| Species | Development state | Trait | Primary Data | Secondary Data |
| Oncorhynchus gorbuscha | Egg | Temperature for incubation | Could tolerate a temperature of 0.5 if previously incubated at 5.5°C [Both chinook and pink salmon eggs could tolerate temperatures as low as 33°F for long periods if the intial incubating temperature had been above 42°F]] | 0.5 °C |
| Oncorhynchus nerka | Egg | Temperature for incubation | Lower limit: 4.4-5.8°C and upper limit 12.7-14.1°C [The lower temperature for the normal devlopment was established between 40 and 42.5°F. The upper threshold temperature occurred between 55 and 57.5°F] | 5.1 °C |
| Oncorhynchus tshawytscha | Egg | Temperature for incubation | Could tolerate a temperature of 0.5 if previously incubated at 5.5°C [Both chinook and pink salmon eggs could tolerate temperatures as low as 33°F for long periods if the intial incubating temperature had been above 42°F]] | 0.5 °C |
