Maybe somebody can set me straight here...
I have a PDF that I downloaded years ago. There was a legitimate scientific paper attached to it, but I cannot seem to find it.

Use this document as a grain of salt guideline.
I have always been perplexed on the concept of 'minimum size limits' for walleye and pike. A 3lb walleye and a 4lb pike will be around 10 years old.
Any pike bigger than 63cm will likely be part of the active breeding population (i.e. 5 years or older). Likewise, any walleye larger than 40cm will likely be part of the breeding population.
Slot sizes make the most sense to me, but they are more difficult to enforce. Saskatchewan's policy of 'maximum retention of which only 1 may be larger than XXcm' is great, but SK has provincially a more sustainable fishery because the sheer amount of fish holding water, but they still have fairly restrictive retention with greater human population access.
What do you think of minimum size limits?
