The idea of population control for the human species is just a simplistic, yet logical, hypothesis. Not to be taken seriously. Same with quick fix solutions of reducing limits or increasing fines. there aren't enough CO's around to effectively enforce current laws.
What is needed is proactive resource management. Something the average taxpayer does not want to pay for in Ontario. As long as we destroy spawning areas and habitat, pollute, develop wetland, dam rivers, drain down lakes for our consumption, the fishery suffers. Reduced limits are not going to make up for the damage being done. Increased hatchery outputs might help, but that, too, is just a bandaid approach.
Habitat protection and rehabilitation, and spawning ground protection, will achieve superior results. Ensuring that a company like EB Eddy can never again wipe out a fishery with another chemical spill. Stop the development of wetlands. Reduced speed limits in prime shallow water breeding areas. These are proactive ways to help the fishery, but they are expensive.
