How do you make your fish cakes, gnu? With salt cod,haddock, or hake (soaked-boiled in water to remove the salt) or fresh groundfish? I find the taste quite a bit different. Some folks use canned Chicken Haddies, aka Finnin Haddies, (fish). They (boil and mash potatoes, add diced onion and canned Chicken Haddie and mash it all together and pan fry it - or make fish cakes.
