Effects of safflower oil supplementation in diet on growth performance and body fatty acid composition of turbot (Psetta maxima)

Abstract

The aim of the study was to investigate the effects of the diets that contain safflower oil and fish oil as lipid sources, on growth, feed conversion and body composition in turbot (Psetta maxima). Two iso-nitrogenous and iso-lipidic diets (55 % protein and 14 % lipid) were prepared that include 100 % fish oil (FO group) and 100 % safflower oil (SFO group) for turbots with average weight of 62.21 ± 1.28 g, and fish were fed with these diets for 104 days. At the end of the experiment, the weight gain, specific growth rate and feed conversion ratio were the highest in SFO group than in FO group (p \ 0.05). Fatty acid composition of fish body reflected the fatty acid composition determined in the experimental diets. The amounts of palmitic acid (PA; C16:0), oleic acid (OA; C18:1n-9), linoleic acid (LA; C18:2n-6) and docosahexaenoic acid (DHA; C22:6n-3) were dominant fatty acids in fish body. It was confirmed that the usage of safflower oil instead of fish oil in turbot feed did not generate any negative effects on growth, feed conversion and the values regarding the growth performance.

Effects of Canola and Safflower Oil Supplementation in Diets, on Growth Performance and Fatty Acid Composition of Russian Sturgeon (Acipenser gueldenstaedtii Brandt, 1833)

“…The replacement of 50% dietary fish oil with unrefined peanut oil had no adverse effect on the growth performance of common carp (Yildirim et al 2013). There were no significant effects on weight gain in White sturgeon (Xu et al 1993) and no negative effects on growth of turbot fed diets containing SFO (Bell et al, 1994;Altundag et al 2014). Partial replacement of cod liver oil with either linseed or SFO did not have a negative effect on growth performance in juvenile Eurasian perch (Blanchard et al 2008).…”

“…Regarding other medical herbs and oils, Sahu et al (2008) reported significant increase in specific growth rate in Labeo rohita fingerlings fed diets contained four levels from turmeric (0.1, 0.5, 1.0 and 5g ). Altundag et al (2014) reported significant differences in specific growth rate in favor of diets contained sun flower oil (0.65%) compared to diets contained fish oil (0.58%) in a study on turbot (Psetta maxima).…”

Partial replacement of fish oil with terrestrial lipid blend and effects on growth performance, body composition, immune parameter and growth‐related genes in yellow drum ( Nibea albiflora )

“…Concomitantly, studies to curtail fish oil consumption in aquaculture with inexpensive and readily available lipid sources that do not compromise fish growth and health have garnered increasing attention (Altundag, Tiril, & Ozdemir, ; Huang et al, ; Peng, Xu, et al, ; Regost, Arzel, Robin, Rosenlund, & Kaushik, ; Turchini, Torstensen, & Ng, ; Zhou et al, ). However, some studies reported that terrestrial lipid sources alter fish feed intake, digestion and metabolism (Huang et al, ), which affect fish growth and flesh quality (Kim et al, ; Zhou et al, ), due to variation in the fatty acid composition between fish oil and terrestrial lipids.…”
