There are white claw breeding centres, so I don't see why there are such stringent restrictions on the trapping of crayfish,especially in areas overrun by signals. How much of a dent it would make in

Well if they became plague proportions like the Crays, then they could be harvested for the fur trade. Make everyone some nice gloves and hats to combat the cold winters.

?   Apart from just about every fish, water bird and water mammal?

They slow down a lot once it gets really cold but some still seem very active and I have caught Crays ine the depths of winter although that may well be the Vilrile crays that inhabits my local waters and not the Signals. Your chances of using softer baits does increase once it gets cold and the waters are gin clear. In better wheather they are on your baits in minutes.

 

Cannibal, the skill is in devising ways to be able to fish and avoid them. For anyone who might be interested in catching them any method and any bait seems to work. I have yet to find a bait that they are not interested in, even fishing unflavoured plastic they will try and wittle it down. They really are a pain in the..........

I've heard of global warming, but didn't realise it was so far advanced that Kennet signals come ready-boiled ! :)

They are very easy to catch, or rather very hard to avoid. When they're active and feeling bold there's vert little you can do to be honest. I've even seen 2 caught on one cast, one hanging onto the bread hookbait, the other hanging onto the splitshot weights...!

 

After a while you get to recognise crayfish bites. The best thing to do is just reel slowly in when one's on your bait, it normally just hangs on all the way in. Crunch it underfoot, unhook it, chuck it down the edge.

 

They do get nervous around bigger fish as they know they're liable to be eaten, so if they are very quiet when you start fishing it often means the fish you're after (chub, perch) are out and about, and if they're being a pain but suddenly go quiet, it often means some decent fish have just arrived.

 

They are still active in colder weather, but generally the colder the water, the less active they are.

And those who were seen dancing were thought to be insane by those who could not hear the music

These are posh Kennet signals, they're very accommodating.

It's never a 'six', let's put it back

I never knew other fish preyed on them , till i read it in an earlier post,I would imagine they would take a bit of

swallowing ,Or do chub & perch rip them apart to eat them.

Anyone ever heard of pike eating crayfish ?

Pike, chub, perch, barbel, carp and I think even tench could manage them, depending on size. Most fish will just crush them, with their pharyngeal teeth, but I think pike and perch are able to just take them down whole.

Angling is more than just catching fish, if it wasn't it would just be called 'catching'......... John

They're a tremendous source of easy to catch, highly nutritious food for many fish (and mammal and bird) species.

 

Skip to 3.05 to see how even a decent size cray is an easy dinner for a pretty small perch:
