Abstract
We investigated the independent effects of age at smolting and body condition at the time of spawning on egg production by female Atlantic salmon (Salmo salar). For a given body size, female salmon that had smolted as juveniles after 2 years in fresh water produced smaller, more numerous eggs than females that smolted 1 year later. Furthermore, fecundity (but not egg size) was related positively to maternal body condition at spawning. Given that age at smolting is closely related to juvenile growth rate; results from this study suggest that conditions experienced by female Atlantic salmon during both early life and adulthood have implications for the size and number of eggs that they produce.
