Peeler crab have a well-deserved reputation as one of the best sea angling baits. The most sought after fish in British waters such as bass, large cod, smooth hound and big rays can all be caught with peeler crab, while other species such as coalfish, flounder, eels and plaice will all also go for peeler crab baits when other baits prove ineffective. The scent trail that peeler crab emits attracts fish from a wide area, with even small amounts of peeler crab, such as legs or claws added to a worm bait, being enough to give anglers using this bait an advantage. The effectiveness of peeler crab means that it can demand can often outstrip supply and tackle shops and online bait retailers often struggle to maintain a regular supply of peeler crab throughout the year. Peeler crabs can be found around shorelines across the UK, although anglers must know what to look for and the be prepared to spend time collecting this bait.
What is a Peeler Crab?
Peeler crabs are not a specific species of crab – it is a process crabs go through when they cast off their old shell in order to grow a new larger once. For a short period between the loss of the old shell and the hardening of the new shell the crab will be classed as a peeler and be useful as bait.
Any of the species of crab with are found around the UK can be used as bait when they are in the peeler stage, although as the common shore crab is the most common this is the most likely to be used.
The Peeler Process
All species of crab have soft internal organs which are protected by a hard outer shell. As the crab grows it becomes too big for its existing shell and absorbs water, making its body expand and causing the shell to crack, split and eventually fall off to reveal a new, larger shell underneath. However, this shell is soft and weak and takes a few days to harden. Knowing it is vulnerable during this time the crab will hide under rocks and in crevices until it is protected once again by a hard shell. Once this process is complete the crab will leave its hiding place and begin to hunt for food again.
Generally the best bait is gained from crabs with the old hard shell still on their backs, but falling away (the fact this shell needs to be peeled away gives this bait its name). Crabs which have recently lost their shell and only have the new soft shell are know as softbacks or leatherbacks and, although not as good as a genuine peeler, they are still a useful bait if their shell is very soft. Crabs with a normal hard shell that are actively feeding (i.e. the ones sometimes reeled in when they are feeding on fishing baits) have a limited use as bait.
Collecting Peeler Crabs
Many anglers gather their own supply of peeler crabs by searching around rocky shorelines for crabs which are in the peeler process. Overturning rocks (always return them to their original position) can reveal hiding peeling or soft back crabs, as can cracks and crevices between rocks, especially those covered with weed. The edges of rockpools can also be areas where peeler crabs hide.
When a crab is found a splitting shell or one which is falling away from the body will reveal a genuine peeler crab which is suitable for bait. An easy way of checking whether or not a crab is a peeler is to do the leg section test. This involves pulling gently at the end section of the crabs back leg. If this section comes away easily to reveal a soft section underneath the crab is a peeler and suitable for bait. If the section stays in place the crab is not at the right stage to use as bait and should be left alone.
If the shell is very soft it is a leatherback and still useful for bait, but, as stated, if the shell is in its normal hard state the crab will be if very limited use as bait with only a few species such as wrasse and smooth-hound being regularly caught on hardback crabs. Generally, hardacks should be left alone, as they will eventually become peeler crabs themselves. Generally it is spring when the vast majority of crabs start to peel, and the warmer summer months can provide a decent supply of crab bait. Once the cooler weather arrives in the autumn crabs stop peeling and anglers will have to wait for the following spring to gather more peeler crabs.
Anglers finding crabs which are berried (carrying eggs underneath their body) should leave them well alone as they will be on the verge of releasing eggs which will repopulate the area and ensure a supply of future peeler crabs for anglers and food for fish. Indeed, in some areas local by-laws and legislation make it an offence to collect a berried crab. The same applies if a small female crab is found sheltering under a larger male crab.
Many anglers create artificial havens for sheltering peeler crabs by placing tyres, tiles or paving slabs on riverbanks or in sheltered harbours between the high and low water mark. These can be checked regularly throughout the summer months and can produce a supply of peeler crabs. Peeler crab traps which have been set by other people should be left alone as people will not react well to seeing traps they have set being emptied by other people.
Restrictions of Collecting Peeler Crabs
Be aware that there can be restrictions on taking edible (brown) crabs for use as bait. In some parts of the UK by-laws can restrict the collection of edible crabs by imposing a minimum size limit, or ban their collection altogether. As mentioned there are also laws restricting the collection of berried crabs. Anglers should find out what the regulations are in force in the area where the crab-collecting will be carried out and follow them, as they are there to protect crab populations and ensure that numbers remain sustainable.
Buying Peeler Crabs
Peeler crabs can be bought from most fishing tackle shops throughout the spring and into the summer, although demand often outstrips supply and many tackle shops sell out. Peeler crabs are not cheap and usually cost around £1 each. However, weather conditions, seasonal variations and the ability of bait gatherers to get out can all interrupt supply, and if a low number of crabs is available to the bait shops the price of peeler crabs can be pushed up. In winter live peeler is not available, but frozen peeler crab may still be sold although this can also sell out in the winter months. Online bait suppliers can send frozen peeler crab through the post with English crab costing more (and being a better bait) than foreign varieties they also offer. Again, frozen peeler crab is often out of stock from online suppliers during times when demand is high.
Storing and Freezing Peeler Crab
Peeler crab can be stored live in plastic trays in the fridge. However, this is difficult, complicated and time consuming, as it requires aerating the water with equipment which is usually used in fish tanks. Furthermore, if a number of crabs have been gathered then they will all be at different stages of peeling, meaning some may revert to hardbacks before they can be used as bait. For this reason it is best to use live peeler crabs soon after they have been collected or purchased. Luckily for anglers peeler crabs can be frozen, and lose very little of their effectiveness during the freezing process. Once peeler crabs have been prepared (see below) the peeler crab bodies, legs and claws should be placed in the freezer on a plate or chopping board for around fifteen minutes. After this time they will be partially frozen and should be removed from the freezer and wrapped in clingfilm – peeler crab bodies can be wrapped individually, while legs and claws can be wrapped in bunches of four or five. When frozen in this way peeler crab will keep for at least two years in a domestic freezer.
Preparing Peeler Crab
Whether a peeler crab is being prepared to use as bait or freeze for future the same process is followed. First it should be killed humanely by piercing it between the eyes with a narrow bladed knife. Remove the legs and claws by twisting them away from the body. Do not throw them away as they are also usable as bait in their own right. Next peel the crab by removing the main shell from the back of the crab and work the way around removing the shell from the rest of the body one section at a time until the shell comes off completely.
The lungs of the crab are located on either side of the body. They are sometimes referred to as ‘dead man’s fingers’ and are usually removed by anglers and discarded. Other smaller sections of shell can be pulled away from the underside of the crab to complete the peeling process. The crab body is now ready to be mounted onto the hook if it is being used fresh, or frozen if it is being kept for future use. Crab legs and claws can be peeled by pulling away each segment of shell off the claw or leg (it should come away easily if the crabs are at the peeler stage). After this is done the legs or claws are then also ready to use as bait or be frozen.
When targeting big cod, bass and rays it is best to use a single large peeler crab body (or two smaller ones) in order to provide a bait large enough to attract these species. When fishing for smaller species large peeler crab can be cut in half to produce two baits. Whichever is used it is best to push the point of a hook through a leg socket of the crab, through the body, and then back out through another leg socket as this is the most secure way of hooking this bait.
Alternatively the hook can be pushed through the back of a crab and out through a leg socket. Hooks with a wide gape are the best for presenting crab baits with several manufacturers producing specialist crab hooks designed for presenting this bait with Kamasan’s B900c pattern being one of the most popular with UK anglers. Since peeler crab is a soft bait and it is essential to use bait elastic – such as standard or elasticated Ghost Cocoon Bait Thread – to attach it securely to the hook. No angler wants valuable peeler crab parting ways with the hook before it hits the water.
Legs and claws can be hooked in threes and fours and secured with bait elastic to produce baits for flatfish and smaller species. It is often a good idea to protect crab baits by incorporating a Breakaway Impact Shield into the rig as this helps ensure that the bait is in the best condition once it is at the seabed. Sections of large crab or whole small peelers can be combined with any other sea fishing bait to produce a cocktail. Peeler crab and ragworm, lugworm, mussel, mackerel or razorfish would all make excellent sea fishing baits. Legs and claws can be also be used to tip off worm baits.
