  • Pollock, fish in sticks

    Pollock swimming in the Exploramer aquarium.

    Also called lythe and lieu jaune, pollock belongs to the cod family but tends to live in the open sea.

    Unlike the Atlantic cod, with its mouth downturned to feed on the seabed, the pollock’s mouth is upturned since it feeds on swimming prey.

    Pollock is used to make crab-flavoured fish sticks.

  • Atlantic cod, an endangered species

    Atlantic cod swimming in the Exploramer aquarium.

    This species was overfished for many years. Today, it is endangered.

    The females, which are smaller than in the past, lay far fewer eggs and not many of the young survive. Nevertheless, the cod seems to be making a slight comeback in the Gulf of St. Lawrence.

    The biggest cod caught in Canada measured almost 1.8 m and weighed more than 90 kg!

  • Atlantic sturgeon, a living fossil

    Atlantic sturgeon swimming in the Biodôme aquarium.

    This primitive fish has rows of bony plates that look like shields.

    It belongs to one of the oldest living fish families. Sturgeon fossils more than 65 million years old have been found!

    The Atlantic sturgeon can grow to more than 2 m long, making it one of the biggest fish in the River. It is also one of species that live the longest (about 60 years).

    The sturgeon, whose status is near threatened, is a protected species.
