How the fuck am I meant to find where these fuckers are in the UK???
I want to help do my part and get some tasty morsels while at it but it feels like it's impossible to find which rivers/streams these fuckers inhabit.

>>2831144 (OP)
Dunno about UK but the little bastards are in just about every single river here in the US, pick a rock up along the shore and you're almost guaranteed to find one.

If you have the ability to, toss a trap in the river at a bend where it's slower and wait, possibly even coming back the next day. If there's crawdads in the river they will get caught.

Yeah trapping them is completely free in the UK cause they're invasive. Issue is you can't trap in rivers that also house native crayfish afaik and there's very little sources other than word of mouth on which rivers you can.
My best source so far has been the few reports on Inaturalist

I have a few crayfish traps and catch them in the old pre-ww1 fortification motes near me.
make sure you know the difference between the native species and the invasive ones.

I dont know UK law, here in Denmark you need an upgrade to your fishing license (which i have) to set traps and nets, its essentially a 3 tiers system 1. normal rod and reel license, 2. can do anything a commercial fisherman can, but cant sell 3. commercial
so, is it a blanket ban on setting traps in areas with natives or is it illegal to keep natives? i haven't gotten any natives yet so it hasn't been a problem for me, but here you just return them if you catch them, all invasives must be killed and disposed of (not just killed and thrown back in the river, i prefer disposing of them by eating them)

here is a little picture showing the difference in the species,A. native B. Signal C. Galician.
the signal crayfish has that very distinct marking on the claws, and the Galician tends to be larger, with a different textured shell

i would highly recommend just getting a few folding net traps (check your laws if it is legal for you to leave a trap unattended) they are great fun just to toss a few in while you are fishing anyway, they work great on shorecrabs in the ocean too, which we have a big problem with here because they cause huge ammounts of errosion, but hey, they are tasty and free!

In the UK it's free to apply and get a licence as long as you are only trapping not native crayfish and your traps are regulation (to prevent stuff like otter deaths). But afaik you can't trap in areas where there's both native and non native as you can't trap native at all without a special licence.

Have you fished in canals? Can't move for the cunts in the south.

I live in Australia and when I used to go camping/fishing with my family my grandfather would pullover on the side of the road and butcher a roadkill kangaroo and use it as bait in crayfish traps (we call them yabbies) we would then use them as bait for freshwater fishing in billabongs. There is something about crayfish, they are fun to play with and watch crawl on the ground.
they are good bait for:
>golden perch (yellabelly)
>murry cod

the Tasmanian ones apparently get absolutely massive

>>2831178
They also do in North Queensland, this guy is famous for his /out/ shenanigans in Australia and some of the crays he catches are beautiful. I personally don't live close to the big ones though which is unfortunate, you also have to free-dive to catch them around reefs

>>2831180
but those are salt water

>>2831184
Sorry my cray knowledge isn't 100%

>>2831178
I automatically thought this was a salt water cray due to the size, but if that's fresh water its monstrous. I bet it tastes delicious (if its not protected)

>>2831185
>salt water cray
well, technically, they are, its just most of the world outside of Australia, New Zealand and apparently Ireland for some reason, they are called spiny lobster/rock lobster, etymology gets complicated really quick, ussually the rule of thumb (outside of the countries mentioned) its
fresh water = crayfish
sea = lobster

>>2831185
The Tasmanian giant freshwater crayfish is the largest freshwater crayfish in the world and is endangered, illegal to catch since 1998.

>>2831259
Very impressive anon, would love to see one of the tassy ones in person, I will keep an eye for it when I visit. Everything in Tasmania is a little odd because there are no predators
>fresh water crays go huge
>kangaroo's turning albino
>The platypus's in Tasmania are the only species to walk across land regularly

>>2831161
>you can't trap in areas where there's both native and non native as you can't trap native at all
wait, that makes no sense? how are you supposed to decrease the number of invasives in areas with natives, if you cant, because of the natives? so, you can only help the natives by trapping in areas where ... there aren't any? seems backwards

>>2831301
I could be wrong but that's the way I understand it
