US Aquaculture 10 th 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

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
