Aquaculture and Future of Seafood

The demand for seafood has never been greater. Evidence is everywhere — from an explosion of sushi bars, to all-you-can-eat shrimp bonanzas at restaurants across the U.S. To meet that demand, the fishing industry has gone high tech and in high gear, but it's emptying the oceans far faster than fish species can recover.

Research shows that roughly ninety percent of large predatory fish have been depleted from the world's oceans and in some areas whole fisheries have collapsed.

Fish farming or aquaculture is being billed as a solution to the over-fishing crisis. But there is great debate among the scientific community over the practice, with many arguing that present methods have a negative impact on wild ecosystems and the health of the fish that is produced.

Hear a discussion on the the promises and perils of fish farming.
