  2. Why participate in Ocean Sciences Bowl? #5: Win prizes and scholarships #4: Get college credit • #3: Learn about the oceans • Helps you choose your major in college • Gives you a broader perspective of the world • Prepares you for a career in the marine sciences and other fields • #2: It’s fun • Travel to distant states for free, such as Alaska • Top 4 at nationals go to foreign countries, such as Costa Rica #1: Mr. Hames is the coach

  3. What is aquaculture? • Aquaculture is the cultivation of aquatic organisms in a controlled environment for harvest or release into the wild • Mariculture: marine aquaculture • Ocean ranching: rearing in hatcheries, then releasing

  4. US Aquaculture • 10th in total production in 2004 (UN FAO) • #1 is Norway • 20% in US is marine

  5. Types of Aquaculture • Open water cages • Recirculating closed-water systems • Ponds: ancient Chinese tradition • Raceway: constant linear flow

  6. Importance and Problems • Feedstocks are unsustainably fished • Fish are a major source of protein around the world • Salmon oil in biodiesel production • Overfishing: • 52% of fish stocks are fully exploited • 20% are moderately exploited • 17% are overexploited • 7% are depleted • 1% is recovering from depletion • 80% of seafood is imported into US

  7. History of Aquaculture • China & Egypt: centuries before Year Zero • Carp in ponds • Romans: oysters • 1733: German successfully fertilized eggs and raised the fish • NOAA’s Aquaculture Program was revived in 2004
