Zooplankton Study at L.C.R.I.

The Long Term monitoring project of Lake Champlain is one of the biggest projects we are conducting at The Lake Champlain Research institute. The project is funded and regulated by Department of Environmental conservation of New York and Vermont. Under the Long Term Monitoring program there are many sub monitoring programs are carried out. One of the main sub Monitoring programs we do is the study of Long term Zooplankton trends in the Lake Champlain and how they affect the fisheries in Lake Champlain. Our main focus here at LCRI is Class Crustacea of Phylum Arthropoda and Class Monogononta of Phylum Rotifera. By definition, Zooplankton are heterotrophic plankton organisms drifting in oceans, seas, and bodies of fresh water. In Lake Champlain, Zooplankton are the primary food source for the pelagic food web, supporting the lake’s Atlantic salmon and lake trout fisheries. Time to time rapid decline of zooplankton populations and their bio-volumes were observed due to invasive species like Zebra mussels and Alewife in the past two decades. Zooplankton is the engine that drives the fishery, without the energy they provide there would be no fishery in Lake Champlain.

I am a Biology graduate from SUNY Plattsburgh, NY. I was employed at Lake Champlain Research Institute, Plattsburgh, NY during 2011-2013. There, I studied, longterm trends of zooplankton in Lake Champlain. One day, I hope to utilize my skills and experience towards a conservation of aquatic biology and make a worthy contribution to the science.
