Awhile back, I was reading the bio of the guy that founded Scotty Plastics. He is old and rich now, and is trying to direct his remaining energies in benevolent directions. He invented a plastic tray for holding salmon eggs in the river bed. Sort of a man-made redd. His experiments showed a MUCH higher survival rate using the trays than natural redds. If wild fish eggs were put in these trays, wouldn't the result be wild fish? The only negative aspect I can think of would be the litter from old plastic trays in the river and that's easy enough to fix.

I am nowhere near an expert of this subject and DO NOT want to start another "hatchery vs wild" argument. But I would appreciate if some of the members of this board who know more than me could explain if this is a viable idea.
