Curt raises an interesting point about the Snoho. The wild coho there are doing well enough to support fisheries. While there may be questions about how the productivity could be naturally enhanced the fact remains that the run is not only self-sustaining but does support harvest.

Yet, this is "not enough". We (the Royal We) want more than nature can produce. As population grows and demand for fish increases it seems inevitable that We are willing to trade natural production for hatchery enhancement.
