Figure 4 



Spawning-date distributions for juvenile herring (Clupea pallasi) caught in (A) 1999 

 and (B) 2000. Vertical bars represent dates and magnitude of observed spawning (eggs 

 deposited), heavy lines represent the spawning-date distribution of juveniles without 

 the mortality correction, and light lines represent the spawning-date distribution 

 corrected for juvenile mortality at an instantaneous rate of 0.016/d. Distributions are 

 smoothed with a cubic spline interpolation. Data on observed spawning were provided 

 by D. Watters, CDFG (see Footnote 2 in the text).
