The NJ Department of Environmental Protection consists of many different programs / units.
The Division of Fish & Wildlife is one,…..it manages the State’s fish & wildlife populations.
Another is, Water Monitoring and Standards. I’m sure that their Bureau of Freshwater and Biological Monitoring
http://www.state.nj.us/dep/wms/bfbm/ are the ones that attended that conference.
They use biological indicators (fish, invertebrates…), as well as water chemistry, to monitor & assess the quality of the State’s freshwaters.
NJDF&W and WMS share data, and work together on projects.
