LRF Fishing (Light Rock Fishing) Explained

By Alex Clayton · Updated 23 October 2026

LRF fishing (light rock fishing) means catching sea fish on very light lure tackle: jigheads and lures of a few grams, up to about 7 or 8g, worked around harbours, piers and rocks. The kit is cheap, and the fish live tight to structure in shallow water close to shore.

It isn’t only about gobies and blennies, either. Pollack, scad, mackerel, wrasse and schoolie bass all take LRF lures.

The hard part is the advice. UK guides disagree on rod ratings, and few of them cover what you can legally keep or how to handle small fish. This guide works through it in eight steps, from choosing a rod to your first session on the harbour wall. For other ways to fish the coast, see the sea fishing techniques hub.

Step 1: Choose an LRF Rod (and Make Sense of the Conflicting Specs)

Cast a 2g jighead on a standard 20-40g spinning rod and the lure drops short, while a goby can strip the tail off your worm without the tip twitching. That is why the rod is the first thing to get right in LRF fishing.

UK sources don’t agree on the numbers. British Sea Fishing puts LRF rods at 6 to 9ft and up to about 7g, with the lightest rated 0.5-5g. Voyagers Hook suggests 6 to 8ft at 0.5-10g. Street Fishing London caps the rod at 8g and treats heavier lures as light game fishing.

The numbers describe one range. A 0.5-5g rod suits jigheads under 2g on a calm harbour. A rod nearer 8-10g copes with small metals and a stiff breeze.

The tip is the other choice to make:

Solid tip: shows the tiniest plucks and gives a wary fish little resistance. Best for mini species.
Tubular tip: hollow, with more power for working small metals. Better if you expect mackerel, scad and pollack.

A shorter rod is easier tight to a harbour wall, and a longer one reaches over weed or out from rocks.

If you are buying one LRF rod, start with 7 to 8ft rated around 0.5-7g or 1-8g, with a solid tip for mini species or a tubular tip for mid-water fish.

Step 2: Match a Small Reel With Braid and a Fluorocarbon Leader

If you already fish for perch with lures or the drop-shot, check what you own before you buy. Ben Bassett, writing for Street Fishing London, points out that UK perch lure rods, reels and braid can double for LRF.

The reel is the easy part. British Sea Fishing, Voyagers Hook and Street Fishing London all recommend a 1000 or 2000 size fixed-spool reel, with 2500 as the upper limit. Rinse it in fresh water after every sea session.

Line is the real decision:

Setup	Strengths	Drawbacks
Braid (PE 0.2-0.6, roughly 4-8lb) with a 4-8lb fluorocarbon leader	Longer casts, better bite feel	Needs a leader knot
Light mono (3-8lb) straight through	Cheap, simple, nothing to join	Less sensitive

With braid, Street Fishing London’s setup is about 6ft of 4lb fluorocarbon leader joined with an FG knot. The leader also takes the rock abrasion that would cut bare braid.

Start on mono if you want to keep costs down, and move to braid once you know LRF is for you. The braid vs mono guide covers the trade-off in more depth.

Step 3: Stock a Small Box of LRF Lures, Jigheads and Hooks

Street Fishing London warns that it is easy to get preoccupied with scented lures, and that on a warm day they often aren’t needed. Your first box of LRF lures can be small.

Hook sizes follow the UK convention, where a higher number means a smaller hook. Size 10 is the all-rounder.

Item	Size	What it’s for
Light jigheads	Under 2g, size 8-10 hooks	Most mini species on the bottom
Jigheads with larger hooks	Size 6-8	Marks where wrasse are likely
Soft plastics	1-3 inch worms, grubs and small shads	Everyday use on jigheads and drop-shot
Scented worm-style lures	One small pack	Slow days when fish won’t commit
Drop-shot hooks	Size 8-12	Holding a lure still beside structure
Sliding weights	A few grams to 10-15g	Carolina rigs and deeper water
Small metals or spinners	5-10g	Mackerel and scad

Jigheads across the whole 1-7g range have a place, but sub-2g heads catch most fish on a harbour wall. Go heavier only when wind or depth stops you feeling the bottom.

Many scented worm-style lures are biodegradable, which matters when you lose a few to the rocks.

Best for a first session: a pack of sub-2g jigheads and a pack of small worms. Skip the big lure sets until you know what your local fish want.

Step 4: Tie the Three LRF Rigs Worth Learning First

Learn three LRF rigs and you can fish almost any harbour wall. Each one solves a different problem: covering ground, holding still, or getting through weed.

Jighead rig

Thread a soft plastic onto the jighead so it sits straight.
Cast or drop it in and let it sink to the bottom.
Work it back with small lifts and shakes, or a slow, steady retrieve.

Use it when you want to search water quickly. Its weakness is rough ground, where an exposed hook snags.

Drop-shot rig

Tie a size 8-12 drop-shot hook to your leader with a Palomar knot, leaving a long tag end.
Pass the tag back down through the hook eye so the point stands out from the line.
Clip a drop-shot weight with a pinch swivel to the tag end.
Nose-hook a small soft plastic.
Fish it tight to the bottom with tiny movements of the rod tip.

Use it to hold a lure beside walls, pillars and pontoon posts. It is slow for covering water, so pair it with a jighead. The drop-shot rig guide covers the setup in more detail.

Carolina rig

Slide a small bullet weight and a bead onto the main line.
Tie on a swivel.
Add 30-50cm of fluorocarbon.
Tie on a small offset hook and rig a worm weedless.

Use it over weed and broken ground. A Texas rig is the close cousin, with the weight sitting right on the hook. See the Carolina rig guide for more.

Start with the jighead. Add the drop-shot the first time fish follow your lure but won’t take it.

Step 5: Match Your Lure and Rig to the Species You Can Catch

Fish one rig the same way every trip and you will catch the same few species. A UK harbour can hold rockling, blennies, gobies, sea scorpions, dragonet, topknot, eelpout, shanny, butterfish, pogge, lesser weever and small wrasse, with pollack, scad, mackerel, bass, flounder, gurnard and gilthead bream as bonus fish.

Match the presentation to where each group feeds.

Species group	Where they sit	Lure	Rig
Gobies, blennies, shanny, sea scorpions	Tight to walls and rocks	Small worm or scented plastic	Drop-shot or light jighead
Small wrasse	Weed and rock edges	1-2 inch worm	Weedless Carolina or jighead, size 6-8 hook
Rockling and pouting	Deeper harbour water, low light	Scented plastic	Light jighead on the bottom
Pollack, scad, mackerel, schoolie bass	Around structure and in open water	Small paddle tails, 5-10g metals, small crankbaits	Jighead or straight lure, steady retrieve
Flounder	Sandy or muddy patches	Worm worked slowly	Carolina or jighead

Lesser weever turn up on LRF gear too, and their spines are venomous. Step 8 covers handling, and the weever fish guide covers identification.

Bass are a bonus on light tackle; to target them properly, see bass lure fishing. Street Fishing London doesn’t recommend targeting big ballan wrasse on LRF tackle, because they can overpower it.

If you are unsure what lives on a mark, start on the bottom with a drop-shot worm.

Step 6: Pick a Sheltered Mark and the Right Time to Fish

Cast into open, featureless water and you will often blank. LRF fishing works because the fish live tight to structure.

Look for:

harbour walls, pillars and pontoon edges
rocky gullies and weed lines
groynes and the corners where they meet the shore

Sheltered harbours are the best start and suit families on calm days. Pier fishing works the same way. Once you have a few sessions behind you, fishing from rock marks opens up more ground.

Spring to autumn gives the most variety. Winter still produces at deeper harbour marks, where rockling, pouting and resident wrasse remain. Rockling are semi-nocturnal, so dusk and dark tend to suit them better than bright sun.

No single tide rule fits every mark. Low light and moving water are often productive, but the best state of tide differs from wall to wall, so note what works on yours. Tides for sea fishing explains the basics.

Stay safe:

Follow harbour signs and closures, and keep clear of working boats and moorings.
Avoid wet, weedy steps and wave-washed rocks.
Check tide times so you can’t be cut off on a rock mark.
Consider a lifejacket on exposed walls.

The fishing safety guide goes further. For a first trip, choose a sheltered harbour wall and leave exposed rock marks for later.

Step 7: Check the Rules Before You Keep Anything

You don’t need a rod licence to fish for ordinary sea species in England and Wales. In England, any bass under 42cm must go back.

The GOV.UK rod licence page covers salmon, trout, freshwater fish, smelt and eel, not sea fish. In estuaries where salmon, sea trout or eels could be caught, check first (see our fishing licence rules). Scotland and Northern Ireland set their own licence and bass rules, so check with the Scottish Government or DAERA.

For bass in England, the MMO’s bass fishing guidance on GOV.UK (updated 27 February 2026) sets these rules for shore and boat anglers:

Rule	England
Minimum size	42cm
1 February to 31 March	Catch and release only
Rest of the year	Up to three bass per person per day

Welsh guidance has been worded differently, so check gov.wales. More in bass fishing regulations.

Local byelaws apply on top. Devon and Severn IFCA, for example, says rock cook wrasse cannot be removed from a fishery in its district. A recreational pollack limit has also been reported for some sea areas, so check the MMO guidance on GOV.UK before keeping any.

Most LRF fish go back anyway. Before you keep anything, check GOV.UK and your local IFCA.

Step 8: Fish Your First Session, Read the Bites and Look After the Catch

Two beginner mistakes cost more LRF bites than any others: too much rod movement and too big a lure. Fix those first.

Rig a light jighead or drop-shot from Step 4.
Drop it close to the wall rather than casting as far as you can.
Let it settle on the bottom.
Give it tiny lifts and shakes, then let it sit still for a moment beside structure.
Watch the line and rod tip for taps, plucks or line falling slack, and lift smoothly rather than striking hard.

Rattling bites from mini species often mean a fish has hold of the tail only. Pause before you lift, or drop down to a smaller lure or hook.

Small hooks can go deep in small fish, so set yourself up for fish care:

Use barbless hooks or crush the barbs.
Carry forceps for deep-hooked fish.
Use a short-handled rubber-mesh net on higher walls.
Wet your hands and keep fish out of the water for as little time as possible.
If a hook won’t come out easily, cut the line close rather than tearing it free.

Lesser weever carry venomous spines on the back and gill covers. Handle them with forceps or a cloth, never bare-handed, and get medical advice from NHS 111 if you are stung.

After each session, note the species, rig, lure, tide and conditions to learn what works on your marks.

Slow down and scale down before you change anything else.

Frequently asked questions

What does LRF stand for?

LRF stands for light rock fishing. It means ultra-light lure fishing in the sea with lures of roughly 7 or 8g or less, usually around harbours, piers and rocks. The style came from Japan, and UK anglers use it for everything from gobies to pollack.

What is the difference between LRF, light game and HRF?

The difference is lure weight and target size. Street Fishing London defines LRF as lures up to about 7 or 8g. Light game steps up to heavier lures for bigger fish such as bass and pollack. HRF (hard rock fishing) targets larger fish over snaggy ground with much stronger gear.

Can I use my perch lure rod for LRF?

Often, yes. Street Fishing London says perch lure rods, reels and braid can double for LRF. Check the rod's casting weight suits lures of roughly 1-7g, and rinse everything in fresh water after a sea session. A rod built for heavier perch lures will struggle with sub-2g jigheads.

Is LRF worth doing in winter?

Yes, at deeper harbour marks. Rockling, pouting and resident wrasse stay through winter, and dusk and dark suit rockling best. Expect fewer species than from spring to autumn, and fish slowly on the bottom with a scented plastic on a light jighead.
