Total lipids were stored in chloroform/methanol (2:1 , 10 mg ml’ 1 ) at -20°C until final analysis.
  • Fatty acid methyl esters were prepared from total lipid by acid-catalysed transesterification using 2 ml of 1 % H2SO4 in methanol plus 1 ml toluene, and FAME were then extracted and purified. FAME were separated and quantified by gas-liquid chromatography (Fisons GC8600, Carlo Erba, Milan, Italy) using a 30 m x 0.32 mm capillary column (CP wax 52CB; Chrompak, London, U.K) utilizing on-column injection at 50°C and flame ionization detection at 250°C.
  • Hydrogen was used as carrier gas (2.0 ml min -1 constant flow rate), injection was on-column and temperature programming was from 50°C to 180°C at 40°C min -1 and then to 225°C at 2°C min -1 .

  • the fish’s fillet fatty acid profile was significantly affected by the tested feed additives A (diets A1.0 and A1.5) and B in a manner that does not reflect the diet’s fatty acid composition (Table 6). Some unexpected results were observed in SFA levels (little affected by either fish feed or additive supplementation), but the main effects concerned the n-3 and n-6 PLIFA profile.
  • both additives clearly modified the PLIFA profile of lipids in fish fillet when added to the negative control (NC) feed.
  • NC negative control
  • the additives enabled offsetting the effects of mammal’s fat inclusion and approximating the fillet lipid profile to that of fish fed the positive control (PC) feed containing 100% fish oil.
  • partial replacement of fish oil by mammal’s fat in the NC feed of the present invention caused a significant increase in the levels of C18 PLIFA, both LA and ALA, in total lipids and a significant decrease in LC-PUFA, including ARA, EPA, DPA and DHA, in total lipids compared to the PC treatment.
  • feed additives A and B affected the balance between n-3 and n-6 in the lipids of the fish fillet a positive way, from both the fish’s and consumer’s health point of view.
  • fillet lipids of fish fed the additive-supplemented feeds had enhanced levels of total n-3 PUFA and lowered total n-6 PUFA, and therefore a higher n-3/n-6 PUFA ratio, compared to fillets of fish fed the NC feed.
  • the supplementation of a fish-oil reduced fish feed with additives A and B allowed bringing the balance between n-3 and n-6 PUFA in the fish fillet lipids closer to that found in the PC treatment (see Table 6, Fig. 3).
