Determining Drivers of Fish Productivity
The Ecosystem Indicators of Fish Productivity project is designed to provide insights into what drives fish productivity in freshwater systems.
Past Research
Algal Blooms
The initial driver for the creation of the ELA was the need to understand the cause of excessive algal blooms (eutrophication) on the Canadian-U.S. Great Lakes, particularly Lake Erie.
Acid Rain
In the 1970s and 80s, fish populations in hundreds of thousands of lakes in eastern North America and northern Europe were deteriorating.
Aquaculture
Freshwater fish farms have the potential to help meet increasing demand for fish, but the effects of aquaculture are not well understood.
Reservoir Development
Studies at the ELA have looked at the impacts of hydro reservoir development on both greenhouse gas (GHG) emissions and mercury cycling.
Hormones
Waste from sewage treatment plants often contains chemicals known as “endocrine disruptors” such as artificial estrogen found in birth control pills.
Genetically Modified Fish
With a growing need for fish protein to feed the world’s human population, genetically modified (transgenic) fish are being proposed for use in fish farms.
Flame Retardants
Since the 1960s, flame retardants have been added to common products such as electronics, building materials and upholstery fabrics. These compounds are endocrine disruptors, neurotoxins and possible carcinogens.
