Nova Scotia is strengthening its fishing regulations to slow the spread of invasive species, with new rules requiring anglers to retain and euthanize chain pickerel and smallmouth bass in designated areas.
As of April 1, 2025, it is mandatory to retain all chain pickerel caught anywhere in Nova Scotia.
Smallmouth bass must also be retained in certain areas, including all waters east of Highway 102 from its junction with Highway 104 to Highways 118, 107, and 328, as well as the west branch of the LaHave River, upstream from its confluence with the main branch.

These measures follow concerns over the impact of invasive fish on native species. Chain pickerel and smallmouth bass compete with local fish, spread disease, and alter ecosystems. While eradication is not the goal, officials say reducing their numbers can slow their expansion.
Mandatory Retention Guidelines
Anglers catching chain pickerel or smallmouth bass in regulated areas must:
- Not release the fish or any of its parts.
- Euthanize the fish quickly and ethically.
- Retain the fish for personal use if desired, but selling it is prohibited.
