5203 |a"The spawning season of Pacific cod in British Columbia is primarily January-March, based on 46,106 trawl-caught specimens sampled during 1976-85 at processing plants. Gonad development for both sexes was similar among four areas, but occurred later in the northernmost area (north Hecate Strait). Spawning was apparently determinate and essentially complete by May in north Hecate Strait, and by April elsewhere. Considerable variability was found among hauls and among years within months. A maximum likelihood technique used to fit a curve to the proportion spawned by day of year showed that there was no overlap among the four areas in parameters which describe the rate and timing of the point at which 50% had spawned. Elsewhere in the north Pacific Ocean, cod spawning was also determinate, the season was relatively short and only slightly later in the higher latitudes. In contrast, Atlantic cod are batch spawners, and the seasons are protracted in all areas"--Abstract, page iii.
