This is a not a new idea however I feel your pain. Remote site incubators have been around for a long time and are still continuing to be used. The idea is to use "native/wild" broodstock eggs in a controlled flow incubator, which then releases the fry into the home river system. These fry would be considered wild and this method would significantly eliminate the natural mortality due to silt, flooding, predation etc. on the egg to fry production. Should be slam dunk however nothing is ever that easy as they have been trying methods along this line for about 100 years. Kick started fry plants on river systems with no "carrying capicaty" for your programs fry/juvenials won't work unless your have the habitat to rear then. Make the rearing/spawning habitat and the fish will come without the use of encubation enhancing devices. If you are trying to save the last genetic fish in the system (Idaho sockeye) then artifical methods should be used otherwise I think we should be making the effort to solve the other problems that are limiting the systems' production, i.e. 4-H's
