Where I fish in Holland the Owners of the water catch Zander, Pike, Eel and sell them to the local restaurants. The lake owners also make a kind of stew from the Rudd and Roach.
I once tried baked pike but cannot recommend it.
In Germany and Poland they eat Goose or Carp as their Xmas dinner - But at the just moment Bird dishes are just not popular.
Last week in Germany, I was told that even the chinese waiters were joking that the Chicken was really Cat - as bird flu is causing customers to avoid poultry.
