Includes bibliographical references (page 3). "Ovaries were obtained from Pacific cod and English sole from two areas in Hecate Strait for histological examination of the ovarian cycle. Length at 50% maturity was estimated at 55 cm for Pacific cod. Pacific cod were also sampled for fecundity from both areas. Ageing structures were taken from all English sole (otoliths) and from Pacific cod (fin rays) from the northern fecundity sample. The overall length frequency of Pacific cod suggests a weak 1984 year-class and a relatively strong 1985 year-class. Water temperatures during the cruise were warm--8.0 to 8.6°C at 50 m"--Abstract.
