@mikesooty1981 Looks like a Signal crayfish. What part of the country was this?

[Crayfish UK @crayfish_uk]

@ecoevoenviro @PeterGlenser @Wildflies @BASCnews @AnglingTrust Not much published research but we have first hand experience and accounts

@ecoevoenviro @PeterGlenser @Wildflies @BASCnews @AnglingTrust This, https://t.co/AWbsu5zjwc

@ecoevoenviro @PeterGlenser @Wildflies @BASCnews @AnglingTrust Eggs/larvae/ plague can even be spread by wildfowl, surviving flight 3/3

[Crayfish UK @crayfish_uk]

@ecoevoenviro @PeterGlenser @Wildflies @BASCnews @AnglingTrust Same goes for Crayfish plague, spread easily to different sites 2/3

[Crayfish UK @crayfish_uk]

@ecoevoenviro @PeterGlenser @Wildflies @BASCnews @AnglingTrust Yes to both. Eggs/larvae can survive out of water for a long time 1/3

@PeterGlenser @Wildflies @ecoevoenviro @Potkiln @BASCnews Happy to help https://t.co/hR7CUVWbAS

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln firming up biosecurity 2/2

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln Stopping the spread as best we can, protecting natives and 1/2

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln They're just so prevalent in (mainly) English waters

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln If we found a perfect answer, 60% of the population would remain unaffected 2/2

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln Sadly they'll never be fully controlled. Even with a 'silver' bullet solution 1/2

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln and by larva/eggs spreading on fishing gear, traps, waterproofs 2/2

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln Most signals are spread by human activity, through introductions and 1/2

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln It also has no effect on population control, it can stimulate it in some cases 2/2

[Crayfish UK @crayfish_uk]

@PeterGlenser @Wildflies @ecoevoenviro @BASCnews @Potkiln We dont advocate eating Signals as it risks their spread to unaffected areas 1/2

[Crayfish UK @crayfish_uk]

@samueljameslee1 @ProfJGrey @Wildflies Crayfish can feel pain, show signs of distress. It's an animal and needs to be humanely treated

[Crayfish UK @crayfish_uk]

@samueljameslee1 @ProfJGrey @Wildflies Ensure its instantaneous, splitting lengthways along the carapace with a sharp instrument

[Crayfish UK @crayfish_uk]

@samueljameslee1 @ProfJGrey @Wildflies We would advocate a more humane approach.

@Wildflies @ProfJGrey Here at Crayfish Towers, we've seen some lobster-sized Signals. There are some Krakens out there...
