Figure 1. Harvest and escapement of southeastern
Alaska pink salmon between 1962 and 1997. Escapement
estimates are based on peak counts of index streams and, therefore, represent an index to
total escapement.

southeastern Alaska during January, 1949 to 1997.
The dashed line is a lowess curve (f = 0.35).
