UK Fish Species Guide

The UK holds more than 50 species of freshwater fish and a significant number of regularly caught sea fish. Each one has different habitat requirements, seasonal behaviour, preferred baits, and handling considerations. The guides in this section cover all of them properly – not just what they look like, but where they actually live, when they feed, and how to catch them.

UK Freshwater Species

UK freshwater fishing splits into three broad groups: coarse fish, game fish, and predators – though the lines blur. Most coarse fish are fished under a general Environment Agency rod licence; game fish (trout and salmon) typically require additional permits. Predator fishing for pike, perch, and zander is coarse fishing and follows the same licence and close season rules.

Predators

Predatory species are a significant draw for UK anglers. Pike are the largest and most widely distributed freshwater predator; perch are arguably the most accessible; zander have expanded their range significantly since their introduction in the 1960s.

Coarse Fish

Barbel, bream, roach, chub, carp, tench, and dace make up the backbone of UK river and stillwater coarse fishing. Each has a distinct character – barbel fight harder than almost anything their size; a good roach from a clear chalk stream is one of the most satisfying catches in UK fishing; carp have spawned a dedicated commercial sector that barely resembles the rest of coarse fishing.

Carp

Carp fishing has grown into its own dedicated branch of UK angling, with several distinct strains found across commercial fisheries and traditional waters.

Game Fish

Brown trout, rainbow trout, sea trout, and Atlantic salmon. Game fishing is primarily a permit or club membership pursuit. Fly fishing is the dominant technique, though spinning and bait fishing are permitted on many waters under the right conditions.

UK Sea Fish

UK sea fishing covers a huge variety from shore fishing for bass and wrasse to boat fishing for tope, ray, and cod. The species you can realistically target depend heavily on your coastline – Welsh bass fishing looks nothing like the cod fishing available to anglers on the Yorkshire coast.
