GOOD JOBS - RESPONSIBLE STEWARDSHIP - HEALTHY FOOD
HOME: A RELATIVELY SMALL LIFEBOAT IN A HOSTILE ENVIRONMENT
SINCE 1950 WE HAVE CONSUMED 2X THE RESOURCES THAN ALL PRIOR HISTORY COMBINED

NATIONAL STATUS AND TRENDS
• ≈94% OF SEAFOOD IMPORTED
• <2% OF IMPORTS INSPECTED (CONTAMINANTS, RESIDUES)
• ≈59% OF ALL SEAFOOD CONSUMED IN US IS FARMED
• CONTRIBUTES $15.6 BILLION TO U.S. TRADE DEFICIT
• US AQUACULTURE >$1.5 BILLION (FARM GATE)
• ≈4200 FARMS (MOST FRESHWATER)
