No, drain and seine to get all the high dollar fish out, then nuke to remove all the small ones. Then start over with single sex fish that you are 110% sure of....

I'm thinking that introducing a predator in there will take away growing inches from the high dollar fish, either to reduced available biomass space or stress introduced by the predator fish.
