Released today, UC Davis' annual Lake Tahoe health report describes a spreading Asian clam population that could put sharp shells and rotting algae on the spectacular mountain lake's popular beaches, possibly aid an invasion of quagga and zebra mussels, and even affect lake clarity and ecology."Our collaborative UC Davis and University of Nevada, Reno, science team found up to 3,000 Asian clams per square meter at locations between Zephyr Point and Elk Point in the southeastern portion of the...

U.S. senators from Michigan and other states are urging the Senate to consider tougher federal regulations on invasive species such as the zebra mussel. Sen.

Levin said the mollusks are believed to have entered the Great Lakes through ship ballast...

Invasive quagga mussels are replacing their equally destructive cousin, the zebra mussel, in calmer waters in the Great Lakes, Wisconsin researchers said. While zebra mussels still dominate in fast-moving streams and rivers, the larger quagga mussels prefer soft lake bottoms of sand and silt, said Suzanne Peyer, a doctoral candidate in the zoology department of the University of Wisconsin, Madison. Zebra mussels prefer to attach to hard surfaces, such as rocks, gravel, pipes and ship hulls,...

The zebra mussels that have wreaked ecological havoc on the Great Lakes are harder to find these days "” not because they are dying off, but because they are being replaced by a cousin, the quagga mussel. But zebra mussels still dominate in fast-moving streams and rivers. Research conducted by Suzanne Peyer, a doctoral candidate in the University of Wisconsin-Madison Department of Zoology, shows that physiological differences between the two species might determine which mollusk...

Unwanted zebra mussels have appeared in Utah's Electric Lake, to the surprise of many state wildlife officials who reported on the invasive mussels' presence on Wednesday. Officials expected the mussels to show up at Lake Powell first, rather than Electric Lake because it's a high-elevation lake with relatively few boaters. Boaters are often blamed for unknowingly carrying mussels into the lake from other bodies of water. The mussels "showed up in one of the least-expected places," said...

U.S. scientists say they've created an environmentally safe bacterial toxin to control invasive zebra and quagga mussels. The new bio-pesticide was derived from a common soil bacterium by researchers at the New York State Museum Field Research Laboratory in Cambridge, N.Y. Scientists in the U.S. Department of Energy-funded study said that when ingested in large quantities, the bacterium is lethal to zebra and quagga mussels but harmless to non-target organisms, including native freshwater...

By Ray Grass For the Deseret News Utah biologists' worst fears may come true. Early tests show quagga and zebra mussels may have found their way into three Utah reservoirs. Early tests, however, show that three of Utah's most popular waters -- Bear Lake, Flaming Gorge and Lake Powell -- have not been contaminated. Larry Dalton, aquatic invasive species coordinator for the Utah Division of Wildlife Resources, said samples were taken from 42 waters in Utah. He said Pelican Lake, Red Fleet...

By Anonymous OAKLAND -- Beginning next Thursday, water craft inspection fees will be imposed on boats launched at Lake Chabot Regional Park and two other lakes in Alameda and Contra Costa counties.

The fees, approved Tuesday by directors of the East Bay Regional Park District, will in part offset the cost of a pilot...
