The influence of feed supply time on the fatty acid profile of Nile tilapia (Oreochromis niloticus) fed on a diet enriched with n-3 fatty acids

Incorporation and profile of fatty acids in tilapia fillets (Oreochromis niloticus) fed with tung oil

“…Palmitic acid (16:0) was the saturated fatty acid (SFA) found in the greatest amount, followed by MUFA and PUFA oleic acid (18:1n-9) and linoleic acid (18:2n-6), respectively. The same was observed in Nile tilapia fed modified diets (JUSTI et al, 2003).…”

“…Although the interest of researchers in evaluating the incorporation of different fatty acids into tilapia muscle tissues has resulted in some scientific studies (VISENTAINER et al, 2005;SOUZA et al, 2007;JUSTI et al, 2003;OMENA et al, 2010), the dietary supplementation of these fish with the geometric and positional isomers of octadecatrienoic acid (18:3n-3), also known as conjugated linolenic acid (CLnA) (YANG et al, 2009), has never been evaluated. Some of its isomers have proven biological activity (SEÇKIN et al, 2005;SUZUKI et al, 2001;YASUI et al, 2005).…”

Incorporation of conjugated linoleic acid (CLA) and α-linolenic acid (LNA) in pacu fillets

“…These results can be compared to those obtained by Justi et al (2003) in a study conducted with Nile Tilapia, in which the authors used diets enriched with 3.75% linseed oil and also verified an increase of 290% in the concentration of LNA in the fillets.…”

“…Regarding the amount of PUFA, there was an increase (P<0.05) in all diets, but it was highest in the fish fillets fed diet D. Justi et al (2003) found no difference in the SFA and PUFA concentrations in fillets of Nile Tilapia (Oreochromis niloticus) fed a diet supplemented with linseed.…”

“…Accordingly, the incorporation of linseed oil in fish diet has improved their profile of n-3 fatty acids (Justi et al, 2003;Visentainer et al, 2005).…”
