European Eel Anguilla anguilla
The eel is a very long, narrow fish that can grow to over a metre in length. It looks smooth and lacks the obvious scales and gills of other fish. It is famous for both its slippery nature and its mammoth migration from its freshwater home to the Sargasso Sea where it breeds. Image: Mattia (iNaturalist).
River Lamprey Lampetra fluviatilis
The river lamprey is a primitive, jawless fish, with a round, sucker-mouth which it uses to attach to other fish to feed from them. They have long elongated eel-like bodies and can be recognised by their gills which open directly to each side of the head and form a line of seven gill holes behind the eye. Adults live in the sea and return to freshwater to spawn. Image: Hans Hillewaert (iNaturalist).
Spined Loach Cobitis taenia
The Spined loach possesses the ability to utilise intestinal breathing. This is a stop-gap measure that sustains the spined loach when the water around it is oxygen-poor. At the water's surface it swallows air that brings oxygen into the intestine. Image: Sergey Yeliseev (Flickr).

Efforts were made to assess the status of the smaller, 'non-stocked' species such as Minnow, Bullhead, Sticklebacks Lampreys and Stone Loach. Although there was a good response from some individuals, contacts with Angling Clubs were disappointing with very few bothering to send in records. There are currently about 18000 records on the SBIS Database. In an effort to improve our knowledge of these fish SWT ran the Suffolk Tiddler Survey in 2002. A checklist of the main freshwater fish species in England and Wales can be found here The Environment Agency and some water companies collect data on fish stocks in the major river systems.
