Bait, Bait Use and Aquatic Invasive Species

Bait use in Aquatic Invasive Species Control Zones - updated February 6, 2020.

When using bait in an AIS Control Zone, only bring the live bait you are going to use on that water body. Any bait you take with you to an AIS Control Zone MUST be discarded BEFORE you leave the shore if it:

  • is live
  • has been handled (i.e., hooked) or
  • has come into contact with surface water from the control zone

Anglers cannot kill live bait in an AIS Control Zone and then remove it for any future use.  

These live-bait disposal requirements applies even if you have a valid 3-day live bait fish-transfer-and-use receipt. Also all water from the bait container must be drained before leaving the shore.

Only commercially-supplied dead bait used on an AIS Control Zone can be retained by anglers for future use IF it has NOT:

  • been handled (i.e., hooked) or
  • come into contact with surface water

Revised: January 19, 2021


Possession of crayfish is prohibited in Manitoba. Crayfish, or what may commonly be referred to as "crawdads" or "crawfish," cannot be used as bait.

The Manitoba Fishery Regulations, 1987 Section 14(1), under the federal Fisheries Act

What can be used as bait?

Please refer to the Manitoba Anglers' Guide for more information about bait and bait use.

It is also NOT recommended to purchase frozen fish from a grocery store to use as bait. In some cases, harmful diseases not killed by the freezing process, can spread to native fish.
