The easiest way I have found to cut them up is to freeze them solid then take them out of the freezer for a few minutes (I am cutting them up in the summer, longer may be needed if you do them in the fall) until the frost on the outside of them disappears, then saw away! They get just a little soft and saw so much easier than frozen rock hard. I do not have a band saw like in the above picture. I bought an electric chain saw at a yard sale for 5 bucks and use that (no chain oil is needed, fish oil from the fish being sawed works fine) and made a wooden cradle to hold the fish stable. With this setup I can make carp steaks from about 40 carp an hour for turtle bait.
