Study Uncovers a Predictable Sequence Toward Coral Reef Collapse
Using data from coral reef systems across the western Indian Ocean, researchers identified how overfishing creates a series of at least eight big changes on reefs that precipitate a final collapse. This information can help assessing the health of a reef and tell when to restrict fishing in order to avoid a collapse of the ecosystem and fishery.
Chile Reels in Salmon Farming
Chile is the second largest producer of salmon in the world. But these fish don’t occur there naturally. Instead, the salmon swim within enclosed nets, often tightly packed together. Kept off the country’s coastline, fish farms like these can pollute local ecosystems. But in Patagonia, Chile has begun taking steps to protect some of its wild waters from the farmed fish.
