I loved this method for cooking fillets of fish https://food52.com/recipes...
Could it work on a whole fish (pike perch)?

I don't see why it can't. It might take a little longer with a whole fish.

It should work fine. Be sure to use a thermometer to ensure you don't overcook the fish. (which is just as bad as undercooking it, imho).
Skip the trip to the vending machine.
