### *2.1. Biochemical Composition of Ovaries*

The water content of *R. pulmo* ovaries was 93.7 ± 1.9% (Figure 1A). After dehydration, organic matter was the main part (60.43 ± 10.14%) of ovary dry weight (Figure 1B). The organic residue of the ovaries was mainly composed of proteins (761.76 ± 25.11 μg mg<sup>−</sup><sup>1</sup> OM), lipids (192.17 ± 10.56 μg mg<sup>−</sup><sup>1</sup> OM), and carbohydrates (59.66 ± 2.72 μg mg<sup>−</sup><sup>1</sup> OM); Figure 1B).

Among lipids, the mean triglyceride and cholesterol concentrations were 0.12 ± 0.008 mg/mL and 0.24 ± 0.0023 mg/mL, respectively.
