Catching Crayfish

North American Signal Crayfish
Crayfish are a wonderful delicacy, and in the right locations you can catch 20 to 30 in a couple of hours by simply tossing a trap into water where they’re present. Please be aware that you need a license to capture native white clawed cray fish. In many waterways, an invasive species, North American Signal Crayfish are also present, and these are a pest. They spread a disease which harms native stocks, and damage river banks and eat salmon and trout eggs.
You need three things to catch non-native crayfish in England and Wales:


1. A lawful trap;

2. The landowner’s permission;

3. Consent from the Environment Agency in England or National Resource Wales (this is free). This application form should be used.

Once your application is approved, you will receive identity tags for your traps and a catch return form. Please be aware that if you catch crayfish without consent and using equipment which does not meet the Government requirements you may be prosecuted. If you catch a North American signal crayfish by mistake and throw it back in the water, this in itself could be a criminal offense. The maximum fine is £40,000 and you could face a year in jail.

If you want to catch crayfish in Scotland, contact Marine Scotland on 0300 244 4000. North American signal crayfish are still relatively rare in Scotland, and licenses may be more difficult to obtain than in England. If you’re going to catch them, do it legally. The risk to the environment from breaking the law (and to you personally if prosecuted for unlawful trapping) simply isn’t worth it.

Identifying Species: The colour of white clawed crayfish claws is lighter on the underside than on the top (hence the name) and the claws are smaller relative to the size of its body. The bottom of North American signal crayfish claws are red with a prominent white or bluish patch in the claw joints (and the claws are large!).

Compliant Traps: Crayfish traps must conform to specific criteria. This is to stop other species such as otters from being caught and drowning. Trap entrances must be no more than 95mm wide, be no longer than 600mm, be no wider than 350mm and have mesh no wider than 30mm.

Be cautious of buying collapsible traps online. Some are not UK compliant. I like the Swedish Crayfish Trap, which is! If you want one which collapses for convenient transportation, don’t buy the ‘luxury’ ones online which tend to be too long (over 600mm). Jackal Outdoors sell one which is the right legal length and width.

Baiting Crayfish Traps: Fish heads, cat food or even salami is used. Most crayfish nets have a small zipped or drawstring bag for you to put the bait in. You’d be amazed at how many you can catch in some waterways, with 80 being caught by one friend in an afternoon.

Placing Traps: In the South of England, crayfish have spread all over the river system. You’ll find it easier to get a license in the south than in the north or Scotland. Place the baited trap in the water course (some take a can of cat food, drill holes in it and use that as the bait. Weight it down with a couple of stones inside to stop it floating away. Tie a length of paracord to the net and stake the other end down firmly on the river bank. It really isn’t harder than that. Come back and check in a few hours. Make sure you wash and disinfect the trap thoroughly to stop the risk of transferring crayfish diseases to other water courses.

Preparing Crayfish: Boil them, skewer them and cook over a campfire, or put straight onto a barbecue. Mr Mears shows you how to humanely despatch them in the video below. You’ve done the difficult part… you’ve got your license, get permission from the land owner, bought a suitable trap, waited patiently… was it worth the effort? For a bucket full of baby lobster… HELL YES!
