| 内容記述 | The variations in hatchability and hatching time in coho salmon were analyzed. Nine males were mated with thirty females according to a hierarchial mating system. Eggs of twenty-one lots which had over 20% hatchability were used for examination of hatching time and duration of hatching. Parental stock used had been imported from Oregon, U.S.A. as eyed eggs and raised at a freshwater fish farm in Japan. Hatchability varied from 0 to 91.3% with mean value of 46.2%, being under 10% in nine out of thirty lots. The size of female, mean egg weight, egg density in iucubator and position of incubator showed no significant effect on hatchability. At least one lot within a sire had over 50% hatchability. A great fluctuation was observed in hatching time even in the same lot and duration of hatching ranged 6 to 21 days. Mean hatching time and mean degree-days (Centigrade) were in the ranges of 65 to 69 days and 476 to 516, respectively. The analysis of variance of half-sib showed that differences in hatching time among sires and among dams within sires were significant at 1% level. Based on the sire and the dam component, heritabilities for hatching time were estimated to be 0.261 and 0.511 respectively. These values suggest that additive genetic variance forms about one-fourth of phenotypic variance and maternal effect is 0.063. | |||||||
