This probably isn't a novel idea and may have been discussed on here before but is there any reason why Chinook/King salmon would not be a stocking option for Cayuga or Seneca Lakes?
I know that natural spawning areas would be limited but the depth and size of the lakes seem plenty big enough. There seems to be ample forage as well. I guess that could be a worry though if they would quickly deplete it.
I can only imagine how cool it would be catching big salmon on the Fingerlakes. They would also likely taste better and be healthier to eat then from Lake Ontario.
