Counting and Improving Fish Populations

For the first time, scientists conduct a census of ocean life in the Gulf of Maine. They've already found 50 percent more species than were estimated to live there. Plus, a new study shows that marine reserves — where fishing is restricted — result in healthier coral reefs and sustained fisheries.
