A field guide, not a tick-list

Carp

Cyprinus carpio

The fish that built modern UK commercials — and still the one most anglers actually want to hold. Commons, mirrors and leathers, from mid-doubles to the fish of a lifetime.

F1

Cyprinus carpio × Carassius

The engine of UK commercial sport. Fast, fussy, and often happier midwater than on the deck. If you can catch F1s well, you can catch most things on a day-ticket lake.

Tench

Tinca tinca

The green knight of stillwaters. Tench patrol silt, lily beds and quiet margins — a summer fish with a pin-prick bite and a dogged fight.

Bream

Abramis brama

The slab of stillwaters and slow rivers. A feeding shoal of bream can fill a net; a wary pit bream can empty an afternoon.

Roach

Rutilus rutilus

The silver that made canal and river fishing. A proper roach — brick-red fins, clean scales, that violet eye — is still one of the most satisfying fish you can catch.

Rudd

Scardinius erythrophthalmus

A surface-minded silver of stillwaters and canals. Upturned mouth, golden flank, and a habit of taking on the drop.

Crucian carp

Carassius carassius

The shy gold of estate lakes and a few careful commercials. Tiny bites, light tackle, and a fish that rewards sitting still.

Dace

Leuciscus leuciscus

The small, quick silver of clean rivers. Stick float, maggot, and a strike that has to be faster than the fish.

Gudgeon

Gobio gobio

The little barbelled fish of canal tracks and river gravel. Maggot, whip, and a reminder that not every session has to be a double-figure carp.

Ide

Leuciscus idus

A stocked silver of some UK commercials and park lakes. Chub-like, willing, and often happier off the bottom than on it.

Barbel

Barbus barbus

The prize of running water after 16 June. A fish of creases, gravel and a bait put in the right seam — not a stillwater method with a bigger lead.

Chub

Squalius cephalus

The opportunistic river fish. Bread, cheese, maggot, a chubber float or a quiet leger under a bush — and they will still surprise you on a canal.

Perch

Perca fluviatilis

The striped hunter of lock mouths, snags and commercial features. Worm, maggot, and a small lure will all catch perch.

Pike

Esox lucius

The stillwater and river predator. Deadbait or lure, wire trace, forceps, and a fish that demands proper unhooking — not a casual maggot session.

Zander

Sander lucioperca

A non-native predator of some rivers, drains and stillwaters. Treat the fishing like a careful pike–perch hybrid: wire or heavy fluoro, welfare, and the local rules.

Eel

Anguilla anguilla

A declining, legally protected traveller. If you catch one, unhook it quickly and put it back. Do not keep eels.

Catfish

Silurus glanis

A heat-loving imported cat of some UK stillwaters. Huge, powerful, and a welfare job — only fish waters that actually stock them.
