Salmon Carcass Tossing
Why toss salmon carcasses?

It helps salmon.
Why toss salmon carcasses?
It helps other wildlife, too!
Why toss salmon carcasses?

Why toss salmon carcasses?

Salmon connect people
with our natural resources.
Wa He Lut Indian School
10 years of Carcass Tossing
(1999-2013---no fish tossed in 2008/09)

106 tons of rotten salmon tossed

293,200 lbs!
About ...
30 Orca Whales (9,600lbs each)
300,000 lb jet
Timing
*above Centralia Dam
What To Wear:
Rain gear and rubber boots are
recommended!
Dress in layers to keep warm.
Bring a plastic bag to store smell...
On your field
experience….
…let’s look for early
signs of SPRING!

  • Eggs – up to 3,000 per redd….less than 5% will survive to adulthood
  • Alevins remain in the gravel for protection, feeding off of the yolk sac attached to their belly
  • Salmon need clean, clear, cold abundant fresh water and gravel of a specific size
  • Provide shade, produce oxygen, food web input, prevent erosion and input LWD
  • LWD
  • Estuary – where fresh and saltwater mix
    Gives a saline gradient for adjusting to saltwater, many niches and lots of food
    How big are these “smolts”?
  • 3-5+ years in the open ocean
  • Mostly eating krill and other small crustaceans (which gives them the pink color in their flesh) AND where they grow most of their biomass
  • Silver coloration in ocean for camouflage
    Dark on dorsal side, so looking down blend with depth
    Bright on ventral (belly) side, so looking up, blend with light
  • Coloration changes to re-camouflage with river/stream ecosystem
    Return to same stream where they were born
  • Carcass = important source of MARINE DERIVED NUTRIENTS
  • Redd – these eggs, after hatching, will need nutrients!
  • Macros are are also highly effected..
    They provide the insects with valuable marine derived nutrients.
    These insects are an important part of the food web and can also indicate the health and efficiency of rivers and streams.
  • A few of the species effected by the presence of salmon and marine derived nutrients!
  • 137 vertebrate species depend on salmon, a keystone species for our region
  • Extra nitrogen promotes tree growth, assisting in the reversal of the effects of global climate change.
    A study in AK showed up to 17% of nitrogen in streamside plants was marine derived
