Keep a perspective that is holistic, risk-adverse and adaptive.
Maintain an “old growth” structure in fish populations, since big, old and fat female fish have been shown to be the best spawners, but are also susceptible to overfishing.
Characterize and maintain the natural spatial structure of fish stocks, so that management boundaries match natural boundaries in the sea.
Monitor and maintain seafloor habitats to make sure fish have food and shelter.
Maintain resilient ecosystems that are able to withstand occasional shocks.
Identify and maintain critical food-web connections, including predators and forage species.
Adapt to ecosystem changes through time, both short-term and on longer cycles of decades or centuries, including global climate change.
Account for evolutionary changes caused by fishing, which tends to remove large, older fish.
Include the actions of humans and their social and economic systems in all ecological equations.” "

Again...you are not looking at the big picture...just trying to cloud the common sense facts.
On one hand you are advocating killing the trout when they are small as this is a put and take lake...therefore very little chance they will spawn period.
The proposed change to provide a readily accessible quality fishery near Calgary will allow the delayed harvest of Cutties after 20 inches. Prior to reaching 20 inches they will have a chance to spawn at least and maybe for a couple of seasons before harvesting is possible. Harvesting before at 12 inches...no chance at all to spawn.
Now factor in that this is a stocked put and take lake...not being proposed now or in the past as a lake regulated for harvest based upon natural reproduction and replacement fisheries management.
So what are you saying... Now you want to slash harvest dramatically in order to allow successful natural spawning and population replacement/recruitment? You want to allow harvest of only cutties less than 12 inches and if they grow bigger then they will be released to spawn?
Your arguments are so all over the map...you make reasonable debate sometimes taxing...but always interesting.
Good try on this one...but IMHO you have failed to make a valid point.
P.S.
I am getting seriously concerned you are against put and take fisheries based upon leading arguments like this.
