  1. FISH STORY Kate Stoeckle and Louisa Strauss Johns Hopkins University Presented at AAAS Annual Meeting, San Diego, CA, February 19, 2010

  2. Trinity School, NYC March 2007 11th grade Can we identify sushi with DNA barcoding?

  3. What we did 1. Shop (and eat) 2. Sample  3. Document 

  4. 4. Sequence 5. Match to database

  5. What we found -One-quarter of samples mislabeled, all as more expensive or more desirable fish -Mislabeling in 6/10 grocery stores/ fish markets and 2/3 restaurants

  6. For example

  7. Diverse items mislabeled • Lavender Jobfish, Slender Pinjalo (SE Asia), Acadian Redfish (N Atlantic), Nile Perch (Africa) sold as Red Snapper (Caribbean) • Caribbean Spotted Goatfish sold as “Mediterranean Red Mullet” • White Bass (farmed freshwater fish) sold as “Sea Bass” • Smelt Roe sold as “Flying Fish Roe”

  8. For example Label: Red Snapper DNA ID: Nile Perch FishBase: John Casselman Range map: FishBase

  9. What we wrote Our results in scientific report

  10. Our study attracts interest Page 1

  11. Kate Stoeckle and Louisa Strauss August 22, 2008

  12. Korean Daily News CBS Early Show >380 tv, radio, print, and online media reports in 10 languages and 34 countries Press named it “Sushi-gate”

  13. Our study inspired others A DNA Barcoding Analysis of Commercially-Sold Fish Thomas Jefferson High School, Alexandria, VA June 2009

  14. DNA Barcoding + students = • Learn science • Make discoveries • Have fun

  15. Acknowledgments
