Invasive spiny water flea comes with a big cost
European water flea is wiping out important invertebrates in North American waters
A new study by Dr. Jake Walsh, a researcher in the Center for Limnology at the University of Wisconsin, found that the spiny water flea has a huge appetite for the native Daphnia zooplankton. Daphnia were previously able to keep the lake clean and clear by consuming algae, until the arrival of the spiny water flea, which devoured the Daphnia.
Through various models and estimates, the study was also able to assign a dollar value for clear water to the residents of the lake area ($140 million), as well as a cost for a clean up ($80 to $160 million). The study demonstrated that apart form the ecological cost, there is also a monetary price that comes with invasive species.
