The Atlantic halibut (Hippoglossus hippoglossus) is the largest species of flatfish preferring temperate to Arctic waters with sand, gravel or clay bottoms. The Atlantic Halibut is a popular food fish throughout the world yet the commercial fishing of the species has significantly declined due to a slow rate of growth and intensive overfishing. The species does not reach maturity until late in life between 8 to 11 years. Atlantic Halibut size is not age-specific, but rather tends to follow the abundance of food and can reach lengths of 15ft and weigh over 300Kg. Since the commercial fishery has declined due to the population collapse of the Atlantic Halibut it has been a popular fish for Aquaculture. It has been farmed in multiple countries including Canada, Norway, Scotland and Iceland.
