Demographic Consequences of Precocious Maturation of Atlantic Salmon ( Salmo salar)
Detailed records of outgoing smolts of Atlantic salmon (Salmo salar) and estimates of the parr population that produced them were used to study the demographic conequences of male precocious sexual maturation in southwest Newfoundland. Approximately 80% of males matured precociously in the stream. A...
