This lesson will explore the phenomenon of whitefish population decline in the Jordan River by Green Bay, Wisconsin. Whitefish are an important source of food and commerce in the Great Lakes, but for over a century the population has been in flux due to a number of factors ranging from human impact to invasive species and climate change. As students learn about aquaculture efforts to address the fluctuations in fish populations, they will model the impact of invasive species on the food web, engage in water quality testing, and simulate species competition.
- Know what aquaculture is and how it works
- Understand how invasive species affect the food web dynamics and can impact whitefish populations
- Be able to test water samples for various markers of water quality and ecosystem health
