In season

Fresh in spring and autumn.

SIZE:

Its shell can grow to 15 cm.

LIFE EXPECTANCY:

From 10 to 15 years.

LIFE CYCLE:

Mating takes place between May and June. Two or three weeks later, the females come together to lay their eggs in the same place. The eggs form a spongy, yellowish, sticky mass casing, sometimes called sea wash balls. Five to eight months later, juvenile whelks are born, 2 mm to 3 mm in size.

Bed and breakfast

Empty whelk shells are becoming a favourite home for hermit crabs.

The waved whelk’s body is white with black spots. Its shell is light-colored with a thin yellow coating. Its shape and color can vary. It has 5 to 8 spirals ending in a point. The opening of its shell is closed by a hard opercule found at the end of the whelk’s foot.

Coastal zone, up to 30 m in depth.

The waved whelk favours cold waters and sandy or rocky bottoms.

REGULATIONS:

  • Fishing effort management (number of traps, minimum whelk shell size of 63 mm).
  • Total allowable catch in certain fishing zones.
  • Fishing seasons.

As the waved whelk is not a fast-moving animal, it is more vulnerable to local over-fishing. It has been fished in the St. Lawrence River since 1940.

BENEFITS:

Rich in magnesium, iron, calcium, and in B and C proteins.

LET’S COOK:

Sold cooked, frozen, or preserved in brine or vinegar. Texture and flavour depend on how it has been prepared. In brine, it will have a finer iodized flavour. In vinegar, whelk will have a slightly tougher texture. Freezing tenderizes the product, giving it a softer texture.

OUR CULINARY ADVICE:

  • The waved whelk is like a giant snail. Instead of eating garlic escargots, why not try the local version with whelk?
  • Great as an appetizer, snack, or in a chowder.
