Ocean Resources are available to everyone.

Even though you may know that what you want to do is not good for future generations…….you are inclined to do so because it is in your own best interest in the short term!

A keystone species = A species that has an unusually large effect on the rest of its environment comparedto its abundance.[1]

The importance of salmon runs to plants & animals in the entire NW food chain is enormous. For food – predators & scavengers (over 40 species) For nutrients – adds Nitrogen/Phosphates for growth of streamside plants, cools H2O, prevent erosion… For Income & Jobs - $1.5 B 60K jobs for Fishermen, Suppliers, truckers, restaurants, etc

Salmon ReddSalmon Redd


Females use their tails to create a low pressure zone to move

6-7”rocks & make their redds (nest).

Redds are about 18 – 36” deep & 25-30’ long depending on the

salmon species

Salmon mating on Salmon ReddSalmon mating on Salmon Redd


Eggs from each mating are covered up by the female. A new part

of the redd is dug just downstreamKeeping silt off the older eggs

o Total amount of degrees above freezing (energy) young salmon accumulate over time.

o Predicts time to hatch, emerge from redd, etc. ATU = Day’s H2O temp 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 31.5To hatch 400-500 57 - 71To emergence 700-800 100 - 114


Mud and Sand cover the salmon eggs.

Toxic run off from streets & lawn chemicals. Floods disturb the redd,leaving eggs exposed to predators.


In rainstorms, the streets become small streams. Non permeable
