Ualburg and Sykes (1957). The study Indicated that in 1952 the commercial catch o£ shad In the James River was 993,963 pounds, the fishing rate 73 

 percent, and the size of run 1,363,149 pounds. 



Walburg and Sykes (1957), The authors concluded that there was a significant difference in Che tag-recovery-catch ratio, therefore, the tag return data 

 could not be used to estimate the weight of the shad population and escapement. 



Nichols and Massmann (1963). The findings showed an estimated catch of 463,000 pounds of shad, a fishing rate of 55.2 percent, and a total population of 

 839,000 pounds in 1959. The fishing rate and population size for each year 1953 through 1958 were calculated.

Nichols (1960). The findings suggested that shad having spawned once In the York River would return to spawn again in the same river system. 



Massmann and Pacheco (1961). This paper shows that most fish recaptured in Call and winter were taken in the same river system In which they were tagged, 

 while some of those recaptured in spring and summer moved considerable distances. The distribution of tag returns suggested that subpopulations of striped 

 bass were present in the York, Rappahannock, and James Rivers.

Unpublished; Preliminary results indicated that the population size was 259,200 shad, the comnercial catch 69,250 fish, and the fishing rate 27 percent. 

 The spawning escapement was 109,410 shad to the North East Cape Fear River, 4,560 to the Black River, and 75,980 to the Cape Fear River above the Junction 

 of the Black. No conclusions could be made about the efficiency of locks for fish possage because of the small number of tagged fish recovered. 



Cooperative studies with William W. Hassler of North Carolina State University at Raleigh. 



Davis (1959). This paper concluded that the streamer type tag was the most satisfactory of the tags tested. 



Unpublished: Preliminary findings Indicated that about 1,544,200 and 1,488,600 pounds of striped bass were available to the commercial fisheries in 

 Albemarle Sound at the start of the 1956-57 and 1957-58 seasons, respectively. The fishing rate was about 35 percent. 



8 



Unpublished: A total of 1,632, or 31.1 percent, of the striped bass tagged and released were recaptured. The bulk of the recaptured fish remained Id 

 North Carolina waters. Seven tagged fish were recaptured outside North Carolina waters; 1 off the North Carolina coast, 5 in Chesapeake Bay and 

 tributaries, and 1 in Cape Cod Bay, Mass.
