2 . A tagging and recovery program was 

 conducted during the fishing season, and it was 

 estimated that the overall fishing rate was ap- 

 proximately 20 percent and that the size of run 

 was 56,000 shad (fiducial limits 28,000 to 

 100,000). 



3 . Age readings of 292 scale samples 

 taken from the Edisto River commercial shad 

 catch revealed that the majority of males were 

 3 and 4 years old and most of the females were 

 5 years old. 



No spawning scars were found on any of 

 the scales examined, which indicates that 

 Edisto River shad die after their first spawning. 



4. Results of a spawning-ground survey 

 by L. E. Cable indicate that the major shad 

 spawning area in the Edisto River is between 

 West Bank and Givhans Ferry State Park. 



5. Because of the absence of previous 

 years' catch -and-effort data, the factors af- 

 fecting the abundance of Edisto River shad 

 could not be ascertained. It is urged that the 

 State of South Carolina establish a system of 

 collecting shad catch -and-effort records for 

 the Edisto River. When these data have been 

 collected for a period of years, a study similar 

 to that conducted in 1955 can be made to deter- 

 mine the factors that are affecting population. 

 If these factors can be controlled, proper man- 

 agement procedures can be initiated.
