I was reading that a fish that has become piscavorius by their first
year they will be larger and stay larger than other fish in the same
year class. I also know that brook trout have voracious appetites.
Sounds like it's healthy enough that a slot limit would be perfect.
Your argument that the harvesting of "large fish" is good for the
fishery has been disputed. There are a number of new studies that have
shown that harvesting the larger fish leads to a population of small and
more timid fish. With a quick Google I wasn't able to find the studies
themselves but here's a discussion of two of them.
