“…In gilthead sea bream (Sparus auratus) for example, stepwise increase in various plant oils to 80% of lipid caused reductions in both alternative complement pathway and head kidney phagocytic activity while moderate replacements have very few immunologic effects Wassef et al 2007). The most extreme groups of fish had a content of 22:6n-3 and 20:5n-3 amounting to 7% of lipid or 0.6 and 1.1% of diet respectively, which is very close to EFA deficiency in this species (Kalogeropoulos et al 1992;Ibeas et al 1994;. Reductions in the number of circulating leucocytes and macrophages have been noted in European sea bass (Dicentrarchus labrax) fed diets with 60% replacements of fish oils (Mourente et al 2005a).…”

“…Partial replacement of fish oil by vegetable oils in marine fish diets will only be possible when the essential fatty acid requirements are met. The replacement of fish oil by vegetable oils in marine fish diets has been studied in turbot (Regost et al, 2003a,b) and gilthead sea bream (Kalogeropoulos et al, 1992;Caballero et al, 2002;Izquierdo et al, 2003, in press), but few focused on the European sea bass, one of the most important marine finfish species for Mediterranean aquaculture (Yildiz and Sener, 2002;Izquierdo et al, 2003).…”

In the present study 75 g European sea bass were fed for 8 months with different diets (22% dietary lipid content) containing vegetable oils at two inclusion levels. The control diet (Diet FO) contained anchovy oil as the only lipid source; in diets 60RO, 60LO, and 60SO of fish oil was substituted by rapeseed, linseed or soybean oils, respectively; finally, in diet 80LO, 80% of the fish oil was substituted by linseed oil. Fish were fed to apparent satiation three times a day. All fish were individually weighed once per month. Lipid and fatty acid composition of diets and fish fillets were determined at the beginning, middle and end of the experimental period. Once the commercial size was reached, all fish were fed a 100% FO containing diet during 150 days.No significant differences were found in feed intake. Fish fed the diets containing 80% linseed oil or 60% rapeseed oil had significant ( P b 0.05) lower growth. Flesh fatty acid composition of total lipids reflected the fatty acids in the diets. Flesh contents of n-3 HUFA were reduced to about 45% in fish fed diets 60RO, 60LO or 60SO and to about 50% in diet 80LO. This reduction was markedly higher for EPA than for DHA. High levels of oleic, linoleic and linolenic acids were found in fish fed RO, SO and LO respectively.After 150 days of re-feeding period with a 100% fish oil diet, DHA levels were restored in those fish previously fed diets containing vegetable oils, but EPA levels remained lower when compared with fish fed 100% FO diet. Flesh content of linoleic and linolenic acids remained higher in those fish previously fed soybean and linseed oil containing diets, respectively.

“…However, in terms of cost, a combination of 32 g FO plus 48 g LO or SFO kg −1 diet can be also used with the least consequences on growth, feed utilization and nutrient retention efficiency. This notion is higher than the maximum level of FO-substitution by soybean oil (47%) in gilthead seabream juveniles diet (Kalogeropoulos et al, 1992) and closely resemble to that for cottonseed oil (Wassef et al, 2014) or a blend of soybeen, linseed and cottonseed oils (Wassef et al, 2007(Wassef et al, , 2009). …”

“…Ibeas et al (1996) estimated the optimal dietary level of n-3 LcPUFA in juvenile gilthead seabream to be 10 g kg −1 and further increases worsening the performance of the fish. Similarly, Kalogeropoulos et al (1992) estimated the required n-3 LcPUFA for this species in diets, with approximately 80-100 g kg −1 of lipid, to be approximately 19-23% of total fatty acids. These fatty acids have a sparing effect of protein in fish, and fish need these fatty acids for normal growth and a better feed conversion ratio (Watanabe, 1982).…”

“…It is well documented that, partial replacement of fish oil by vegetable would only be possible if essential fatty acids (EFAs) (primarily n-3 LcPUFA) in the diet were present in sufficient amounts to cover fish's need. For gilthead seabream, the minimum requirements for EPA and DHA were estimated to be around 0.9% of the diet (Kalogeropoulos et al, 1992;Izquierdo, 2005). It is clear, from the fatty acid profile of the experimental diets of this study (Tab.…”

-A feeding trial was conducted to define the optimal mixtures of either sunflower oil (SFO) or linseed oil (LO) with fish oil (FO), in fish meal (FM) based diets for gilthead seabream (Sparus aurata) fingerling, without significant effect on fish performance, fatty acid composition and liver structure. The trial lasted nine weeks with 420 fish (∼4.0 g) testing seven isonitrogenous (∼48% CP) and isolipidic (∼18% L) diets contained three incremental inclusions of either SFO or LO (40, 48, 56 g kg −1 ) and the only-fish oil control (CTRL) diet. Results showed that the combination of 32 g fish oil plus 48 g of either SFO or LO kg −1 diet as the lipid source had performed the best among all. Fatty acid (FA) composition of muscle lipids evidenced that specific fatty acids were selectively retained or utilized. Diet induced-changes in hepatic morphology with vegetable oil inclusion level were further described. Linolenic acid (α-LNA, n-3) had led to less pronounced steatosis symptoms than linoleic acid (LOA, n-6) in liver cells. This study provides sound support for the use of preferably sunflower oil then linseed oil as a complementary lipid resource (48 g kg diet −1 ) with marine fish oil in gilthead seabream fingerling diets. Therefore, represents novel data on the potential of using sunflower oil (SFO) as a possible dietary partial substitute of fish oil for the species.
