Port Distribution of Hemimysis Anomala - One of the Newest Great Lakes Invaders

In 2  6, the bloody red shrimp, the mysid Hemimysis anomola was   discovered in Muskegon MI, and has since expanded to northern Lake   Erie and Lake Ontario. The mysid is an omnivore, and has potential   to further disrupt the lower food web of the Great Lakes. The   distribution of Hemimysis is not well known, but is thought to  occur along ports where ships offload cargo and ballast.    The objectives of this research are to document the spread of   Hemimysis in central and southern Lake Michigan, Saginaw Bay Lake   Huron, and the Huron-Erie corridor. In all ports where Hemimysis is   found, estimates will be made of Hemimysis age structure, size, and   reproductive state.    In Fall 2  7, CILER and NOAA scientists sampled several sites in the   Huron-Erie corridor from Port Huron through the Detroit River and   into western Lake Erie. Bottle traps and plankton net tows were   deployed at the sites, and samples were analyzed in the laboratory.   No Hemimysis specimens were found at any of the sites.    (AIS); (aquatic invasive species); (ANS); (aquatic nuisance   species); (bloody red shrimp); (Hemimysis anomola); (bloody-red   mysid); (bloody red mysid); (bloody-red shrimp); (Lake Michigan);   (Saginaw Bay); (Lake Huron); (Lake Erie); (Detroit River)
