spiny waterflea

A lot about the ecology of spiny waterflea is not yet well understood; however, concern is high that this invasive species may cause major problems to lake ecosystems. At MAISRC, research focuses on slowing spread, indentifying long-term impacts, and evaluation the food web effects of these microscopic zooplankton.

Ongoing research

  • Evaluating fishing gear to determine what is most high-risk for accumulating spiny waterflea. Results are showing that gear that is pulled through the water is riskier than stationary equipment such as anchor lines. This will help guide lake users in prioritizing what gear to pay most attention to when cleaning

  • Quantifying the impacts of spiny waterflea on walleye growth rates and food webs. Initial findings show that walleye in their first year grow more slowly in lakes invaded by zebra mussels and spiny waterflea than in uninvaded lakes

  • Analyzing lake sediments to identify the types, magnitude, and timing of changes that occur to lakes after spiny waterflea invade
