Transcript of Sustainable Fisheries
Exploitation Gained recognition in the 1800s when sailors devastated the whale population for blubber, which had widely been used as lamp oil. Industrial fishing has reduced the number of large ocean fish to just 10 percent of their pre-industrial population. Even in the 21st century, several notable fisheries remain in danger of destruction... Fish factories can harvest up to a 100 tons of fish in a single hour and can stay at sea for up to 6 weeks. "Removing fish from the sea more rapidly than populations can reproduce." The Big Fish Why does it matter? What can you do? You might not be aware... But over 71% of the globe has been forced into catastrophic changes... International efforts to raise the affordability and availability of protein-rich foods led to a rise in industrial fishing operations. The 19th Century The 20th Century Developing Years From as early as the 11th century, the depletion of fisheries led to the exploration for unspoilt areas -- from Europe to the Americas, the North Atlantic to the Pacific. By 1989, the fishing industry had removed around 90 million metric tons of catch The Problem
Today 30% of fish stocks are considered over-exploited. 50% are considered fully-exploited, in imminent danger of being over-exploited and at the point of collapse. Fishing Down the Food Web "Having depleted the large predatory fish on top of the food web, we turn to increasingly smaller species, finally ending up with previously spurned small fish and invertebrates." SUPPORT SUSTAINABLY Conservation is painless and simple: East Atlantic

Fishery will fail within the next decade unless illegal practices can be stopped. Targeted by commercial and private sectors, making regulations difficult. Attempted regulations have led to a "derby mentality" and an increase in discarded fish. Low volume of fisheries, but almost no government control Economics Culture And it's surprisingly straightforward... Would help sustain fishery products, which are the most extensively traded agricultural commodity. Help prevent unemployment Sustainable fisheries can create an economic surplus and be a driver of economic growth Plans aiming for recovery predict that, if successful, healthy systems still will not be viable until at least 2032. Demand is high because of artisanal pressures and high prices With timely laws and community efforts, recovery remains optimistic. Harvests reached heights of almost 60,000 tons to keep up with demand. "Barton Seaver: Sustainable Seafood" Fish make up a large percentage of the animal protein consumed worldwide, meaning that... The benefit of over 500 million people Sustainability provides security! "Pavan Sukhdev: Put a value on nature!" Fisheries offer employment for 180 million people around the globe. And peace of mind. The problems are complex, but the solutions are simple. Foremost, governments must decrease overfishing and by-catch through strict policies. But to do so... "Working to harvest fish stocks at a non-destructive rate" There needs to be a greater understanding of species life histories, migration patterns, etc. Support sustainable fishermen and seafood companies. Be aware of species that may be in danger. Eat alternatives! Restaurants drive demand, so request ocean-friendly seafood to make change happen. Support causes that benefit small-scale practices while limiting industrial fleets Think organizations such as Greenpeace Check the M.B. Aquarium Seafood Watch Program And... Always remember to fish responsibly Have fun. Follow the rules. Protect the future.
