Biology

Witch is common in the northern North Sea, west of the British Isles, in Icelandic waters and along the North American east coast. It is a right-eyed flat fish (both eyes on the right-hand side of the body) belonging to a group of fish known as the family Pleuronectidae. Witch spawn in summer, have a slow growth rate, and reach sexual maturity in 3-4 years. Witch on average live for about 14 years, but the maximum reported age is 25 years. The species is mainly found on soft sea bottoms, mostly clay or clean sand, around 100-400 m depth. Their main diet consists of crustaceans, worms, brittle stars and fish.

Management

Witch is mainly a bycatch species and as such the fishery is currently largely unmanaged. The only management of the fishery is under a combined total allowable catch (TAC) with lemon sole. Scientists are concerned this prevents effective control of single species exploitation rates and could potentially leading to overfishing of either species.
