5203 |a"Fecundity was determined for 350 Pacific cod from the west coast of Vancouver Island (LaPerouse area) and Hecate Strait over five years, 1986-90. There was little variation by year, geographic area or temperature and no significant difference from similar work done about 25 years earlier. Counts ranged from 0.228 to 5.67 million oocytes for fish ranging in length from 40 to 89 cm. Relationships were determined for fecundity on fish length and weight. The process of hydration was found to greatly affect the number of oocytes per mg, and the percent dry weight vs fish length and ovary weight vs fish weight relationships. The generally smaller oocytes found in smaller fish suggests that either smaller fish release smaller oocytes, or that they possibly spawn later, allowing more time for oocyte growth"--Abstract, page iii.
