Woody, the highlighted statement honestly does not take into account human nature and greed. I don't think it is so much a question of "farming" them, but very little in traditional trapping regimes incentivizes trappers to completely eradicate pests. It is a short-sighted business model...
If near eradication and long term monitoring was part of the model, it might be a different proposition. The traditional regime also fails to address the issues around trapping remote and inhospitable areas, or those with harder access.
