2018;Yu et al, 2019) and the lower LC-PUFA and n-3/n-6 PUFA levels in the high SO diets, especially the two important EFAs (DHA and EPA), compared with the basal diet that may also affect the quality of flesh and the nutritional value of the fillets (Bell et al, 2002;Deng et al, 2014). On the other hand, although the increasing dietary SO inclusion levels did not affect the whole-body and muscle composition, they influenced the liver FA composition.…”

“…This alternative approach to the formulation of aquafeeds offers promising results. However, the results vary when vegetable oils (VOs) are used in commercial feed formulations for farmed fish, which is generally attributed to the inconsistent nutritional quality of these oils (Alvarez et al, 2020;Fountoulaki et al, 2009;Kamarudin et al, 2012;Mjoun et al, 2012;Mu et al, 2020;Sanchez-Moya et al, 2020;Yildiz et al, 2018). Soybean oil (SO), with its wide availability and relatively low price, has been become the preferred FO substitute.…”

“…Considerable and successful efforts have been made to substitute SO for FO in practical aquafeeds; the substitution level is in the range of 480-1000 g/kg (Emre et al, 2016;Gonzalez-Felix et al, 2016;Peng et al, 2008;Trushenski et al, 2011). However, although many studies have shown that the complete replacement of FO or high dietary SO inclusion did not hinder the normal somatic growth of fish, they have some disadvantages, such as increased liver lipids (Mu et al, 2018;Peng et al, 2014;Ruyter et al, 2006), undesirable fatty acid (FA) profiles in the fillet (Alvarez et al, 2020;Gonzalez-Felix et al, 2016;Mu et al, 2018;Sanchez-Moya et al, 2020), reduced liver anti-oxidative capacity (Mu et al, 2018;Peng et al, 2008) and enhanced inflammatory responses (Mu et al, 2018).…”

The aim of this study was to investigate the effects of substituting soybean oil (SO) for fish oil (FO) on the performance, tissue fatty acid (FA) composition, plasma components, liver metabolic enzyme activity and mRNA levels of genes related to lipid metabolism in the liver of groupers (Epinephelus coioides). We formulated five isolipidic and isoproteic diets with increasing SO levels (0, 250, 500, 750 and 1000 g/kg, respectively). Triplicate groups of 30 groupers (initial mean body weight of 12.6 g/ fish) were fed one of the diets twice daily, to apparent satiety across a feeding period of 56 days. The growth performance, whole-body composition, and protein and lipid muscle contents did not differ across the dietary treatments. In contrast, the liver lipid content had positive linear and quadratic responses to the increasing dietary SO levels, but the liver protein content had the opposite trend, and the highest lipid value and lowest protein value occurred in the 250 and 1000 g/kg SO diets, respectively. There were no significant effects of increasing dietary SO inclusion levels on any of the plasma components and parameters of liver metabolic enzyme activity, except for acetyl coenzyme A carboxylase and hepatic lipase, which showed linear and quadratic responses to increasing dietary SO inclusion levels and peaked at 1000 and 250 g/ kg SO inclusion level, respectively. However, the FA profiles of the dorsal muscle and liver generally reflected the FA profile of the diet. Furthermore, the mRNA levels of fas, acc, g6pd, lpl, pparα, cpt-1, srebp-1c, δ6fad and elovl5 in the liver exhibited positive linear and/or quadratic responses to dietary SO inclusion levels. However, negative linear and/or quadratic responses were observed for the mRNA levels of hsl and atgl in the liver, with increasing dietary SO inclusion levels. The mRNA levels of scd and fabp in the liver were not affected by the dietary SO inclusion level. These results indicate that FO could be replaced completely by SO without affecting growth. However, the inclusion of SO at levels higher than 500 g/kg could compromise the FA profile in the liver and flesh of the fish species. These results provide a novel insight into the potential utilization of SO in grouper feeds. | 1495 HE Et al.

“…Grigorakis (2007) reported that while the atherogenic index of animals fed a diet in which fish oil is the only oil source was 0.62–0.64, this value was in the range of 0.34–0.53 in animals fed a diet derived from vegetable oils. Álvarez et al (2020) was also reported that the observed differences between both fatty acid profile and quality parameters in gilthead seabream fed with fish and vegetable oil diets did not have a negative effect on health or quality indexes. These results show that the inclusion of vegetable oils in fish diets reduces the atherogenic index of the final product.…”

The aim of this study was to evaluate the effects of alternate feeding regime with fish oil‐ and peanut oil‐based diets on fatty acid profiles and growth performances of European seabass fingerlings (Dicentrarchus labrax). Six trials were implemented; fish oil trial [C; continuously fed by diet with fish oil (FO)], peanut oil trial [P; continuously fed by diet with peanut oil (PO)], mixture oil trial (PC; continuously fed by diet containing both %50 FO and %50 PO), alternate cycled feeding three trials [(3P/3C; fish fed by diet with PO for 3 weeks and FO for the following 3 weeks), (3PC/3C; fish fed by diet with PC for 3 weeks and FO for following 3 weeks) and (9P/3C; fish fed by diet with P for 9 weeks and C for following 3 weeks)] for 12 weeks. Significantly higher SGR and the best FCR were detected in P and 3PC/3C and 9P/3C groups, respectively, compared with C group (p > 0.05). The lowest HSI and VSI were in the C group (p > 0.05). The highest crude protein was determined in 3P/3C group while protein ratios were higher in cycled fed groups than in the experimental groups (p > 0.05). The highest crude lipid were detected in P group (p > 0.05). The higher SFA level was detected in 9P/3C group (p < 0.05), whereas C group had the lowest content. While P group had the highest fillet MUFA content, which was predominantly made up of OA, the lowest MUFA was determined in the 3PC/3C and C groups. The highest LA was observed in C group (p < 0.05). The ArA was higher in the cycled fed groups than the diet groups. EPA, n‐3 PUFA and n3/n6 rates were significantly higher (p < 0.05) in cycled fed groups, compared with the diet groups. The DHA ratio was significantly lower in 9P/3C group compared with the other groups. Also, the lipid quality of the flesh was directly related to the EPA and DHA ratios, and a higher quality product was revealed at the end of cycled feeding with the low IA, IT and high FLQ and h/H values obtained. This study shows that cycled feeding regimes by diets including vegetables oil and FO may be used in European seabass culture.

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.
