Some information from a formal review process led by Fish and Wildlife’s Endangered and Nongame Species Program that was conducted in 2014 and 2015 to determine the status of our native freshwater fishes. The procedure is known as the Delphi Technique.
It is a systematic method for reaching consensus among experts in which absolute, quantitative answers are either unknown or unattainable. It is an iterative process characterized by anonymity among the participating experts, controlled feedback via the principal investigator, and a statistical estimator of group opinion. By structuring the group communication process, the Delphi Technique helps the group reach a consensus of opinion by incorporating all available data and disseminating those data among all participants.
NJFW created species distribution maps using GIS, based on data collected from 2000 through 2012. In addition to data collected by the Bureau of Freshwater Fisheries Research and Management Unit, data were supplied by the Department’s Bureau of Freshwater and Biological Monitoring, the Pinelands Commission, and United States Geological Survey. Results informed the update of the New Jersey’s State Wildlife Action Plan.
The following recommendations were made by the Committee:
- Endangered (Candidate): Bridle Shiner, Ironcolor Shiner
- Threatened (Candidate): Slimy Sculpin
- Special Concern (Candidate): American Brook Lamprey, Comely Shiner, Northern Hog Sucker, Blackbanded Sunfish, Mud Sunfish, Shield Darter, Brook Trout
