Etymology
from the old Scandinavian "thornbutr"

Turbot is particularly sought after from April to August, just before its spawning period, when it is fattest. 

Turbot is a deep water fish with delicious flesh, belonging to the same family as halibut, namely pleuronectidae (flat fish). Recognizable by its lozenge shape, it measures between 40 and 80 cm in length. When a meter or less in length, it is considered a young turbot. 

It is one of the finest ocean fishes. It is fished in the Atlantic and, to a lesser extent, the Mediterranean.
