Includes bibliographical references (pages 4-5). "We collected ovaries from mature English sole in Hecate Strait from 1986-1990. We prepared sections from these for microscopic examination. We observed six distinct histological stages of oocytes, characterized by size and morphology, over an annual cycle. We relate these to macroscopic maturity stages previously described for Pacific coast flatfish species. The microscopic stages represent the sequence of biological events occurring in oogenesis; (production of primary germ cells, mitosis, vacuolization, deposition of yolk, hydration/ovulation, and atresia). We present photomicrograph examples of the different stages"--Abstract, page iii. Includes abstracts in English and French. Parophrys vetulus British Columbia Hecate Strait Histology.
