Apparently there is at least 10 years worth of data available to provide comparative exploitation rates.

If (an important qualifier) the number of returning adults is a limiting factor in ability to increase brood stock production how would not clipping those fish impact returns?

Reading the numbers the SUS sport fishery has an impact of 9.4% on clipped fish but 4.2% on unclipped fish. Just playing with those numbers and with all other factors the same it appears as though NOT clipping them would reduce impact by 5.2% so how many additional adult returns would that produce in river?

You can also throw in another 1% potential savings tied to the SUS commercial troll fishery and roughly 4% in the Canadian fishery and .6% AK.

Total potential close to 11%.

Do I have those numbers right and, if so, how many additional returning fish would that represent?
