Dietary lipid and palm oil source affects growth, fatty acid composition and muscle α-tocopherol concentration of African catfish, Clarias gariepinus

Differential Effects of Dietary Lipids on Growth Performance, Digestibility, Fatty Acid Composition and Histology of African Catfish (Heterobranchus longifilis) Fingerlings

“…This finding is consistent with previous studies showing successful partial or total replacement of dietary fish oil with vegetable oil in African catfish [25][26][27], rainbow trout [28], sharpsnout sea bream [29] and Atlantic salmon [30,31] without showing any negative impact on growth.…”

“…An increase in DHA levels observed in fish fatty acid composition with respect to feed fatty acid composition was observed. Similar results were observed in sharpsnout seabream (Piedecausa et al, 2007) brown trout (Arslan et al, 2012), sea bass (Mourente et al, 2005;Eroldoğan et al, 2012;Yılmaz and Eroldoğan, 2015), rainbow trout (Caballero et al, 2002), African catfish (Ng et al, 2003) and turbot (Bell et al, 1994;Regost et al, 2003). The reason of the deposition of DHA is prefentially retained in phospholipid fraction of lipid to maintain cell membran structure (Bell et al, 2003).…”

“…In our study, in vegetable oil groups, EPA, DHA and arachidonic acid (ARA) levels were found to be lower than the FO group. The similar observations have been reported in different fish species such as Atlantic salmon (Bell et al, , 2003 trout (Caballero et al, 2002), African catfish (Ng et al, 2003), turbot (Regost et al, 2003), sea bass (Mourente et al, 2005), sea bream and sharpsnout seabream (Piedecausa et al, 2007). Dietary fatty acids influence the fish body fatty acid composition (Turchini et al, 2009;Eroldoğan et al, 2012).…”

A Complementary Biodiesel Blend from Soapnut Oil and Free Fatty Acids

“…In some cases, FFAs are byproducts of the food-processing industry, such as the edible palm oil-based oleochemical industry, which releases 4%-8% of the total fatty acids as FFAs in crude palm oil during the physical refining process [10,11]. By converting the FFAs into biodiesel, a profitable system could be established to provide economic opportunities and benefit the environment without competing with the edible-oil market [12].…”
