“…Observed mortalities in this study could have been as a result of stocking relatively small fish Bransden et al (2003) observed similar mortalities in their investigations on the replacement of fish oil (FO) with sunflower oil (SFO) in the feeds for Atlantic salmon (Salmo salar L.). No apparent EFA deficient signs such as fin erosion and bacterial disease (Castell et al 1972) were observed during the feeding trial.…”

“…The replacement of fish oil with palm oil in the diet of Clarias gariepinus did not significantly affect growth. Bransden et al (2003) similarly observed no significant differences in weight gain, total feed consumption, feed efficiency ratio for Atlantic salmon fed with SFO as partial replacement for FO.…”

“…Attempts have been made at partially substituting or replacing fish oils with vegetable oils (Bell et al (1991(Bell et al ( , 1996, Bransden et al, 2003. ) Fish oil substitution must however be done such that the product quality in terms of long chain n-3 poly unsaturated fatty and (PUFA) content as well as the eating quality are not diminished.…”

This study was conducted to investigate the effect of the substitution of fish oil with palm oil in the diet of Clarias gariepinus fingerlings over a 49 day period. Four diets were prepared with fish oil substituted with palm oil at 0% (control Diet 1), 25% (Diet 2), 50% (Diet 3) and 100% (Diet-4), using a completely randomised block design. Mortality was observed in all the treatments, while fish fed with 100% palm oil were most sluggish in accepting their feeds. Average weight gained, specific growth rate and feed conversion efficiency were not significantly affected by diet. It was concluded that palm oil can be substituted for fish oil in the diet of C. gariepinus.

“…However, the finite and limited supply of these marine ingredients, as well as the continued increase in aquaculture production, has resulted in a research for alternative raw materials for aquafeeds (11)(12)(13)(14) . In this context, considerable research has focused on sustainable alternatives such as terrestrial plant sources (15,16) , which have been demonstrated to be suitable for Atlantic salmon (Salmo salar L.) growth (11,(17)(18)(19)(20) . A considerable body of literature exists regarding the effect of FM/FO substitution on the n-3 LC-PUFA content of fish, although limited attention has so far been focused on the effect of this substitution on other beneficial nutrients such as Se.…”

Modulation of selenium tissue distribution and selenoprotein expression in Atlantic salmon (Salmo salarL.) fed diets with graded levels of plant ingredients

Increased substitution of marine ingredients by terrestrial plant products in aquafeeds has been proven to be suitable for Atlantic salmon farming. However, a reduction in n-3 long-chain PUFA is a consequence of this substitution. In contrast, relatively little attention has been paid to the effects of fishmeal and oil substitution on levels of micronutrients such as Se, considering fish are major sources of this mineral for human consumers. To evaluate the effects of dietary marine ingredient substitution on tissue Se distribution and the expression of Se metabolism and antioxidant enzyme genes, Atlantic salmons were fed three feeds based on commercial formulations with increasing levels of plant proteins (PP) and vegetable oil. Lipid content in flesh did not vary at any sampling point, but it was higher in the liver of 1 kg of fish fed higher PP. Fatty acid content reflected dietary input and was related to oxidation levels (thiobarbituric acid-reactive substances). Liver had the highest Se levels, followed by head kidney, whereas the lowest contents were found in brain and gill. The Se concentration of flesh decreased considerably with high levels of substitution, reducing the added value of fish consumption. Only the brain showed significant differences in glutathione peroxidase, transfer RNA selenocysteine 1-associated protein 1b and superoxide dismutase expression, whereas no significant regulation of Se-related genes was found in liver. Although Se levels in the diets satisfied the essential requirements of salmon, high PP levels led to a reduction in the supply of this essential micronutrient.

“…Despite, LO have already been studied, either singly or mixed, within highly energetic (25% L) fish meal (FM)-based diets (Izquierdo et al, 2003) or plant-protein rich diets (Benedito-Palos et al, 2008) for gilthead seabream, the high level of n-3 LNA makes this oil relatively unique in being able provide dietary n-3 PUFA at a potentially cost effective rate. On the other hand, reports on using sunflower oil (SFO) as a possible substantial partial substitute for dietary fish oil were mostly limited to Atlantic salmon, Salmo salar (Bell et al, 1993;Bransden et al, 2003;Menoyo et al, 2007;Torestensen et al, 2000), and European seabass, Dicentrarchus labrax (Yildiz and Sener, 2004). Moreover, the high levels of dietary fish oil substitution up to 80% or 100% in gilthead seabream feeds had evidenced to result in a remarkably reduced growth performance and feed utilization efficiency and increased feed conversion ratio as well as liver weight and lipid content (Glencross, 2009;Izquierdo et al, 2005;Menoyo et al, 2004;Nasopoulou and Zabetakis, 2012).…”

-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.
