Most algae are microscopic and serve as the main supply of "high energy" food for larger organisms like zooplankton, which in turn are eaten by small fish.
related to exposure to blue-green algae (e.g., stomach cramps, diarrhea, vomiting, headache, fever, muscle weakness, difficulty breathing), contact your doctor or the Poison Information Hotline (800-222-1222) right away.such as seizures, vomiting, or diarrhea after contact with surface water, contact your veterinarian right away.Report a Case with potential health effects caused by blue-green algae, visit the Department of Health Services.If you are (or your local community is) interested in collecting samples for analysis, please contact the Wisconsin State Laboratory of Hygiene at (800)442-4618.The Wisconsin Department of Natural Resources is not currently conducting any routine monitoring for blue-green algae or blue-green algal toxins.
Blue-green algae, also known as Cyanobacteria, are a group of photosynthetic bacteria that many people refer to as "pond scum." Blue-green algae are most often blue-green in color, but can also be blue, green, reddish-purple, or brown.Blue-green algae generally grow in lakes, ponds, and slow-moving streams when the water is warm and enriched with nutrients like phosphorus or nitrogen.When environmental conditions are just right, blue-green algae can grow very quickly in number.Most species are buoyant and will float to the surface, where they form scum layers or floating mats.When this happens, we call this a "blue-green algae bloom." In Wisconsin, blue-green algae blooms generally occur between mid-June and late September, although in rare instances, blooms have been observed in winter, even under the ice.Many different species of blue-green algae occur in Wisconsin waters, but the most commonly detected include sp.
