This is an opportunity that won't ever come up again, Take the trophy and wish and hope it makes it through next year's spawn. It might make it through the transfer and survive. Maybe net off a large area where you can provide the right size and type of forage the fish wants. I think that would give the large lmb a good shot at surviving the transfer. Then after a time-release the fish by dropping the net and let it swim off into the sunset.
