A rare herring-like fish that is protected in the UK and must be returned at once; it is bigger than twaite shad and only a few rivers still hold it.[1]

How to recognise it

  • Notched upper jaw with a dark spot behind the gill opening, sometimes followed by small blotches.[2]
  • Many long, thin gill rakers (85 to 155), longer than the gill filaments; twaite have fewer and shorter.[2]
  • More than 70 scales along the lateral line; grows to nearly 5lb, larger than twaite.[1]
