Abstract:
The relationships between fecundity, egg size and female size of sea-run form were compared with resident form, using white-spotted charr, Salvelinus leucomaenis. Both fecundity and egg size increase with female size. However, the relationship between egg size and female size differed significantly between the resident and sea-run forms. Egg sizes of sea-run and resident were similar even though sea-run fish were much larger.
