Mirza, R.S. and Chivers, D.P. and Godin, J-GJ. (2001) Brook charr alevins alter timing of nest emergence in response to chemical cues from fish predators. Journal of Chemical Ecology [J. Chem. Ecol.]., pp. 1775-1786
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 |
