...food chain - are being overfished for oil supplements. Bigger fish prey on menhaden, which eat omega-3-rich algae and in doing so clean the ocean waters off the Atlantic and Gulf coasts. By filtering up to 7 gal. (about 26 L) per min., menhaden help prevent oxygen-depleting algal blooms that lead to underwater dead zones. (See the top 10 green ideas...
...more efficient source of omega-3s is emerging, however, and it's made straight from the algae that give menhaden and other fish so many healthful fatty acids. Maryland biotech company Martek, which farms myriad algal strains in massive tanks, is marketing life'sDHA, an algal omega-3 supplement rich in DHA, which is especially beneficial to the brain...
...Algal blooms are a common and often menacing event along many U.S. coastlines. Some strains are toxic and can close beaches and poison seafood, posing a hazard to consumers. The National Oceanic and Atmospheric Administration (NOAA) maintains a forecasting system for the Gulf of Mexico to warn of harmful Florida blooms. On Thursday, on the other side of the continent, Senator Olympia Snowe, a Maine Republican, urged the NOAA to direct at least $500,000 to assess a disastrous red tide - a form of algal bloom. "The state of Maine is currently besieged by the most virulent red tide event...
While Alaskans may find the algal blob unusual if not frightening, scientists say they are nothing new in Arctic Ocean waters, though the blob itself might be a little weird. Brenda Konar, a marine biology professor at the University of Alaska Fairbanks, says algal outbreaks can and do occur even in icy Arctic waters. It just takes the right combination of nutrients, light and water temperature, she says. "Algae blooms," she says. "It's sort of like a swimming pool that hasn't been cleaned in a while." The blob, Konar says, is a microalgae made up of "billions...
...South Florida is having an ecological and hydrological meltdown, the legacy of a century of plumbing and dredging and growing without much thinking. The Everglades ecosystem now hosts 69 threatened or endangered species, and its rookeries and fisheries have crashed. Massive algal blooms are turning Florida Bay into pea soup. The region's reefs have lost up to 95% of their elkhorn coral; persistent red tides have made it tough for sunbathers to breathe at the beach...
