Welcome to Pond Boss!!!
You've got an interesting project going there. How many Yellow Perch, using an average weight, would you expect to harvest to yield 100-150 lbs/year of Yellow Perch fillets?
I'm just guessing here, but I would think a healthy 14" long YP would produce less than 1/2 pound of meat, probably less.
If you start with (400) original stocker Yellow Perch, it sounds like you might be harvesting several hundred YP each year, after year 2 or 3. Reproduction of YP could occur in Year 2 or 3 depending on size of the YP stockers.
It's almost like you might not want a predator fish in order to produce enough YP for harvest, yet you'd need enough forage to grow the YP to harvest size.
