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.       Troubled waters ... the aggressive Garfish is an unwelcome visitor to the city of Shanghai in China.     Chinese Sturgeon fish is struggling to survive in the Yangtze River in China.     Eating Eel ... could improve the quality of life for many New Zealanders by helping to stop rise in diabetes.     In Shanghai, China, Finding Predatory Gar Fish Worries Local Authorities. Local fishing supervisors announced yesterday they found a garfish, an exotic species that is as aggressive as a piranha, for the first time in the city in an illegal fishing net during a recent inspection. Officials said the fish could seriously harm aquatic creatures if it is allowed to breed in open water, and noted it is poisonous to eat. They advise fishermen to report to the local fishery department if they find the fish or other strange species.

The future of the Chinese Sturgeon, a large migrating fish that has survived in the Yangtze River for nearly 140 million years, is increasingly threatened by pollution, damming, overfishing, and heavy boat traffic in the waterway, according to a new report co-authored by the Yangtze River Water Resources Commission, WWF, and the Nanjing Institute of Geography and Limnology. Human activities have caused a general degradation in aquatic ecosystems throughout the river basin, the report says.

A traditional Maori staple - eel - may hold the answer to stemming the growing tide of obesity-related type-2 diabetes. The prevalence of obesity-linked diabetes has rocketed ahead of predictions, leading to dire forecasts about its expected toll on health services and the quality of life of a substantial proportion of people. But health researcher Marie Benton believes a simple intervention incorporating the omega-3 fatty acid found in high quantities in eel could prevent many from developing the disease.

Robotic and un-crewed submarines could operate more effectively by mimicking the way some fish probe their surroundings with electric fields, a new study by Malcolm MacIver and colleagues at Northwestern University in Chicago, US, has revealed.

For the past three years, a noxious weed has grown practically unchecked on that arm of the Tar River Reservoir. But the city of Rocky Mount began a large scale treatment plan for Hydrilla, a weed that grows like a sort of water kudzu and has infested about 270 acres. "For the most part, (the water) should be pretty open (this year)," said Mark Heilman, aquatics technology leader at SePRO, the Whitakers-based company treating the Hydrilla. "We're trying to be aggressive." Hydrilla grows vertically to the water surface, then horizontally across it at rates of up to an inch per day. Last year, the city used a copper-based herbicide that couldn't be applied as fast as the Hydrilla grew. The swampy mess prevents boaters from using the water.

Biologists fighting aggressive alien seaweeds that destroy Hawaiian reefs are turning to sea urchins and fish that graze on the plants in hopes that their feeding will help control the invaders. "If people can raise herbivore (plant-eating) stocks quite substantially, I believe it will have a big impact," said coral reef ecologist Ivor Williams, of the Hawai'i Coral Reef Initiative and the state Division of Aquatic Resources. Researchers put collector urchins on weed-infested reefs in cages in Kane'ohe Bay, and found that they quickly ate away much of the alien limu inside their cages.

As fisherman flock to Jefferson Park in Menasha, they're seeing more than boats floating by. To me it seems different because it's early. Normally when you get the dog days of summer you see fish dying. But this is too early," said Steve Sokol, fisherman. Local fisherman say sights like this have become common around Menasha shores with dead fish floating in. The DNR say they believe this could be a direct result of the virus. They say symptoms to look for inside of the dead fish to see if they actually have the virus include bugging of the eyes and redness around the body.

Researchers have identified a group of bacteria that can detoxify a common type of polychlorinated biphenyls, PCBs. These carcinogenic compounds, once used as coolants and lubricants, have contaminated more than 250 U.S. sites, including lake and river sediments. The discovery is a first step toward a bioremediation strategy that would naturally detoxify the PCBs without risky removal of the sediments in which they persist. Development of bioremediation technologies for PCB cleanup would offer an alternative to sediment dredging and disposal in landfills, which is the most commonly used method for removing PCBs used today. Dredging is controversial because of the invasive nature of this technology and the risk of spreading contaminants.
