Warm Water Regulations

General Information

Warm-water fish, also known as spiny-ray fish, include species such as largemouth bass, smallmouth bass, walleye, catfish, sunfish, white bass, and striped bass. Many of these fish occur wild in self-sustaining populations throughout New Mexico. Some of these populations depend on supplemental stocking. Each year, NMDGF stocks thousands of largemouth bass and channel catfish and millions of walleye fry to increase and improve angling opportunities.

Bait and Baitfish

Possession of and use of any baitfish while fishing is illegal, except as defined below. Baitfish may not be used in Special Trout Waters, Bitter Lake National Wildlife Refuge or Bottomless Lakes State Park. Bluegills and sunfish (genus Lepomis) taken legally by angling may be used as live or dead bait in the water where taken.

Commercially packaged and processed dead fish are not considered baitfish and are approved for use in all waters where the use of bait is legal. Roe, viscera, and eyes of game fish taken legally may be used in all waters where the use of bait is legal. Chumming is allowed in all waters, except Special Trout Waters. Goldfish or bullfrogs (including larval stages, i.e. tadpoles) may not be used as live or dead bait in any waters. Salamander larva (waterdogs) may be used in all waters where the use of bait is legal.

Trotline or Set Line Use

A trotline (throw line, limb line, set line, jug line, or “Yo-yo” line) is a line without a rod or reel attached. It does not need to be handheld nor closely attended. Trotlines are limited to 25 hooks. Trotlines belonging to two or more people may not be joined or tied together. Anglers may not fish with more than one trotline. Anglers may not check, pull up, or tamper with the trotline of another person. Any person using a trotline must attend it personally at least once every calendar day and remove or release all game fish that are caught.

A person fishing with a trotline must attach an identification tag that is visible above the water line. The identification tag must list the angler’s Customer Identification Number (CIN). Anglers 11 years of age and younger must list their Customer Identification Number (CIN) or their name and date of birth on the identification tag.

Trotlines may be used to take game fish only in the river reaches and lakes listed on page 25.
