BARBEL


BARBEL

Found in a few Eastern and Southern English rivers - where it favours swift gravelled streams near weirs - or deep fast currents between the pylons of bridges. There shoals of Barbel swim powerfully against the flow - hugging the bottom with their flattened bellies - and feeding on worms - insect larvae - small fish and vegetable matter. The Barbel is olive-green on the back - silvery underneath. It has a crescent-shaped mouth with four barbels - and smallish scales.

GUDGEON


GUDGEON

This small fish is abundant in England - except in the Lake District and in Cornwall - especially over the gravelly stretches of rivers. It keeps to the bottom - grubbing for insect larvae - worms and small shellfish. The body is dark - with a longitudinal row of squarish blue-black blotches on each side. The tail is forked - the scales rather large. It can be distinguished from similar fish because it has only two barbels.

COMMON CARP


COMMON CARP

It grows large in lakes and in the quiet reaches of rivers - but may remain tiny in small ponds. The body is thick and deep - olive-bronze in colour - with large scales; the mouth bears four barbels - two small - two large; the dorsal fin is long and concave - highest at the beginning. The Carp feeds mostly on vegetable matter - but worms, insect larvae and shellfish are also eaten. It has a reputation for caution and cunning.

CRUCIAN CARP


CRUCIAN CARP

Found mostly in Eastern and South-Eastern English still waters. It is olive-brown - deeper and thicker than the Common Carp - from which it can be distinguished by its long - convex dorsal fin - highest in the middle - and by having no barbels. The short anal fin and the long dorsal are the most obvious differences from the Bream. A variety of this fish - called the Prussian Carp - is often found in garden ponds. The Crucian is not as large as the Common Carp.

GOLDFISH


GOLDFISH

A fish from the Far East which has been introduced in many ornamental ponds; it often reaches sizes rivalling those of the Crucian Carp - which it closely resembles in the wild state (even in colour). It must not be confused with the golden varieties of the Carp - Tench or Orfe - frequently seen in aquaria and garden ponds. Fish breeders have evolved many varieties of Goldfish with an astonishing assortment of freakish colours and appearances. The Goldfish may reach 4 or 5 lbs. in weight.

DACE


DACE

This slim and sprightly fish is widespread in England and Wales. It favours fast water - where is can be seen in active pursuit of insects and crustaceans - or rising to flies. The body is silvery - with a dark brownish or blue-green back; the lower fins seem yellowish or pale pink; the dorsal and anal fins are concave ("Dented Dace" - say fishermen - so distinguish it from Curved Chub); the anal fin is short - with 7 to 9 rays. It is usually well under a pound in weight.

CHUB


CHUB

Common everywhere in Britain except in Northern Scotland, West Wales and Cornwall; not found in Ireland. It likes running water - preferably under trees - where it feeds on insects - small fish and frogs - fruit fallen in the river - worms and shellfish. The back is dark - the sides silvery - usually with a faint brassy tinge; large mouth with whitish lips; tail often with a black edge; the dorsal and anal fins are convex the lower fins bright red.

BLEAK


BLEAK

Sometimes called the Freshwater Sprat - from its close resemblance to that sea fish - both in size and appearance. In Summer - it dashes here and there near the surface in the slow-flowing rivers of Eastern and Southern England - in pursuit of insects and crustaceans - or following pieces of bread; in Winter it retires to deep water. The body is compressed - green on the back - silvery on the sides and belly - the fins whitish; the anal fin is rather long (having from 15 to 20 rays) - unlike that of the Dace (from 7 to 9 rays).

ROACH


ROACH

The Roach - probably the most popular fish among freshwater anglers - is found in most kinds of water in Britain - except Northern Scotland. The back is dark green - blue or brown - the sides and belly silvery. The concave dorsal fin begins above the base of the ventral fins. The anal fin is concave - short - and bright red. The mouth is small - with a projecting upper lip. It prefers gently flowing weedy water - and feeds on small creatures and vegetable master.

RUDD


RUDD

Widespread in England, Wales and Ireland (where is is called "Roach") it is found especially in ponds and lakes - or the quieter reaches of rivers. It resembles the Roach - but a yellow, golden or brownish tinge covers the silvery sides; the dorsal fin is well behind the beginning of the ventral fins - and the lower lip projects (unlike the Roach's). The fins and sometimes even the lips are red. It feeds higher up in the water than the Roach - taking flies and also shellfish - worms and plant material.

TENCH


TENCH

Distributed irregularly over the British Isles. It is very tenacious of life - and easily transported alive in damp moss. It prefers weedy and muddy ponds and meres - where it grubs at night in the mud for shellfish, worms and vegetable matter. The colour varies from olive to blackish; there is also a golden ornamental variety. The eye is small and red - the fins rounded - and there are two little barbels on the side of the mouth.
