I have to agree with the some of the others that removing the desired fish for harvest at fish ladders/traps is a very efficient way harvest fish while being extremely selective on what is harvested with minimal impacts on the wild fish to be released.

The question quickly becomes why not limit all harvest (including the recreational fishing) to those locations as well. Those that want a fish can campout at the "fishing site" and stand in line to recieve their fish as they are captured. Not ony would the harvest be done selectively it would be easy to assure the equilable distribution of the "harvest" to all the "users".

With complete selectively harvest, minimal impacts on the listed wild fish, and equitably distribution of the catch what is the down side of that sort of approach?
