在挪威开始养殖大西洋鲑鱼后不久，1971年开始进行选择实验。在4年的时间里，亲鱼大西洋鲑鱼在41个不同的河流和地方进行了采样，导致四个人口。在形成基础群体（第0代）时，在品系内进行交配以产生全同胞和半同胞家系。在后代中，交配是在品系内和品系之间进行的。对前三代选择的数据进行了分析，以研究这四个群体的遗传起源。每个种群中有一到三个菌株占主导地位。强调了选择性育种在鱼类养殖中的重要性。
Soon after farming of Atlantic salmon began in Norway, a selection experiment was started in 1971. Over a 4-year period, broodstock of Atlantic salmon were sampled in 41 different rivers and localities resulting in four populations. In forming the base population (generation 0), mating was done within strains to produce full- and half-sib families. In later generations mating was done both within and between strains. Data from the first three generations of selection have been analysed to study the genetic origin of the four populations. One to three strains dominate each population. The importance of selective breeding in fish farming is stressed.
