What I mean by a “fishery”• A social-ecological system organized around the harvest of wild
marine/aquatic fish or invertebrates for use by humans.

Declining fishing rate and signs of rebuilding
• 7 of 10 regions at or below fishing rate that yields MSY
• Higher fishing rates in Europe• Biomass still low in most regions• Signs of rebuilding in:
– California– Northeast U.S.?– Iceland

A New Consensus
• Overfishing has depleted a significant number of stocks and ecosystems
• Solution: reduce fishing pressure to achieve better economic and ecological outcomes
• New focus on restoring biodiversity, rebuilding fisheries
• High seas and less developed countries remain great challenges

New Jersey Fisheries
• Commercial landings in NJ worth about $150 million per year
• Cape May – Wildwood is the 8th most important fishing port in the U.S. (by value)
• Recreational anglers: 1.2 million in NJ
• Recreational fishing impact: $1.6 billion annually
