Using a fishwheel to capture sea lampreys

Capturing upstream migrating sea lampreys is an important practice   for the sea lamprey control program. In this study, the use of a   fishwheel to capture sea lampreys was tested in the Cheboygan River   and sea lamprey behavior around the fishwheel was video recorded.   During the study, the fishwheel captured over 1,    sea lampreys and   had very few instances of by-catch. In addition, when compared to   the conventional traps also fished in the Cheboygan River, the   fishwheel proved to be as easy or easier to operate and maintain.   Video observations determined that many sea lampreys encountering   the fishwheel were not captured and some that were captured escaped   before being lifted from the water. Despite these observations,   simple modifications to fishwheel design and placement will likely   increase the capture rate. More research is needed to investigate   the use of fishwheels in conjunction with conventional traps and in   tributaries not suitable for current trapping operations. Overall   results indicate that fishwheels could be a viable way to capture   additional sea lampreys for the sea lamprey control program.     (sea lamprey); (sea lampreys); (Michigan); (Lake Huron); (AIS);   (aquatic invasive species); (ANS); (aquatic nuisance species);   (Petromyzon marinus); (Cheboygan River)
