The problem with DFO is that it is run from the east by eaterners with an eastern mindset. Out there, DFO's job is to preserve a commercial fishing fleet. Entire towns economies depend on commercial fishing. Take that same mind set out here, where there are several industries that support a town (logging, mining, fishing, growing marijuana etc) and you end up with stupid decisions that make sense for commercial fishing, but not for preservation of a run of fish.
When was the last time there was a DFO minister from the west? Will there ever be one? I doubt it will ever happen. That position holds a lot of power over people's livelihoods in the east, so any ruling party will always give the ministry to an easterner.
