  3. If there’s no fish, why didn’t anyone know? • Researchers carefully monitor catches and conduct their own population estimates. • Watch for reasons why they missed warning signs that the oceans were being over-harvested

  4. The problem with the China Data

  5. Fishing down the food web 6 5 Trophic level 4 3 2

  6. Decrease in trophic level of catch

  7. This is happening worldwide

  8. Also catching smaller fish – decrease in max length

  9. What’s the problem? • Energy now available to ‘undesirable’ species • Huge increases in jellyfish • Bacteria • We are already eating what was once considered undesirable fish • Lobster and other crustaceans • Menhaden and shad • What is the future of our food?
