About the witch

The witch is an oval, right-eyed flatfish, light brown to greenish-grey with darker fins, a small head, rough skin and a straight lateral line. It is a cold-water fish of deep water over sand and mud, found down to over 1,000 metres. British Sea Fishing gives its size as up to 2 ft and 5 lb. It is taken commercially by bottom trawling, but a rod-and-line catch is very rare. So the witch is one of those fish that most anglers will read about rather than catch. Our record does not mark it as a Sussex species. There is no boat record for it either: the official list shows the boat weight record as unclaimed, with a qualifying weight of 12 oz. If you do catch something that looks like one, check the markings, the rough skin and the straight lateral line. We would rather tell you plainly that it is rare than promise you a chance of one. Think of it as a fish for the curious, and for anyone who likes to know what lives in the deep mud below the boat.

On the boat

The witch is a very rare rod-and-line catch, according to British Sea Fishing, and it is taken commercially by bottom trawling. It lives in deep water over sand and mud. Our record gives no months for Britain or Sussex and no angling method, so we cannot say how or when to target one from a boat.
