Table 2. Statistical table of the integrated biochemical condition of female swordfish.

Results of the two-way ANOVA assessing differences in the contents of lipids (in mg and %), proteins (in mg and %), glucose (in mg and %) and energy (in J mg−1) in the gonads of female Xiphias gladius, considering the sampled season (“Season”) and female size ranges (“Size”) as fixed factors.
