I’m sure you can visualize many possibilities in your head, but if you go to Hamarikyu Gardens in Tokyo you can get an idea of how the shôgun did it back in the day. The general process sounds like it belongs in an ethnic joke book:
- Build a pond and a creek.
- Raise ducks in the pond.
- Hide an iron door and a giant net in the bottom of the creek.
- Lure the domesticated ducks into the creek using the sound of wooden boards. (I don’t know why ducks like this sound, but maybe that’s why we eat them, and not the other way around.)
- Wait for wild ducks to follow the domestic ducks into the creek.
- Pull up the door, scaring the bejeezus out of the ducks.
- Pull up the net, catching the ducks.
- Laugh heartily and retreat for wild escapades with concubines.
