Temporal and Spatial Variation in Fecundity of Atlantic Cod ( Gadus morhua ) in Newfoundland Waters

Abstract

Fecundity of Atlantic cod from inshore bays of Newfoundland and from St. Pierre Bank off the south coast of Newfoundland is described in relation to fish length and age. Fecundity-length relationships are compared to published results for offshore areas. Annual differences were noted within areas in the numbers of eggs produced by length and age but not in the rate of increase in egg production with increase in length or age. Differences were noted among areas in the rate of increase in egg production with increase in length and these are discussed in relation to environmental conditions.
