New Sightings Elsewhere

From January, 1995 (update #23)

LEESBURG, Ind. - An angler retrieved a single zebra mussel July 30 from Lake Tippecanoe three miles east of here, according to Jed Pearson, a fisheries biologist with the Indiana Department of Natural Resources. Tippecanoe, the third Indiana lake to become infested with mussels, is located a few miles from Lake Wawasee and Syracuse Lake, a pair of connected lakes that have been infested since 1991. Many small lakes are located in this area of northeastern Indiana; all three infested lakes are located in Kosciusko County. Lake Tippecanoe is the headwater for the Tippecanoe River, a river that has the most diverse mollusc fauna in the Midwest, according to Indiana Department of Natural Resources Non-Game Specialist Bob Anderson. Anderson said the Tippecanoe River contains 48 species of native molluscs, including at least three that are considered endangered species by the federal government.

ANN ARBOR, Mich. - Michigan Sea Grant researcher Paul Marangelo reported finding eight new zebra mussel-infested lakes as part of the 1994 Michigan monitoring program; an additional five infestations were detected incidentally by lakefront property owners and a lake researcher studying native mollusks. Adult mussels were found in 11 of the newly identified lakes; veligers were found in the two remaining lakes. Most new populations detected during 1994 were located in the southern portion of the state. Four of the newly infested lakes were in Oakland County, four in the Lenawee-Jackson County area, and two in Washtenaw County. As of November 1994, zebra mussels had infested 25 Michigan inland lakes, 14 of which had confirmed adult zebra mussel populations. Twenty volunteers from 16 lake associations were trained this summer in a pilot project using volunteers to help collect samples for zebra mussel monitoring, according to Marangelo. Three infested lakes were used as controls to test the efficacy of the program. Marangelo said that samples collected by volunteers at the three lakes "effectively replicated and complemented professional sampling." Although no zebra mussel detections resulted from the volunteer sampling program of 12 additional lakes not previously sampled, the program produced the first known inland lake detection of the spiny water flea (Bythotrephes cederstroemi) in Long Lake, located in Michigan's Lower Peninsula.

The Zebra Mussel Update was a 4- to 8-page quarterly national newsletter published by the University of Wisconsin Sea Grant Institute from May 1990 through May 1997. The ZMU documented the spread of the zebra mussel -- an exotic nuisance mussel -- through North America's freshwater environments, especially the Great Lakes, and on efforts to control it.
