Table S1: Statistical results of the linear model testing the effect of species, sex, and month on the Le Cren condition index. The best model was selected with the AIC as being lme(Le.Cren.index∼Species+Sex+Sampling_Months, random = ∼1|Fish_., data=data). Significant effects are indicated in bold.

Table S2: Statistical results of the linear model testing the effect of species, sex, month on the gonado-somatic index. The best model was selected with the AIC as being lme(GSI∼Species*Sex*Sampling_Months, random = ∼1|Fish_., data = data, na.action=na.omit).

Table S3: Statistical results of the linear model testing the effect of species, sex, month on the neutral/polar lipids ratio. The best model was selected with the AIC as being lme(ratio∼Species*Sex*Sampling_Months*Tissue, random = ∼1|Fish_., data = data, na.action=na.omit).

Table S4: PERMANOVA (Euclidian method performed on centered log data) complete results for comparison in fatty acid percentages among tissues (gonad and muscle), species (S. aurita and S. maderensis), sexes, lipid fraction (polar and neutral), sampling month (January and March) and their interactions.

Table S5: Statistical results of the linear model testing the effect of tissues (gonad and muscle), species, sexes, lipid fraction (polar and neutral), sampling month (January and March) and their interactions on DHA, ARA, and EPA fatty acid concentrations. Lme (Fatty acid∼Species*Sex*Month*Fraction*Tissue, random = ∼1|Individual, data=data). Significant effects are indicated in bold.

Figure S1: Total Length-Weight relationship of Sardinellas. (A) the Sardinella aurita and Sardinella maderensis individuals sampled in this study in January (Jan) and March (Mar); (B) the S. aurita individuals sampled in this study compared to the relationship found by Baldé et al. (2019) for the same species, (C) the S. maderensis individuals sampled in this study compared to the relationship found by Ba et al. (2016) for the same species.
