Eggs of Salmo gairdneri, S. trutta, Salvelinus alpinus, S. fontinalis, Hucho hucho and Thymallus thymallus from different localities and populations were reared at several constant temperatures in 274 experiments. Optimum temperatures and ranges over which hatching occurred are given and varied between species. There was an inverse relationship between water temperature (T °C) and both the duration of embryonic development and the length of the hatching period. Quantitative information on the hatching success and hatching times of 30 populations is briefly summarised and discussed. |
