Effect of different levels of highly unsaturated fatty acids on growth and fatty acid composition of juvenile gilthead bream (Sparus aurata)

Effects of olive pomace and olive pomace oil on growth performance, fatty acid composition and cardio protective properties of gilthead sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax)

“…According to the literature, the biological demand of gilthead sea bream and sea bass is at least 0.9% and 0.7% of the diet, respectively (Ibeas et al, 1994;Kalogeropoulos et al, 1992, Skalli & Robin, 2004. In the present study, the x-3 HUFA content of experimental diets meet the theoretical values of the examined species requirements in these FAs (Table 4).…”

“…According to the literature, the minimum requirement of juvenile gilthead bream for EPA and DHA is around 0.9% of the diet (Kalogeropoulos et al, 1992), while the optimum x-3 HUFA requirement is about 1.9% of the dry diet (Ibeas, Izquierdo, & Lorenzo, 1994). Regarding the juvenile sea bass the requirement for growth of x-3 HUFA is at least 0.7% of the dry diet (Skalli & Robin, 2004).…”

Dietary DHA/EPA ratio affects growth, tissue fatty acid profiles and expression of genes involved in lipid metabolism in mud crab Scylla paramamosain supplied with appropriate n-3 LC-PUFA at two lipid levels

“…Similar studies have been reported in other species. The n-3 LC-PUFA requirements of juvenile gilthead bream (S. aurata) were estimated to be 0.9% of diet when the DHA/EPA ratio was 1.0 at a dietary lipid level of 13% (Kalogeropoulos et al, 1992), whereas it was 1.9% when the DHA/EPA ratio was 0.5 and dietary lipid level was 8% (Ibeas et al, 1994). Another study showed that n-3 LC-PUFA requirement was about 3% when sea bream fed a diet with a DHA/EPA ratio of 1.0 and 22% dietary lipid (Houston et al, 2017).…”

Hepatic steatosis in artificially fed marine teleosts

“…The importance of a correct n-3/n-6 PUFA ratio for freshwater teleost growth (Cowey & Sargent 1979) is well known, and most commercial fish diets have taken into account the importance of optimizing this ratio. However, marine teleosts seem to have a very specific requirement for the fatty acids which is fully satisfied only by natural diets (Cowey & Sargent 1979;Ibeas, Izquierdo & Lorenzo 1994). We have studied this by examining the appearance and disappearance of steatosis under different experimental conditions.…”
