Bass (European Sea Bass)

By Alex Clayton · Updated 23 October 2026

Since 27 February 2026, the recreational bag limit for bass in England has been three fish per angler per day, up from two. You still cannot keep a single one between 1 February and 31 March.

Sea bass, European sea bass and plain “bass” are the same fish, Dicentrarchus labrax. Menus and fish counters say sea bass; UK anglers say bass. This page is about catching them, not cooking them.

It covers identification, where bass live through the year, growth, the current rules, the British records, the main methods and safe handling. It sits within our guide to UK sea fish species.

How to Identify a Bass (and Tell It From a Grey Mullet)

A silver fish of about a foot swings up a harbour wall. You need to know in seconds whether it is a bass, because that decides whether the size and bag rules apply and how you hold it.

Sea bass have a streamlined silver body, a darker grey-blue back and a white belly. Look for two separate dorsal fins, the first carrying 8 to 9 sharp spines. There are 57 to 65 scales along the lateral line, and young fish are often spotted. The gill covers have sharp edges, so keep your fingers clear.

Small shoaling bass are called schoolies, and most fish you meet inshore are far smaller than the 100 cm maximum.

The usual look-alike on UK shores is the grey mullet. Both are silver with two dorsal fins, so check these four features:

Feature	Bass	Grey mullet
Head and mouth	More pointed head, large mouth	Blunt head, small mouth with thick lips
First dorsal fin	8 to 9 sharp spines	Four spines
Gill cover	Sharp edges	No sharp edges
Typical behaviour	Active predator, hits baits and lures	Grazes and sieves food, notoriously fussy

If you are unsure, count the spines on the first dorsal before you do anything else. For other look-alikes, see our UK sea fish identification guide.

Where Bass Live in the UK, Season by Season

Bass are being recorded further north than they used to be. North Western IFCA notes the shift in recent years and says their distribution is strongly affected by water temperature.

Sea bass are recorded around all UK coasts. Records are still highest in the south and west, but the range is moving.

Within that range, bass are fish of the margins: estuaries, surf beaches, rough and rocky ground, and harbours. They tolerate brackish water and in summer will run up tidal rivers.

Their year follows a clear pattern:

Season	Where adult bass tend to be
Winter	Deeper offshore water
Spring	Moving inshore, and spawning (see the growth section below)
Summer to autumn	Beaches, rocks, harbours and estuaries

Adults shoal in early summer and move into coastal waters and estuaries. Juveniles stay in shallow inshore water for four to five years. In their first year they form large schools in the shallows, and they spend at least a year schooling before they first move offshore for the winter.

Best for: late spring to autumn, from beaches, rocks and estuaries. Skip if you want fish to take home in February or March, because 1 February to 31 March is catch and release only (see the rules section). For where and how to fish each type of mark, read our guide to bass fishing.

What Bass Eat and When They Feed

If you change only one thing, fish dawn and dusk. It is among the most common pieces of bass advice, and low light is when many anglers find bass feeding closest to the shore.

Bass are opportunist predators. North Western IFCA lists their diet as shrimp, crabs and other crustaceans, molluscs, squid, small herring and sand eels. Each of those points to a bait or lure:

Crabs and shrimp: peeler crab or soft crab on the hook
Sand eels: live or frozen eels, or slim soft plastics
Squid: squid strips, alone or tipped with fish
Small fish: lures with a baitfish profile

On busy marks, bass can learn to avoid lures and visible line, so many anglers fish a clear mono or fluorocarbon leader. Moving water matters too: surf, tide and estuary flows push food around, and bass hunt in that movement.

Bait is the simpler start; lures cover more ground. Our best bait for bass page goes into the detail.

Spawning, Growth and Why Bass Are Slow to Replace

It can take up to seven years for a bass to reach the 42 cm minimum size, according to North Western IFCA. The same fish can live to 25.

Maturity comes late. In Atlantic waters, males mature at about 4 to 7 years old and 30 to 40 cm. Females mature at 5 to 8 years and 36 to 46 cm. A fish just over the 42 cm limit may be a female that has not yet spawned.

Sources and regions give different spawning windows, so the safe summary is late winter to early summer. North Western IFCA describes adults moving inshore to spawn from March to mid-June. They spawn in batches, and the eggs float in open water and hatch in about three to four days at 13 to 14C.

The stock picture is mixed. The IUCN lists the European sea bass as Least Concern globally, while the Wildlife Trusts describe the regional stock around the UK as overexploited and declining.

Slow growth and late maturity are why the rules focus on size and the spawning season, and why many bass anglers return most of what they catch. The next section sets out exactly what those rules allow.

Bass Fishing Rules 2026: Bag Limit, Size Limit and Catch-and-Release Dates

Plenty of pages online still quote one or two fish a day. The limit changed in February 2026. Here is what the official sources say for recreational sea bass anglers in England:

Bag limit: three bass per angler per day, boat or shore, outside the catch-and-release period, under SI 2026/105, in force from 27 February 2026.
Catch and release only: 1 February to 31 March, by rod and line or handline, including from the shore. This applies in ICES divisions 4b, 4c, 6a, 7a and 7d to 7j, which in plain terms are the sea areas around the UK’s coasts (GOV.UK bass fishing guidance).
Minimum size: 42 cm, measured from the nose to the fork of the tail. Anything smaller goes back.
Nets: fixed nets cannot be used to take bass, and Eastern IFCA states that fixed or drift nets are not permitted for recreational bass fishing.
Nursery areas: extra restrictions can apply in designated bass nursery areas under The Bass (Specified Areas) (Prohibition of Fishing) Order 1990. Check GOV.UK and your local IFCA for areas and dates.

SI 2026/105 extends to all four UK nations, but the devolved guidance has not caught up in every case, so treat this table as a starting point:

Nation	Bag limit	Catch and release	Minimum size	Check with
England	3 per day	1 Feb to 31 Mar	42 cm	MMO (GOV.UK) and your local IFCA
Wales	Welsh Government guidance of January 2026 said two, pending legislation	1 Feb to 31 Mar	42 cm	Welsh Government (check current guidance)
Scotland	Current guidance not confirmed	Check	Check	Scottish Government Marine Directorate
Northern Ireland	Current guidance not confirmed	Check	Check	DAERA

Before you keep a bass

Check the date. From 1 February to 31 March, every bass goes back.
Measure nose to tail fork. Keep only fish of 42 cm or more.
Count your fish. Three a day is the maximum in England.
Check local IFCA byelaws and any nursery area restrictions.
Return the rest quickly, with wet hands and the body supported.

If in doubt, put it back and check your IFCA’s page before your next trip. For the full detail, see our bass fishing regulations page and our overview of UK fishing seasons.

How Big Do Bass Get? British Records

The British shore record bass is heavier than the boat record.

According to the Angling Trust BRFC sea fish listings, updated 18 June 2026:

Shore record: 19lb 12oz 0dr (8.958kg), caught in 2012 by John Stephenson Locker at Portsmouth Dockyard, Hampshire.
Boat record: 19lb 9oz 2dr (8.876kg), caught in 1987 by P McEwan off Reculver, Herne Bay, Kent.

The boat record has stood since 1987 and the shore record since 2012. Sea bass can grow to about 100 cm, but a fish takes up to seven years just to reach 42 cm, so most bass anglers catch are far smaller than either record.

If you land a big one, measure its length and take a quick photo before you slip it back.

How Bass Are Caught in the UK: Main Methods

Why does a surf angler with crab bait and a lure angler on a rocky point both catch bass on the same tide? Because bass eat both crustaceans and small fish (see the diet section above), and each method puts one of those in front of them.

UK anglers target sea bass in three main ways:

Lure fishing: surface lures, soft plastics and shallow-diving hard lures worked over rough ground, along rocks and in estuaries, often at dawn and dusk. Our bass lure fishing guide covers it in depth.
Bait fishing: peeler or soft crab, sand eel, squid or fish strip on a running ledger or similar rig, fished on surf beaches, in estuaries and from harbours.
Fly fishing: a niche option in shallow, clear water, where bass can be seen hunting.

With any method, a clear mono or fluorocarbon leader helps where fish are wary.

Lures suit mobile anglers who like to cover rough ground. Bait is the better start for beginners on beaches and estuaries. For rigs, tides and marks, see how to fish for bass.

The same rough-ground marks can also produce pollack and coalfish. In winter, when bass move offshore, many beach anglers switch to cod.

How to Handle and Release Bass Safely

Grab a bass round the back and you will learn about its first dorsal spines the hard way.

Wet your hands first, then hold the fish by the lower jaw and support its body with your other hand. Keep clear of the spiny first dorsal and the sharp edges of the gill covers.

Keep the fish in or close to the water. Unhook it quickly, and if you need to check it against the 42 cm limit, measure it on a wet surface rather than dry rock or a hot deck.

To release it, hold the fish upright in the water facing into the flow. Let it recover and swim off on its own rather than throwing it back.

This matters most from 1 February to 31 March, when every bass must go back, and for any fish under 42 cm. Many specialist bass anglers release most of their fish whatever the date, and a fish that took up to seven years to reach keeping size is worth returning in good shape.

Wet hands, jaw hold, body supported, quick release.

Frequently asked questions

How many bass can I keep in 2026?

In England you can keep three bass per angler per day from 27 February 2026, but none from 1 February to 31 March, when it is catch and release only. In Wales, Scotland and Northern Ireland, check current guidance with the Welsh Government, the Scottish Government Marine Directorate or DAERA before you keep a fish.

What size does a bass have to be to keep?

A bass must be at least 42 cm to keep, measured from the tip of the nose to the fork of the tail. Any fish under 42 cm must be returned. Measure on a wet surface and keep the fish close to the water while you check.

Is sea bass the same fish as bass?

Yes. Sea bass and bass are the same species, Dicentrarchus labrax, also called European sea bass. UK anglers usually just say bass, while "sea bass" is the name you see more often on menus and fish counters.

When do bass spawn?

Bass spawn from late winter to early summer, with timing that varies by source and region. North Western IFCA says adults move inshore to spawn from March to mid-June, which overlaps with the 1 February to 31 March catch-and-release period.

What is the British record bass?

The British shore record bass is 19lb 12oz (8.958kg), caught at Portsmouth Dockyard in 2012. The boat record is 19lb 9oz 2dr (8.876kg), taken off Reculver, Kent, in 1987. Both figures come from the Angling Trust's BRFC list updated in June 2026.
