Here's a table on water use restrictions from Keystone Hatcheries (a Pond Boss vendor), according to this table there is no restriction on eating fish when using Reward/Cutrine mix. Which corresponds to everything else I've read about Reward/Cutrine. I don't have any knowledge or experience with any other chemical.
Keystone Hatcheries web page You should be able to safely eat your fish. Well as long as you don't poke your eye out with your fork while playing "airplane."
