APPENDIX "A" 



Size Composition of Population Before and After Fishing 



Table 3 shows the length frequencies of clams in 500 square feet of 

 bottom in each area in autumn 19U9 and 1950 as determined from five- 

 square-foot bottom samples taken with a clamshell bucket. 



Frequencies for 19U9, which were based on 28 samples, have been 

 multiplied by 3 "5? to make them comparable with frequencies for 19^0 when 

 100 samples were taken o Frequencies in Table 3 smoothed by a moving 

 average of 3's are plotted as solid lines in Figures 8, 9, 10, 11, 12 and 

 13.
