SIZE:

An average of 1 m for 50 kg to 100 kg, up to 3.65 m for 320 kg.

LIFE EXPECTANCY:

Up to 50 years.

LIFE CYCLE:

It reaches sexual maturity at approximately 5 years for males, and 9 years for females.

Scientists believe that females spawn between February and May. Millions of eggs are laid and subsequently fertilized.

After 30 to 40 days of life, the Halibut’s left eye migrates to the right side and its body turns. It then becomes a flatfish. It, therefore, does not have that “little crooked look” it has had since its birth.

On the seabed, between 10 m and 2000 m deep.

Shrimps
Crabs
Marine worms
Other fishes

REGULATIONS:

Make way for other fish

In 1852, Moses Perley, a New Brunswick lawyer and businessman, fisheries observer, and journalist, wrote in a report that Halibut were so plentiful and so large, that Halibut fishermen avoided certain areas, otherwise their boats would fill up with fish too quickly.

Atlantic halibut is a Smarter seafood listed species.

BENEFITS:

LET’S COOK:

Firm texture, lean white flesh. Fewer bones (perfect for the less experienced).

Must be consumed within 48 hours when fresh, or within 4 to 6 months if frozen.

OUR CULINARY ADVICE:

Favour short cooking times to avoid drying out (15 minutes oven-baked, 2 minutes on each side when pan-fried).
Defrost in a mix of water and milk for 2 hours to give it back its soft and tender texture.
