Sockeye peaked in late
1960s

(Target 50,500)

Lower Principe (brown) has remained fairly productive while others collapsed

Escapement from 1950 to 1997

Trends

In Area 5

Escapement

A problem??

If so, DFO doesn’t recognize one

Another pattern: Diversity of runs lost in 1960s
Then the “outer Banks Island strengthens
then they all collapse; especially Lower Grenville

Target

25,000

Coho are similar to Chum: loss diversity;
Outer Banks remains strong then all collapse Target: ???

Pinks look to have done best,

but even they seem to have lost diversity
