Invasion of 'bloody red shrimp' hits Erie

The invasions continue.

Now, Great Lakes waters show signs of a Hemimysis crisis.
Hemimysis anomala, commonly known as "bloody red shrimp," first appeared in Muskegon waters connected to Lake Michigan in November 2006. Live samples of these tiny, shrimp-like crustaceans also appeared in samplings taken off Oswego in Lake Ontario.
Fish stomachs sampled at Port Dover, Ont., on the north shore of Lake Erie, indicate this creature may inhabit Erie waters.

Hemimysis anomalia differ from mysis relecta, a mysis-family member that inhabits deeper Great Lakes waters. Invading bloody red shrimp forage in warmer shallow waters, competing for food with other invertebrates and smaller fish.
Its affect on fisheries is uncertain. A National Center for Research on Aquatic Invasive Species (NCRAIS) report noted, "In some lakes mysid introductions have preceded the growth of salmonids, whereas in other lakes they are associated with rapid declines in abundance and productivity of pelagic (suspended, off-bottom) fish."
The NCRAIS unit at Ann Arbor, Mich., seeks samples found anywhere in Great Lakes waters. For collecting and mailing instructions, go to: and click on "Aquatic Invasive Species" and then "(hemimysis anomalia) recently discovered."

>Fish: healthy food

Health scares spawn uncertainties about eating fish. But a Harvard research study, published in the Oct. 2006 Journal of the American Medical Association, concludes eating fish "outweighs the risks from trace amounts of mercury."

Omega-3 fatty acids in fish have been found to "restructure brain matter tied to positive mood and emotions," according to an American Psychosomatic Study. Those happy findings can be viewed at:
