Harvest
There are 3 types of salmon harvest:
recreational, tribal, and commercial. Up until the 1970's catch
rates often exceeded 90% of a total run. This means that 9 out
of every 10 fish in a given run were caught. To maintain sustainable
fish runs, most research shows that harvest should not exceed 20%
of a run. These unsustainable fishing practices devastated many salmon
populations. (7 of 15)
