FIGURE 10. — Monthly length-frequency distributions of weakfish, Cynoscion regalis, from York 

 River, 1972-74. Mode I, young-of-the-year; mode II, yearlings. Frequencies expressed as log (.r + 

 1) at 5-mm increments. Only the lower portion of river (strata A-D) is represented in 1974. 



FIGURE 11.— Length-frequency dis- 

 tributions of weakfish, Cynoscion re- 

 galis, by river distance (strata) up- 

 stream of the York River estuary. 

 Pooled total, August to October 1972- 

 74. Strata: A-G in York River, M = 

 Mattaponi River, P = Pamunkey River. 

 Frequencies expressed as log (x + 1) at
