That's a good question.
When we asked why there was no enforcement on the mid-Fraser, this was the response we got from DFO:
In order to preserve operational integrity and to maintain strategic flexibility, DFO’s Conservation and Protection (C&P) Branch does not provide specific statistics on numbers and frequency of enforcement patrols.... The C&P enforcement program uses a wide range of tools to protect Canada’s fisheries resources. Using a risk-based, intelligence-led approach, C&P deploys fishery officers throughout the province to respond to priority issues using a variety of methods....
Maybe you got a response, but that was the response we got when we inquired why there were no fisheries officers on the mid-Fraser this summer and why sockeye poaching on the mid-Fraser was rampant. They didn't even acknowledge there was a shortage of fisheries officers.
