Segment One Fish in the News. Each week the Bailey Brothers start the Pet Fish Talk Show with some fun and interesting stories about fish in the news.       Electric Ray newly discovered and named Electrolux addisoni after the Electrolux vacuum cleaner.     In South Africa New fish named after vacuum cleaner. South African scientists have discovered a new genus and species of an attractively patterned electric ray off the east coast of South Africa and they have named it after a vacuum cleaner company. The new electric ray, named Electrolux addisoni, is described in the latest issue of the journal Smithiana Bulletin by Leonard Compagno and Phillip Heemstra. Click here to read more.   A Canadian Scientist has found that Pollution risks to people slip through nets in tests on fish. Professor Frank Gobas, at the Simon Fraser University in British Columbia, has identified a new class of chemicals which fish seem to be able to get rid of but which could accumulate and cause problems in people. "These ... chemicals, representing a third of organic chemicals in commercial use, constitute an unidentified class of potentially bio-accumulative substances that require regulatory assessment to prevent possible ecosystem and human-health consequences," Click here to read more.   On the Samoan Islands of Savaii and Upolu Butterflies quickly evolve and avoid extinction. When faced with extinction, butterflies on two South Pacific islands quickly developed genetic defenses that helped them fight back, a team of international researchers said on Tuesday. They said the butterflies' tale is the fastest example of natural selection observed to date and shows evolution can happen quickly when the stakes are high. In 2001, male Hypolimnas bolina butterflies on the Samoan islands of Savaii and Upolu were extremely rare. Just 1 percent of these butterflies - known commonly as Blue Moon or Great Eggfly - were male. They were under attack by the Wolbachia bacteria, a parasite passed down through the female that kills off male butterflies before they can hatch. Click here to read more.   How to save the world's oceans from overfishing Explains the Monterey Bay Aquarium's Mike Sutton. Global fishing stocks are in trouble. After expanding from 18 millions tons in 1950 to around 94 million tons in 2000, annual world fish catch has leveled off and may even be declining. Scientists estimate that the number of large predatory fish in the oceans has fallen by 90 percent since the 1950s, while about one-quarter of the world's fisheries are overexploited, depleted, or recovering from depletion. Click here to read more.   The Promise of the Blue Revolution Aquaculture can maintain living standards. Environmental sus­tain­ability is already very difficult to achieve with today’s 6.6 billion people and average econo­mic output of $8,000 per person. By 2050 the earth could be home to more than nine billion people with an average output of $20,000 or more. Many environmentalists take it for granted that richer countries will have to cut their consumption sharply to stave off ecological disaster. There is another approach. Global public policies and market institutions can promote new technologies that raise living standards yet reduce human impact on the environment. A crucial group of such technologies is aquaculture, the farming of marine animals, which can support growing human consumption of fish and other aquatic species while relieving intense pressures on ocean ecosystems.  Click here to read more.   In Washington, D.C., Official says veterinarians could aid human health. The nation's top public health official on Saturday urged veterinarians to work more closely with human-health researchers to curb contagious diseases. "Thirteen out of the last 14 new infectious diseases that have affected people have arisen from animals," said Dr. Julie Gerberding, director of the Atlanta-based federal Centers for Disease Control and Prevention. "We need a health system that can do fast science, fast detection ... fast and effective communication, and a very, very important piece of this fast system is the alert veterinarian," she told the American Veterinary Medical Association's annual convention here. Because animals share our food and water supply and have greater contact with the elements, their sicknesses can provide an early alert to environmental problems, human disease - and even bioterrorist attacks. Click here to read more.   Segment Two   Segment Three   Segment Four   A Big Sincere Thank-you for calling during the show to Evan from Colorado and Chris from Australia.
