EPA, DHA, cholesterol and phospholipid content were determined in the Trachinus draco, Trigla lyra and (wild and cultured) Pagrus pagrus muscles. The EPA and DHA levels - as determined by GC-GC/MS - in the cultured P. pagrus muscles (233.20 +/- 16.3 and 399.39 +/- 31.1 mg/100g of the wet tissue respectively) were found to be significantly higher compared to the ones in the wild P. pagrus, T. draco and T. lyra (26.31 +/- 2.26, 158.24 +/- 10.92 mg/100 g, 28.65 +/- 1.68, 155.97 +/- 2.63 mg/100 g 35.66 +/- 0.66 and 102.52 +/- 1.71 mg/100 g of the wet muscles respectively). The amounts of cholesterol (determined by GC on a capillary column) and phospholipids in the cultured P. pagrus muscles were significantly higher (149.3 mg/100 g and 0.80 g/100 g of the wet tissue respectively) compared to the ones in the wild P. pagrus (8.73 mg/100 g and 0.40 g/100 g), T. draco (41.72 mg/100 g and 0.59 g/100 g) and T. lyra muscles (38.63 mg/100 g and 0.40 g/100 g of the wet tissue respectively). The highest DHA/EPA and omega-3/omega-6 ratios were 6.00 and 5.93 in wild P. pagrus and T. draco muscles respectively, while the lowest in cultured P. pagrus (1.71 and 1.48 respectively).
