• Growth rate and age at sexual maturity of Atlantic salmon smoltifying aged one and two years 

      Nævdal, Gunnar; Bjerk, Øyvind; Holm, Marianne; Lerøy, Rita; Møller, Dag (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1979)
      Post-smolt growth rate and age at first maturation are compared for sib groups or population groups of salmon originating from Norwegian rivers and fish farms. Generally, high correlations were found between corresponding ...
    • Individual growth rate and age at first sexual maturity in Atlantic salmon 

      Nævdal, Gunnar; Holm, Marianne; Lerøy, Rita; Møller, Dag (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1978)
      Growth rates and possible connection between growth rate and age at maturation were studied on individually tagged salmon originating from different river populations. Great variations in growth rate and in age at first ...
    • Individual growth rate and age at sexual maturity in rainbow trout 

      Nævdal, Gunnar; Holm, Marianne; Lerøy, Rita; Møller, Dag (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1979)
      Growth rate possible connection between growth rate and age at sexual maturity were studied on individually tagged rainbow trout from different sib groups. Considerable variation in growth rate and age at first sexual ...
    • Sources of variation in weight and length of Atlantic salmon 

      Nævdal, Gunnar; Lerøy, Rita; Møller, Dag (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1983)
      Variances of weight and total length of four year classes of farmed Atlantic salmon after two years in the sea were distributed on strain, family, maturing/immature (after two winters) and sex. Higllly significant ...
    • Variation in growth rate and age at first maturation in rainbow trout 

      Nævdal, Gunnar; Lerøy, Rita; Møller, Dag (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1981)
      The present report is an account of the main results of a series of experiments on selective breeding of rainbow trout. The experiments started in 1972, but were discontinued in 1979 because IPN virus was detected in the ...
