Fishery-dependent Shad Sampling

The season for commercial shad fishing is open from January 15th to April 30th (depending on river system).

SCDNR is required by the Atlantic States Marine Fisheries Commission (ASMFC) to conduct fishery-dependent sampling for American shad. Field crews sample commercial fishermen’s catch (200 fish) throughout the open season.


Measurements, weights, and sex are recorded. Also, scale samples are taken from each fish. This information is used to generate age frequencies, sex ratios, and monitor the overall catch trends.
