When using nets and traps, be aware of the legal collection methods and which species can be collected legally. The following diagrams show examples of common species and attributes to look for when identifying them. Must have a valid sportfishing license.
Legal collection methods
Seine, cast net, trap, dip net.
Legal species
Shiner, chub, dace, minnow, sucker, crayfish.
Illegal species
Sunfish, bass, catfish, pike.
Additional illegal species can be found in the Indiana Fishing Regulations Guide.
Minnows and crayfish are often collected from public waters for anglers to use as bait. In addition to collecting fish and crayfish with legal sport fishing methods (e.g., hook and line, trotline, or bowfishing where legal), nets like seines, cast nets, and dip nets as well as small traps can legally be used. Below is a summary of the rules on using nets and traps for the collection of certain fish species and crayfish.
Specific information on rules can be found in 312 IAC 9-7-15 Minnow Authority and 312 IAC 9-9-2 Crayfish Authority. (Article 9).
Key points
- Anglers must have a valid sport fishing license to participate in fish netting and trapping.
- Anglers can collect an unlimited number of minnows and crayfish at any time of the year, but they cannot be sold. Anglers must not transport beyond the limits of this state more than 100 minnows or crayfish in a 24-hour period unless they have a bait dealer’s license from the DNR.
- Anglers can release fish back into the waters in which they were collected, but gizzard and threadfin shad and invasive species can not.

- Our district fisheries biologists are available to answer collection questions.

|---|---|---|
 Cast net | Cast nets cannot be more than 20 feet in diameter and must not have stretch mesh* larger than ¾ inch. | Cast nets must not exceed more than 20 feet in diameter and must not have stretch mesh larger than ¾ inch. |

 Seine | Seines cannot be more than 12 feet long and 4 feet deep and must not have stretch mesh larger than ½ inch. | Seines cannot exceed 30 feet long and 6 feet deep and must not have a mesh size larger than ¼ inch bar mesh. |
