Why do we
care about fish?

B/yr!
>> 400 million people depend on fish for livelihood, protein, minerals.
• In 2011, consumption hit a record high of 37 pounds / person / yr. • On average, people eat 4x more than in 1950.

Ta ke h o m e m e s s a g e s • Fish are not (just) food! • We know a fraction of what is going on under the surface • What we do know is that they can be complex, clever creatures • And they are seriously
threatened (Tragedy of the Commons)
• Salmon in particular (Hatcheries, Habitat, Hydroelectricity, Harvest) • Learn & think about our food & environment • Pressurize politicians to make
• Otoliths are awesome
tough decisions
