Fish
 |
Fish (plural: fish) are an aquatic group of vertebrates which live in water and respire (get oxygen) with gills. They do not have limbs, like arms or legs, and they do have digits (fingers & toes). This is a definition which does not quite work: some amphibia also live in water and have external gills, but they are not fish. They are usually covered with scales and have two sets of paired fins and several unpaired fins. |

Bream - Abramis brama Colin W A fairly large, deep-bodied, rather diamond shaped fish with dark bronze back, bronze flanks and dark fins. Young can be confused with silver bream (Blicca bjoerkna), also readily hybridises with Roach. |

Pike - Esox lucius John F Below the suface of the canal you just see the image of the Pike with it's eye on the left. Pike cannot be mistaken for any other fish in British waters. From their mottled green appearance, sleek body and armoury of razor sharp teeth, the whole body of the pike is designed for hunting down live fish. Pike are ambush predators, mounting a lightening quick attack that lasts only a few seconds. All of the fins of the pike are positioned well back on the body, giving them maximum acceleration from a standing start when lunging at prey. One of the most widespread of all freshwater fish. Found throughout Northern Europe and North America, the pike is a fish of the temperate waters of the Northern Hemisphere. In the UK, pike can be found in every county of England, except Cornwall and throughout most of Scotland, Wales and Ireland. |

Roach - Rutilus rutilus John F The roach is a small fish, often reaching no more than about 35cm, maximum length is 45-50cm. The body has a bluish silvery colour and becomes white at the belly. The fins are red. The number of scales along the lateral line is 39-48. The dorsal and anal fins have 12-14 rays. Young specimens have a slender build; older specimens acquire a higher and broader body shape. The roach can often be recognized by the big red spot in the iris above and beside the pupil. Colours of the eye and fins can be very pale, however, in some environments. |
