Includes bibliographical references (pages 6-7). "Pacific cod and English sole were sampled for length, maturity, body and ovary weight and fecundity (Pacific cod) and histology (English sole). Length at 50% maturity for Pacific cod decreased from north to south in Hecate Strait: Two Peaks - 53.1 cm; Reef Island - 40.3 cm. The same trend was observed for English sole: Two Peaks - 36.1 cm; Reef Island - 32.5 cm. Ovary weight vs fish weight showed a linear relationship for Pacific cod and a curvilinear one for English sole. The gonosomatic index (GSI) for Pacific cod varied from 3.59 to 22.93 and for English sole from 0.30 to 1.65. The much higher GSI for Pacific cod reflects the fact that this cruise took place during the spawning season for cod. Length-frequency data confirmed the presence of a strong 1985 year-class of Pacific cod now present as four-year-old fish"--Abstract, page iii. Includes abstracts in English and French.
