MSC – Waterhen Lake walleye and Northern pike commercial gillnet fishery
Manitoba is a large producer of fish, spread over dozens of lakes. Sustainability is hampered by a lack of assessment and enforcement. Most of the lakes suffer from a lack of even the most basic information about fish stock status. In larger lakes with some index of population health, the management system has not been set up to adjust for allowable catch limits or to reflect population levels.
For example, Lake Winnipeg has a fixed quota that doesn’t change in accordance with the fish population being harvested. Additionally, three species of fish are managed under one quota, which can lead to a wasteful practice called high-grading whereby lower value species are thrown back dead or dying, to allow fishers to keep more of the more valuable species.
Population: Catch monitoring needs to improve, and high-grading1 needs to be addressed.
Bycatch: N/A
Habitat: N/A
Management/Monitoring: Improving the management of Manitoba’s fisheries requires a long-term incremental approach. The current Manitoba government is committed to improved management, with several initiatives underway to improve catch monitoring and to better understand the health of populations at a lake-by-lake level. While one lake has already achieved eco-certification through the Marine Stewardship Council, several others recently announced that they have entered the MSC process. SeaChoice will continue to work with the Fisheries Branch and the seafood supply chain to push for further improvements.
Markets: In addition to addressing the fishery management issues identified above, SeaChoice is working with major retailers and other buyers of these species to encourage better sustainability practices through market measures, such as preferential purchasing from responsible producers.
