How are SAFE areas even called selective fishing..... Why push it to that?

Examples 2009:
The combined Youngs Bay winter/spring/summer fishery stock composition is based on VSI and CWT analysis with a total of 1,098 Chinook (35% of the combined catch of 3,123 Chinook) examined for fin marks and CWTs and 86 CWTs collected. The 2009 combined winter/spring/summer catch was comprised of 63.5% spring Chinook and 23.0% SAB fall Chinook destined for Select Area sites, 2.8% upriver spring Chinook, 0.7% upper Columbia summer Chinook (after June 15), 4.9% Willamette River spring Chinook, and 5.2% spring Chinook destined for the Cowlitz, Kalama, Lewis, or Sandy rivers. Based on scale readings, which were verified with CWTs, the age composition of the catch was <1% Age-2 (all SAB jacks), 13% Age-3, 70% Age-4, 16% Age-5, and <1% Age-6 fish.

Example Deep River 2009:
The Deep River winter/spring fishery stock composition was based on VSI and CWT analysis with a total of 122 Chinook (100% of the catch) examined for fin marks and CWTs, and 12 CWTs being collected. The 2009 Deep River catch was comprised of 59.0% spring Chinook destined for Select Area sites, 13.1% upriver spring Chinook, 17.2% Willamette River spring Chinook, and 10.7% spring Chinook destined for the Cowlitz, Kalama, or Lewis rivers. Based on scale readings, verified with CWTs, the age composition of the catch was <1% Age-3, 37% Age-4, and 62% Age-5.

I still don't understand going in that direction??
