  • 8. jschmied©2014 In the end of life comes a new beginning! http://www.mvihes.bc.ca/images/ERWRP/circle4.jpg Females use their tails to create a low pressure zone to move rocks & make the redd. Redds are about 18 – 36” deep depending on the salmon species Salmon Redd http://www.des.water.ca.gov/images/FRP/Steelhead_Redd1.jpg

A new part of the redd is dug just downstream to keep silt off the older eggs
  • 10. jschmied©2014 o o Total amount of degrees above freezing (energy) young salmon accumulate over time. Used to predict time to hatch, emerge from redd, etc. ATU = Day’s H2O temp in F° – 32F = ____ ATU Ex: 39F° - 32F°= 7 ATU Using 7 ATU/Day: COHO SALMON Atu’s in F° Number Days to: To eyed stage 220 31.5 To hatch 400-500 57 - 71 To emergence 700-800 100 - 114
  • 11. Mud and Sand cover the salmon eggs. Toxic run off from streets & lawn chemicals. Floods disturb the redd, leaving eggs exposed to predators. The Streets become small streams. Non permeable jschmied©2014
