Effect of two temperature regimes from a deep and a surface water release on early development of salmonids
Abstract In order to test the effect of regulated water temperature on the development of eggs and alevins of three salmonid species, deep and surface water from an oligotrophic lake was pumped into a hatchery. Atlantic salmon ( Salmo salar ) clearly needed the highest number of degree‐days to reach...
