Jensen, A.J. and Johnsen, B.O. and Heggberget, T.G. (1991) Initial feeding time of Atlantic salmon, Salmo salar, alevins compared to river flow and water temperature in Norwegian streams. Env. Biol. Fish., pp.
|Species||Development state||Trait||Primary Data||Secondary Data|
|Salmo salar||Egg||Temperature for incubation||The peak of hatching was estimated to take place between April and 10 June in the ten rivers studied, at a water temperature of 4.56.8°C||10.0 °C|
|Salmo salar||Larvae||Temperature during larval development||The water at peak intial feeding waried from 8°C in the river Stryneelva to 13°C in the rivers Drammenselva and Imsa. In the other rivers the temperature at peak initial feeding was 9-12°C||10.5 °C|
|Salmo salar||Spawning conditions||Spawning period duration||The peak spawning took place between 18 October and 10 January in the ten rivers, and usually lasted for five to ten days in each river. The duration of the entire spawning perdio lasted from 17 days in the river Numedalslagen to 56 days in river Stryneelva||18.0 weeks|
