Rapeseed (Canola) Oil and Other Monounsaturated Fatty Acid-Rich Vegetable Oils

Effects of alternate feeding with different lipid sources on fatty acid composition and bioconversion in European sea bass (Dicentrarchus labrax)

“…With respect to fish oil replacement, practical alternatives at present include vegetable oils that lack the omega-3 long chain polyunsaturated fatty acids (n − 3 LC-PUFA), eicosapentaenoic (20:5n − 3, EPA) and docosahexaenoic (22:6n−3, DHA) acids. Canola oils are among the most abundantly produced vegetable oils globally, and are good candidates to replace of aquaculture feeds (Gunstone, 2010;Turchini and Mailer, 2010). The potential replacement of fish oil with canola oil into fish feeds was previously investigated, particularly for their ready and constant availability, relatively low price and energy availability (Turchini and Mailer, 2010).…”

Studies on the effects of reduced n−3 LC-PUFA relative to inclusion levels of vegetable oil at around 50-80% on growth performance of marine species, especially sea bass and sea bream (Sparus aurata), are contradictory (Izquierdo et al, 2003;Nikzad et al, 2012;Xu et al, 2012;Eroldoğan et al, 2012Eroldoğan et al, , 2013Özşahinoğlu et al, 2013), but predominantly resulted in a 50% reduction in EPA and DHA flesh concentrations in sea bass (Bell and Waagbø, 2008).…”

Determination of Hematological Status as Health Indicator of European Sea Bass (Dicentrarchus labrax L.) Fed Different Dietary Fatty Acids

“…However in the present study, there were no any symptoms of anaemia, hyperthermia and hypoxia condition related with dietary lipid sources. Wassef et al (2007) found that a slight deformation in erythrocyte shape was noticed in the blood films of fish fed the vegetable oil (cotton seed oil 60% and linseed oil 60%) diets. In the meantime, no remarkable blood cell morphology alteration was noticed between fish fed control diet.…”

“…In previous studies, it has been reported that n-6 PUFA and n-3 MUFA which were used in feed alternatives to fish oil, had no negative effects on fish growth; on the contrary, it was even reported that they supported the growth (Turchini and Francis, 2009;Turchini and Mailler, 2010;Eroldoğan et al, 2013). In particular, MUFA rich canola oil is not prone to oxidation due to its low melting point and natural antioxidant contents, increased digestibility and usability of feed in hot climates.…”

“…There have been numerous studies into the effects of balanced diet contents on hematological parameters (Robinson and Daniels, 1987;Mourente et al, 2007;Wassef et al, 2007).…”
