Effect of pomegranate seed oil on fatty acids composition of Oreochromis niloticus trough supplemented diet

摘要

Several health benefits have been attributed to conjugated linolenic acid isomers (CLnA). In this study, the diet for Nile tilapia was supplied with pomegranate seed oil (at 2.1%) as source of CLnA. The diet was provided to the fish for 15 and 30 days. The punic acid (40.58-53.77 mg g-1 of total lipids) was incorporated into Nile tilapia fillet after 15 and 30 days of experiment, respectively. When compared to the control diet, the level of total saturated fatty acids in fish were slightly increased. No change in the total amount of monounsaturated fatty acid was observed. The pomegranate seed oil diet was effective in the transference of CLnA to Nile tilapia.
