| Abstract;A narrow sense of heritability for growth was calculated by factorial mating system in rainbow trout(Oncorhyncus mykiss). The values are 0.030-0.295 for fork length, are 0.013-0.123 for body weight. A broad sense of heritability and degree of fluctuation for growth were calculated using a single pair mating system, picked out from the above factorial mating system. A broad sense of heritability and degree of fluctuation were compared with the narrow sense of heritability. Both heritabilities are very similar at 161 days after hatching. Degree of fluctuation is directly correlated to broad sense of heritability. The results suggested that broad sense of heritability and degree of fluctuation could be useful as genetic variability of growth. (author abst.) |
