Solving the mystery

Now that you have learned about salmon, climate change, the Fraser river, their amazing upriver migration, how gases in water respond to temperature and salinity, and the physiology of respiration, circulation and exercise in salmon - and how these systems are affected by temperature - you are ready to solve the mystery of the disappearing salmon!

The assignment

  • Review what you learned in Acitivities 1-8

  • What hypotheses can you propose for the salmon disappearances?

  • Does recent data support your hypotheses or not?

  • Why are the Fraser fish vanishing?




Let's investigate these questions in the lesson that follows >>
