Associated characteristics

Species Development state Trait Primary Data Secondary Data
Salvelinus fontinalis Egg Incubation time 75 days at 9.4°C until emergence 75.0 days
Salvelinus fontinalis Egg Temperature for incubation 9.4 ± 0.19 9.4 °C
Salvelinus fontinalis Larvae Larvae behaviour Alevins emerge from the redd after absorbing most of their yolk sac and then rest on the substrate outside the redd reabsorbing of the yolk sac before dispersing in the stream or the lake Demersal
Salvelinus fontinalis Larvae Reaction to light Emergence from gravel nests in salmonids is largely nocturnal Photopositive
Salvelinus fontinalis Spawning conditions Spawning substrate Gravels Lithophils
Salvelinus fontinalis Spawning conditions Spawning site preparation Lay their eggs in gravel nests called redds Susbtrate chooser
Salvelinus fontinalis Spawning conditions Parental care The nests are not defended for extended periods No care
