Zander Non Native Invader Zander (Stizostedion lucioperca) are a member of the perch family but with the predatory feeding behaviour of the pike. Illegally introduced: zander have been illegally introduced into several fisheries. They were introduced originally (legally) into lakes at Woburn Park in 1878 and later into the Great Ouse Relief Channel. In very turbid canals, many of the native fish populations in the waters where zander have been illegally introduced have suffered greatly by the aggressive feeding of this top predator. It is still not clear whether natural fish populations of species such as gudgeon will ever fully recover.

Spined loach Endangered Status: Listed on the International Union for Conservation of Nature (IUCN) Red list of Threatened Species Listed on Appendix III of the Bern Convention and Annex II of the EC Habitats and Species Directive (3) The inclusion of this species on Annex II of the EC Habitats and Species Directive has resulted in an increase in interest in its conservation, and an obligation for member states to designate Special Areas of Conservation (SACs) in key areas where the spined loach occurs.

Pike Native -Not endangered Appearance: They have large bony heads with prominent forward/upward looking eyes, a broad flattened snout and a large mouth. The mouth contains a fierce arsenal of teeth, with rows of backward pointing, razor sharp teeth in the top jaw and larger needle-like teeth in the lower jaw. The head is mounted on a long, torpedo shaped body with fins being primarily rear positioned for fast acceleration. Individual marking patterns are unique to each pike, like fingerprints to humans. This olive and cream colouration helps the pike to camouflage itself, while it lies in wait for its prey. British record: 46lb 13oz (British record committee 2015) Lateral line scale count: 110-130 Lifespan: Up to 25 years but 10 to 15 years is more typical. We like pike because of their distinct and fierce appearance

Roach Native Common The roach (Rutilus rutilus) is the most abundant fish on the canal network. Appearance: the roach is a shoaling fish, silver in colour with grey-brown to orange fins. Roach can often be confused with rudd. To check, you can count the lateral line scales (rudd have 40-55), look at the shape of the mouth (rudd have an upturned mouth as they primarily feed at the surface) and make sure the front of the dorsal fin is in line with the pelvic fins (In rudd the dorsal fin is well to the rear of the pelvic fins). Size: above 1lb is a specimen British record: 4lb 4oz (British record committee 2015) Lateral line scale count: 42-45 (this is the dark row of scales along the central length of the body). Lifespan: 8 to 14 years

Lifespan: 10 years Appearance: Crucian carp are hump backed with a deep bronze or golden body. They have no barbels around the mouth, unlike the common carp and have a long convex dorsal fin.

Grass Carp Non native invader Appearance: Grass carp can be identified by a long slender cylindrical, almost torpedo shaped body with a low flat head and small upturned mouth. They are fully-scaled across the body and have a deep bronze appearance. They can be seen easily during the summer at the surface of the water, warming their backs with their distinctive torpedo shape. British record: 44lb 8oz (British Record Fish Committee January 2015) Lateral Line scale count: 42-43 (this is the dark row of scales along the central length of the fishes body). Lifespan: 10 to 15 years A non-native species introduced from Asia, some of first introductions to the UK were carried out as an experiment in weed control on the Lancaster Canal with British Waterways and Liverpool University. They spawn in water temperatures well in excess of 20 degrees C and therefore unable to breed naturally in the UK.
