Effect of female size on fecundity and egg size in white‐spotted charr: comparison between sea‐run and resident forms

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. ? 1998 The Fisheries Society of the British Isles
