I think there are certian salmon species that can sustain harvest and some that cant. Ones that can only can if they are healthy. Such species would be Sockey Chum and Pinks. In a perfect world there are too many of theese fish to actually spawn, just not enough reds. The reason why there should be so many of theese species is because they are the backbone of any river system. There dead bodies wich should cover the river banks and bottom are the food source for the three other species being Chinook Steelhead and Coho and dont forget resident trout and Sea Run Cutts.

If you look at the healthy rivers in Alaska, wich have huge numbers of the three stated above and also good numbers of the others but not nearly as many you see that our rivers are missing the backbone and the chance to grow. Without surplus theese backbone species our rivers just dont have the potential that they once had.

There just isnt a surpluss of wild Chinook Coho and steelhead, even in a perfect world. I dont think nature designed the last three for harvest.

Just my opinion.
