| Species | Development state | Trait | Primary Data | Secondary Data |
| Thymallus arcticus | Egg | Incubation time | Most eggs hatched after 14-19 days after fertilization | 16.5 days |
| Thymallus arcticus | Egg | Temperature for incubation | The eggs initially were incubated in jars with springwater 8.0 ± .°C | 8.0 °C |
| Thymallus arcticus | Larvae | Temperature during larval development | Rearing temperature, controlled by mixing cold and warm sprinwater, was increased to 10.0 ± 1.0°C after hatching was completed | 10.0 °C |
| Thymallus arcticus | Larvae | Full yolk-sac resorption | About 100 [The young developed in the trays until most were free-swimming (24-29 days after fertilization) i.e. 10 days at 10°C] | 26.5 °C * day |
| Thymallus arcticus | Spawning conditions | Spawning season | May and June | ['May', 'June'] |
| Thymallus arcticus | Spawning conditions | Spawning water type | Spawning in lake Agnes occurs primarily in the largest inlet stream, with minor spawning activity in two smaller inlet streams an possibly along shawllow shoreline areas. Spawning in Deer Lake appears to occur only in the outlet stream | Stagnant water |
