Bass were released into burbaby lake by fisheries on that 1920
Not according BC fisheries inventory database.

If people wish to retain bass where they are legally allowed to, then they are welcome to do so. Suggesting that they shouldn't is pretty silly, just as telling people that they are driving too fast when they are going within the speed limit. Killing as many as you can might temporarily disrupt the population, but it will not make a difference in the long run. You're simply opening up new niches for other existing bass to occupy and succeed. A systematic cull is needed if one wishes to see the elimination of an invasive species in a particular ecosystem, but it is costly and only justified if the invasive species poses a threat to native species that are endangered.
Personally, I prefer to eat a bass than a trout. They are absolutely delicious when pan fried or steamed.
