Plasma 11-ketotestosterone in Individual Age 1+ Spring Chinook Salmon Juvenile Males Accurately Predicts Age 2 Maturation Status
High rates of precocious male maturation of spring Chinook Salmon Oncorhynchus tshawytscha as two-year old minijacks have been observed in Columbia River Basin hatchery programs. Previously, minijack rates have been assessed by lethal sampling during the spring prior to release of the age...
