Welcome, it's Neatorama Collaboration Monday!
The Sydney Morning Herald had this one featuring Ukai, a traditional fishing method that has been used in Japan for 1300 years, or so they say. In Ukai, you use a sea bird, a comorant, on a leash to fish for you.
It's pretty disgusting and so the practice is pretty much limited to a small group of traditional fishermen. Why?
This page has more detail, including the note that they have to prevent the bird from eating the fish somehow. So they put a small ring around its neck, and once the bird catches something...
..you make it cough up the goods.
According to Neatorama's Alex, the practice was originally founded in China.
