How to Fish a Maggot Feeder

By Alex Clayton · Updated 23 October 2026

A maggot feeder is a small feeder, usually a block-end, filled with loose maggots that crawl out on the bottom right beside your hookbait. Fish feeding on the free maggots find the one with a hook in it.

The catch is that most advice online is split by species, and it contradicts itself. One guide uses a 4in hooklength for roach and tench, another 3 to 4ft for river chub. Both are right, because they are different rigs doing different jobs.

The five steps below run from choosing the feeder to fixing missed bites, for roach, bream, tench and chub on rivers and stillwaters. If you are new to the wider method, start with our guide to feeder fishing.

Step 1: Choose a Block-End or Open-End Feeder

One choice decides whether your maggots trickle out steadily or land in a heap, and it comes down to which end the feeder has.

Feeder	How it releases	Use it for	Avoid it for
Block-end feeder	Closed at both ends with a lid to load; maggots crawl out slowly through the holes	Loose maggots on their own, so fish compete for a steady trickle	Groundbait
Open-end feeder	Open at both ends; maggots or casters sealed in with groundbait plugs	A bigger hit of feed, or groundbait and maggots together	Loose maggots alone (they fall straight out)
Cage feeder	Open mesh that holds compressed groundbait or pellets	Groundbait-only feeding; see our cage feeder guide	Loose maggots

A blockend feeder is also easy to convert into an inline feeder, which matters for the bolt rig in Step 2. An open end feeder earns its place when you want a cloud of groundbait to pull fish in, with maggots inside to hold them.

On a stillwater, use just enough weight to reach your spot. On a river, go heavier until the feeder sits on the bottom without rolling downstream. For one published example, a Drennan news item describes a 35g feeder cast about 40m on a reservoir for bream. That is one set-up, not a rule.

Hole size changes the release rate too. Fewer or smaller holes slow the trickle for cold water and small fish, while bigger holes empty faster for warmer water and bigger shoals.

If you are fishing loose maggots on their own, start with a block-end. Before you buy several pints, check that the fishery allows maggots at all (see the FAQ).

Step 2: Tie the Rig, Running or Inline Bolt

Why does one guide fish a 4in hooklength and another 3 to 4ft with the same feeder? Because there are two maggot feeder rigs worth knowing, and they hook fish in different ways.

Inline bolt rig (short hooklength)

The bolt rig uses the feeder’s weight to set the hook as the fish moves off.

Thread an inline feeder onto your main line.
Tie a snap link swivel to the end of the main line, below the feeder.
Push the swivel into the end of the feeder so it sits as a friction fit. It should pull free under pressure, making the rig semi-fixed rather than fixed.
Clip on a short hooklength, around 4in (10cm).
Fill the feeder and cast.

For river roach, Angling Times describes converting a block-end to inline and using about 10cm (4in) of 4 to 6lb fluorocarbon.

Dave Robinson, writing in Angling Times, recommends running elastic through the inline feeder. It cushions the fight and cuts down hook pulls, which short hooklinks are prone to.

Running rig (longer hooklength)

Here the feeder sits on a link or swivel that slides freely on the main line, stopped above the hooklength swivel by a bead. A fish can move off with the bait before it meets the weight of the feeder.

For river chub and barbel, the Angling Times guide uses a 3 to 4ft hooklength, up to 6ft in clear water, on 10lb main line. On stillwaters, the Drennan bream example used 18in of 0.14mm line.

Keep it safe

Avoid fixed set-ups on weedy or snaggy venues, and fish an inline rig only on a firm bottom, not silt or weed. Whatever you tie, make sure the feeder can slide off if the main line breaks, so a fish is never left tethered.

Use the bolt rig where fish bite confidently and you want a better hook-to-bite ratio. Use the running rig where fish are wary or the river runs clear.

Step 3: Match Hook, Hooklength and Bait to the Water

One Angling Times river writer says the maggot feeder has fallen out of favour with most river anglers, then spends the rest of the guide using it for chub and barbel. It is no longer the default, but it still catches when conditions suit it.

The method is the same on rivers and stillwaters. What changes is hook size, hooklength, line and where you cast.

Species	Water	Hook	Hooklength and line	Bait	Where to cast
Roach	River	Size 14 or 16	About 4in (10cm) of 4 to 6lb fluorocarbon, bolt rig	Maggot	Steady, even-paced glides
Tench	Stillwater	Size 12 or 14, medium gape	Short, as little as 4in, inline	3 or 4 maggots	Firm bottom near lilies and weedbeds
Chub and barbel	River	Size 14	3 to 4ft, up to 6ft in clear water; 10lb main line	Maggot	Snags and flow edges
Bream	Stillwater or reservoir	Size 16	18in of 0.14mm (one example)	Red maggots	At distance, about 40m in the example

Treat these as starting points from published guides, not fixed rules.

Feeder fishing for roach on rivers is where the bolt rig earns its keep, and the Angling Times roach guide credits it with a better hook-to-bite ratio. Our river fishing guide covers reading the swim before you choose a line.

Bream are different. On Windermere I’ve found that bream tend to move through in groups, so a steady feeder line that keeps a little bait going in is more useful than one big hit.

For buying and storing bait, see our guide to maggots and casters.

The maggot feeder suits swims where you want to feed little and often. Skip it where small fish strip the maggots before anything bigger arrives, or where the fishery bans them.

Step 4: Fill, Cast and Build the Swim

Two hours, a pint of maggots gone and not a knock on the tip. Usually that is because every cast landed somewhere different, and the feed is spread over half the lake.

Fill it properly

Do not pack a block-end solid, or the maggots cannot crawl out. Fill it loosely and push the lid on firmly. Hook your maggots lightly through the blunt end so they stay lively.

Cast to the same spot every time

Pick a marker on the far bank and cast towards it.
Once you reach the distance you want, clip the line on the reel spool.
Cast to the clip every time, and feather the line just before the feeder lands so it drops in quietly.

Find a rhythm

Cast more often early on to build a bed of feed. The Angling Times chub and barbel guide recasts every 4 minutes at the start. Once bites come, ease off so the fish compete for a small amount of bait rather than filling up.

After each cast, sink the line, set the rod so the quivertip sits at an angle to the line, and tighten to the feeder until the tip has a slight bend.

Rivers versus stillwaters

On a river, the current carries spilled maggots downstream, so your hookbait should sit at or just below where the feeder empties. On a stillwater, the feed stays where it lands, so over-feeding is the bigger risk.

Accuracy first, quantity second. A pint of maggots spread across the lake does less than a handful landing on the same patch every cast.

Step 5: Read the Bites and Fix What Is Not Working

When you are missing bites, change one thing first: the hooklength. Most maggot feeder problems show up on the quivertip, and each fix below changes a single thing.

Lots of taps, few fish hooked: shorten the hooklength or switch to the bolt rig from Step 2. Angling Times notes the bolt rig improves the hook-to-bite ratio.
Few bites at all: lengthen the hooklength so the bait behaves more naturally, then scale down the hook and bait.
Hook pulls on a short hooklink: add elastic through the feeder, as Dave Robinson suggests.
Cold water: common practice is fewer maggots per cast, casting less often, and a smaller hook with a single or double maggot. Fish are less active and need less to fill up, so overfeeding kills a cold-water swim quickly.
Feeder rolling on a river: step up to a heavier feeder until it holds.
Fish running into weed: keep steady pressure, and never fish a fixed rig in weed. Use the semi-fixed inline set-up from Step 2 so the feeder can come free.

Look after what you catch. Wet your hands before handling, unhook on a mat and return fish quickly, especially tench and bream that have fought hard in warm water.

If bites dry up after a good start, cut back the feed before you change anything else.

Frequently asked questions

Can I use a maggot feeder at any fishery?

No. Some venues ban or limit maggots. Angling Times reported that Berners Hall bans them from March to October, Bluebell Lakes bans them outright and Linear Fisheries limits anglers to 4 pints a day. Rules change, so check with the fishery before you travel.

Are maggots allowed in Northern Ireland?

Only on listed waters. Byelaws 6 and 7 of the Northern Ireland fisheries byelaws (SR 2005/267) prohibit using or possessing maggots or groundbait while angling, except where allowed. Check the nidirect table of DAERA waters to see which permit them before you fish.

Can I fish a maggot feeder on rivers in spring?

Not for coarse fish in England from 15 March to 15 June inclusive. The close season covers rivers, streams, drains, some canals and some SSSI stillwaters, according to GOV.UK. Most stillwaters stay open. See our fishing seasons guide.

Do I need a licence to fish a maggot feeder?

Yes. In England you need an Environment Agency rod licence from age 13, and licences for 13 to 16 year olds are free. At the time of writing, a 2-rod coarse and trout licence costs £7.30 for 1 day, £14.70 for 8 days and £36.80 for 12 months. Prices change, so check GOV.UK before you buy, and see our fishing licence guide.
