Fishery-independent Shad Sampling
SCDNR is required by the Atlantic States Marine Fisheries Commission (ASMFC) to conduct fishery-independent sampling for American and Hickory shad.

Field crews sample various river systems with drift gill nets during shad season. When shad are caught, they are measured, weighed, sexed, and tagged. Some of these fish are then recaptured by commercial fishers later in the season. This information is used to generate estimates for fishing mortality, length frequency trends, and age data.
