The act of taking a 2-3 foot diameter net, on the end of a 10-15 foot pole, attaching a dip to the end of the pole opposite the net, wherein said dip inserts the net end into a raging, dangerous river while perilously perched on rocks hanging from the side of a canyon, hoping to catch salmon migrating upstream in said net.  It has been known for 30 salmon to be caught in 2 hours, but not uncommon for 2 salmon to be caught in 30 hours.  The intelligence of dips can be observed by how securely they are tied off to canyon rocks, to preserve their bodies for burial should they fall into said river.  Dipnetting is most frequently used when referring to the Copper River, though “dipnetting light” is allowed on a few other Alaskan rivers.  Dips must be Alaskan residents.  (Please note; author is a mid-level intelligence dip, but don’t tell his wife.)
