Aquatic Invasive Species
The intentional or accidental introduction of fish or other aquatic organisms from one lake or stream to another can negatively affect local fish populations through competition, disease, or genetic changes. No one is allowed to release live fish into the waters of the province, except under a license issued by the Department of Fisheries and Oceans. Unwanted fish species can be accidentally spread by releasing unused live bait.
Because of the potential threat to local fish populations, it is also illegal to use certain species as bait or to possess them for bait (whether alive or dead). These include bass, bullhead, white perch, yellow perch, goldfish, pickerel, or any fish not taken from provincial waters.
Public notification
Mandatory retention
Fisheries and Aquaculture is taking further action to slow the spread and prevent further harm from aquatic invasive species. Effective 1 April 2025, mandatory retention has been implemented for Chain Pickerel and Smallmouth Bass in the following areas:
- It is mandatory to retain all Chain Pickerel in all waters of Nova Scotia.
- It is mandatory to retain all Smallmouth Bass in all waters east of Highway 102 from its junction with Highway 104, to Highway 118 to Highway 107 to Highway 328 (Ross Road) near Upper Lawrencetown.
- It is mandatory to retain all Smallmouth Bass caught in the west branch of the LaHave River, upstream from the confluence with the main branch, including all lakes and tributaries.
This approach is not intended to eradicate the populations, rather, it is a proactive, tangible action to reduce the rate of spread throughout the province. As with any fish, Chain Pickerel and Smallmouth Bass should be euthanized in a humane manner.
If you catch a Chain Pickerel or Smallmouth Bass in the areas listed:
- Do not release it, or any parts of it.
- Quickly and ethically euthanize the fish.
- You may retain the fish for personal use; however, its sale is prohibited.
