What is Evaluation of quantitative importance of egg lipids and fatty acids during embryos and larvae development in marine pelagophil teleosts: with an emphasis on Dentex dentex about?

## Abstract Quantitative compositin of __Dentex dentex__ eggs lipid classes (LCs) and fatty acid (FA)s were measured and correlated to embryo and larva viability parameters (egg buoyancy, floating rate (FR), hatching rate, HR and survival rate, SR, at 0–5 days post hatch, dph) through 43 formulated models (38 using FAs, as independent variable, [__R__^2^=0.641–0.859] and 5 using LC [__R__^2^=0.459–0.739]). The sphingomyelin, phosphatidylcholine and 20:2(__n__–6) were significantly correlated with FR; phosphatidylserine+phosphatidylinositol with SR at 1 dph; steryl ester+waxes/triacylglycerol with HR and SR at 0 dph; 14:0 with SR at 1–5 dph; 18:1(__n__–9), ∑18:1, 20:5(__n__–3)/20:4(__n__–6), ∑monounsaturated FAs (MUFAs), 20:5(__n__–3), 22:6(__n__–3)/20:5(__n__–3) and 18:3(__n__–3) with SR at 2–5 dph; 20:5(__n__–3)+20:4(__n__–6) with FR and SR at 2–5 dph. It was also found that a 14:0, 18:1(__n__–9), ∑MUFA, 18:2(__n__–6), 18:3(__n__–3), 20:5(__n__–3), 22:6(__n__–3)/20:5(__n__–3) and 20:5(__n__–3)/20:4(__n__–6) equal to 3.3, 16.5, 32.5, 9, 1.3, 8, 1.5 and 7, respectively, perhaps can provide a SR at 3 and 5 dph of >70%. The results indicated the importance of the egg LCs and FAs quant
