In the NK (No Kill) zones of Carnia (Collegio #9) you must follow precise rules and hold the correct permits.
- The season generally runs from the last Sunday in March to 31 December; from October to December fishing is allowed only in the TRA zones.
- In the NK zones fishing is allowed only fly fishing and spinning, with a single barbless hook.
- With the NK technique, a single permit allows you to fish in all the waters of the region.
- Anyone using other techniques who wants to keep their catch cannot fish in the NK stretches: they may keep 4 brown or rainbow trout or 2 marble trout. Limits and sizes are listed on the E.T.P.I. website.
