Trout Regulations

License Requirements:

  • A resident or nonresident fishing license is re­quired of all persons who take or attempt to take fish, including trout, un­less otherwise exempt.
  • A trout license (stamp) is no longer required because it is included in the resident or nonresident fishing license.

Trout Stocking Seasons:

See map and description of each state-designated trout area. Anglers may fish for and harvest trout any time during the year, unless otherwise specified by area.

Method of Taking:

  • It is unlawful to take fish from state-designated trout areas dur­ing trout season by any means except one rod and reel (or one pole and line).
  • Trout caught and placed on a stringer or otherwise held in pos­ses­sion cannot be released later (no culling).
  • All trout in possession must be kept on a stringer marked with that angler’s name and fishing license number. All anglers must have their own stringer.

Daily & Size Limits:

  • Daily limit is six rainbow trout in all state-designated trout areas except in portions of the Blue River, the Lower Illinois River and the Lower Mountain Fork River. (See maps and descriptions on Trout Regulations and Trout Area Information.)
  • There is no minimum size limit for rainbow trout at any state-designated trout area except in portions of the Lower Illinois River and the Lower Mountain Fork River. (See maps and descriptions on Trout Regulations and Trout Area Information.)
  • Daily limit for brown trout is six with no minimum size limit, except at the Low­er Moun­tain Fork River and Lower Illinois River where the daily limit is one; size lim­it: 20-inch min­i­mum, with a pos­ses­sion limit of two af­ter the first day.

Possession Limit:

No person shall have in his possession in the field more than one daily limit of any trout species. After the first day, no person shall have more than 12 rainbow trout and 12 brown trout in his or her possession, except at the Low­er Moun­tain Fork River and Lower Illinois River where the possession limit for brown trout is two. Non­res­i­dents shall not have more than two days’ limit of any trout species upon leaving the state.

Artificial Flies and Lures Defined:
