Description: Salmonid fishes differ in degree of anadromy, age of maturation, frequency of reproduction, body size and fecundity, sexual dimorphism, breeding season, morphology, and, to a lesser degree, parental care. Patterns of variation and their possible significance for ecology and evolution and for resource management are the focus of this review.

Keywords: Salmon, char, Oncorhynchus, Salmo, Salvelinus, life history, sexual dimor-phism, age of maturation, semelparity, anadromy, phenology, phenotypic variation, parental care, speciation
