| Summary: | The following paper gives a detailed description of the oogenesis cycle for the European Plaice (<i>Pleuronectes platessa</i>), from oogonia to post-ovulatory follicle, including ovarian follicle and <i>zona pellucida</i> sizes. Noteworthy particularities were the difficulty in identifying cortical alveoli due to their very small size. Quantitative histology (stereology) on histological slides was used to determine a first size at maturity for females from the English Channel, which was found to be smaller compared to the literature (19 cm). Stereology also determined a first spawning event starting in January, with a peak in February and ongoing until March. Moreover, the use of stereology showed misclassifications for individuals categorized into a maturity phase using a macroscopic visual method. Misclassifications were found with individuals that had spawned (D) but were put under the immature (A) phase, and individuals in development (B) classified under D. |
