Species to prefer

Atlantic halibut, a giant flatfish

In the Gulf of St. Lawrence, halibut is usually fished with longlines, where a line fitted with a series of hooks is placed on the sea floor to avoid accidentally catching other species and deteriorating the natural environment.

Rainbow trout

Very popular among recreational fishermen, the rainbow trout is also a good choice when produced commercially especially when reared in total confinement, in fish pens that have no contact with the natural environment.

In the Gulf of St. Lawrence, Northern shrimp is fished with trawls, a method that has little impact on the aquatic habitat and minimizes accidental catches of other species. This is the first Canadian fishery to received Marine Stewardship Council certification as a sustainable fishery.

Species to avoid

Atlantic cod

Atlantic cod was fished for a long time, so much so that it almost disappeared from Gulf of St. Lawrence waters. Protection measures were taken but the cod population is still struggling to recover.

Pollution, invasive species, urban sprawl and pleasure boating are all factors contributing to the deterioration of the habitat of the copper redhorse, which has difficulty reproducing.
