Associated characteristics


Species Development state Trait Primary Data Secondary Data
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
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 Spawning conditions Spawning season May and June ['May', 'June']
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
