Effects of dietary canola oil level on growth, fatty acid composition and osmoregulatory ability of juvenile fall chinook salmon (Oncorhynchus tshawytscha)

Response of Rainbow trout (Oncorhynchus mykiss ) to unrefined peanut oil diets: Effect on growth performance, fish health and fillet fatty acid composition

“…Our results are in accordance with Grant et al. () who fed juvenile chinook salmon with canola oil up to 54 g/kg of the total dietary lipid content. Likewise, Parpoura and Alexis () reported similar results for sea bass fed with different vegetable oil sources.…”

Partial or total replacement of dietary fish oil with alternative lipid sources in silvery-black porgy (Sparidentex hasta)

“…The increase in lipid retention in fish fed the SO diet may be due to an increase of LA in the whole body of fish and the imbalance in the n − 3/n− 6 ratio, as well as changes in lipid metabolism by reducing the activity of enzymes involved in the esterification of free fatty acids into triacylglycerol and phospholipid for very low density lipoprotein production, and thereby leading to increase of lipid deposition (Ruyter et al, 2006). This phenomenon was previously reported in other fish species (Brandsen et al, 2003;Grant et al, 2008;Karalazos et al, 2011Karalazos et al, , 2014Peng et al, 2008Peng et al, , 2014. The complexion of interactions between different FAs have drastic effects on assimilation and catabolization of FA from alternative lipid sources in various tissues .…”

Effects of Alternative Dietary Lipid Sources on Growth Performance and Fatty Acid Composition of Beluga Sturgeon, Huso huso, Juveniles

“…Mean weight gain (WG, g) per fish was calculated from the sum of weight gains in the first and second periods (geometric average body weight). The following indices were used: condition factor (CF; Grant et al 2008); daily feed intake (DFI, % BW/d; Hatlen et al 2005); feed conversion ratio (FCR; Turchini et al 2003); hepatosomatic index on harvesting day (HSI, %; Turchini et al 2003); lipid retention efficiency (LRE, %; Wang et al 2009); protein efficiency ratio (PER, g/g; Huang et al 2007); and survival ( S , %; Huang et al 2007) using the following formulas: where BW indicates the total body weight (g) and BL the total body length (cm) of the H. huso .…”

“…Differences between means were assessed by Duncan's multiple range test (Duncan, 1955) and linear regression was carried out between survival rate and experimental diets. Graphical relationships were obtained between the concentrations of selected dietary fatty acids and those noted for the respective fatty acids in the muscle lipids according to Bell et al (2001) and Grant et al (2008) to gain additional insights into the metabolic fates of these fatty acids. Excel, Microsoft Office, 2007, and SPSS version 13.5 (SPSS Inc., Chicago, IL, USA) were used for data manipulations and statistical analysis.…”

“…Vegetable oils are a favored alternative because they are readily available, relatively stable in price (Izquierdo et al 2003), and virtually free of dioxins and other organic pollutants (Figueiredo‐Silva et al 2005). Global production of vegetable oils are around 100 times higher than that of FO and a number of studies have shown that they can replace total or significant parts of the FO in diets for fishes such as Atlantic salmon, Salmo salar (Bell et al 2001); rainbow trout, Oncorhynchus mykiss (Caballero et al 2002); African catfish, Clarias gariepinus (Ng et al 2004); Murray cod, Maccullochella peelii peelii (Francis et al 2006); white bass, Morone chrysops (Lane and Kohler 2006); chinook salmon, Oncorhynchus tshawytscha (Grant et al 2008); and also some sturgeon species such as white sturgeon, Acipencer transmontanus (Xu et al 1993); Adriatic sturgeon, Acipencer naccarii (McKenzie et al 1999); and Russian sturgeon, Acipencer gueldenstaedtii (Şener et al 2005), without compromising growth, feed efficiency, or reproduction. Notably, there is presently a lack of information concerning the potential of including alternative lipid sources in practical diets of H. huso on the growth, feed efficiency, and body composition.…”
