saithe's habitat is in the North Atlantic Ocean, from the Barent
Sea to the Biscaya Bay, and around Iceland and Greenland, and
from the Hudson Bay to the coasts of North Carolina, USA. In
Icelandic waters it is more common in the warmer seas off the
southwest and south coasts than of the north coast. It is found
from the surface to the ocean floor, down to 450 m, but most
commonly at 200 m. Its ideal temperatures lie between 4°C and
12°C. It migrates in great schools too feed. Tagging has
confirmed the great migration distances of this species. Its
feeding habits depend on its size. The fries feed on worms and
crustreceans, while the larger fish feed on capelin, sand eel,
other fishes and krill. The saithe fries feed other fishes and
birds, and the larger fishes sharks and toothed whales. During
the first year the saithe grows fast. At the age of 4-5 months
it is 5-6 cm long and seven months later 10-25 cm. Two years old
it measures 28-42 cm and heads for deeper waters. It reaches
puberty 4-7 years old. It is
