Overfishing Group #: (Presenters names)
Why is overfishing a problem? No time for recovery Fish populations collapsing Supply limited (Koster, 2007)
U.S. seafood trade deficit = $8 billion discard rate in U.S. = 21.7% 70% of fish caught beyond capacity Data About Extent of Problem
Cause of Overfishing mainly over-exploitation (Jeantheau, 2005)
Impact on Environment Low growth rates Severe biomass levels Changes in species composition & biodiversity Extreme changes to the ocean: 1. Degradation of reefs 2. Destruction to bottom grasses
Impact on Human Health Prevents heart disease and strokes Poverty countries depend on fish Omega-3 fatty acids Overfishing = all of the above gone
Impact on Economy Industry earns $50 billion per year Huge industry; must be maintained As technology improves, we fish more. Fish population goes down, less revenue. Prices rise and technology is developed to meet demand.
Data on Impact coral reefs being destroyed population decreasing fish prices increase
Strategies for Addressing the Problem Promote fish farming Allow recovery-rotating fishing grounds Passing laws addressing issue (Miller & Levine, 2003)
