skydriftin,

That is an interesting question to which I have no answer.
Perhaps smalma or another more informed member might be able to help.

For the Snohomish System:
1996 plants = 414,000
'97-98' harvest:
total tribal = 58
recreational = 2067
plants/harvest = 194.82
Percent of plants harvested = 0.513%
Hatchery Escapement = 536

1997 plants = 196,200
'98-99' harvest:
total tribal = 377
recreational = 4416
plants/harvest = 40.94
Percent of plants harvested = 2.44%
Hatchery Escapement = 816


For the Skagit System:
1996 plants = 289,000
'97-98' harvest:
total tribal = 67
recreational = 347
plants/harvest = 698.07
Percent of plants harvested = 0.143%
Hatchery Escapement = 449

1997 plants = 328,400
'98-99' harvest:
total tribal = 185
recreational = 1055
plants/harvest = 264.84
Percent of plants harvested = 0.378%
Hatchery Escapement = 364

It seems clear that 41 to 195 smolts planted per fish harvested on
the Snohomish System is a whole lot better than the Skagit System
where the rate was 265 to 698 smolts planted per fish harvested.

I counted the total tribal as hatchery although some might be wild.
The two years were the only years where complete data was available online.
