Shad research includes both fishery-dependent (getting data from recreational and commercial fishermen) and fishery-independent (standardized scientific collections) sampling. Using this approach we monitor abundance, determine age distribution, collect genetic samples, and collect information on how angling success may vary with water level and flow rate. Our results will be used in a 5-year stock assessment conducted by the Atlantic States Marine Fisheries Commission.
