The one’s you catch are the regular wild colors but crayfish and freshwater shrimp ( not ghost shrimp ) are not difficult to breed for color so the Australian Yabby here is sold in different colors .
Different color Australian crayfish here are so popular that there is a site Aquatic Arts ( I used to sell him shrimp ) which sells color variations of Australian and Indonesian crayfish , he sells out left and right
Signal crays are an absolute pain in the arse on this side of the pond
I’ve tried several times to get a permit to trap the little sods from the Environment Agency. The EA aren’t processing applications anymore, better things to do (I hope) tory cut backs perhaps?
My understanding is that if I pulled a few of the little horrors out of my local pond for a tasty treat in the kitchen then I’m liable for a fine of up to two grand!
Work that one out!
Australian wild life as far as reptiles , invertebrates were imported legally and illegally exported into the USA in 70’s early 80’s and as you know birds way before but now forget it .
There is a self cloning crayfish sold here called Marmorkrebs which I wanted to send to a fish friend in UK but found out prohibited there however to late –
''When the self-cloning marbled crayfish was first discovered in the aquarium trade, there were immediate concerns about its potential to wreak havoc on local ecosystems. Sure, they’re incredibly interesting to scientists, but only one has to get out in order for a population to be able to establish.
As the authors of the first paper on the species mentioned back in 2003, a wild marbled crayfish population would be able to spread like wildfire. It would likely outcompete native species and possibly spread a deadly (to crayfish) plague in Europe.
Lo and behold, that’s unfortunately exactly what happened. These crays are everywhere in Europe now, and they’re also found in a number of places in the rest of the world. They’re particularly common in Madagascar, for example, although it has to be said that the locals make handy use of their rapid spread by simply eating them.‘’
I get the bigger picture, I just want a few for the frying pan, not a lot to ask!
I draw the line at mitten crabs! 
That’s one possible reason of many others. Yet it wrongly assumes that almost all people want to make a career. Often people realise that they aren’t carved out for the job that they carelessly took up aged 15 or 16. My mother chose the job for me since I didn’t make a move at all. Unfortunately , she was wrong. I tried to rectify her decision but failed. A friend of mine simply couldn’t work out the maximal floor load. The responsibility was too big for him causing him sleepless nights. And there are many other reasons why people want to get out of that rat race. What they get is cynical remarks made in hindsight like “You should’ve been more careful about what job to pick” or wise adages like “Choose a job you like and you’ll never have to work a day in your life.”
Whenever one seeks to generalise, it goes wrong. There’s no one-size-fits-all solution here. Nor is there a social norm for taking retirement. It’s a purely personal decision taking into account a number of things but not necessarily the biological age. The system should be kept flexible allowing everyone to retire at a time that feels right for them.
There is you, your desire to survive, your will / drive to persevere, that is all you need. If you are not physically / mentally incapacitated, have the drive, want the education / training, want it bad enough, you will find a way, if you don’t; you did not want it bad enough. Been there, done it, “got the tea shirt”. There are far too many who came from places similar to me, we found the way. Life is never a cake walk, nor meant to be.
I could be mistaken but think you have 2 types mitten crabs there , native Australian and non native Asian mitten crab ?
Tell that to a feral Animal who needs to survive. Evolution or creation!!
Working is not just a job it is a social event too (though I suppose there are some people who work by themselves). I certainly enjoyed the social aspect as much as the job itself.
Over the years have had a number of jobs even been self employed, some jobs were temporary fill in jobs just for the money but generally speaking I have enjoyed working even those jobs. I did retire early at sixty because I could and because I had things I wanted to do, not because I disliked the work.
Does anybody really dislike a job they keep at? I doubt it. I don’t think working life is as miserable as you make out.
I never intended to make Work sound miserable, quite the opposite
Sorry I thought you were subscribing to Henry David Thoreau’s: ‘The mass of men lead lives of quiet desperation.’
Amen, and that is what everyone misses.
The cricket season 
No Ball Tampering 
“Hanging on in quiet desperation is the English way” 
Same here. I will now have the opportunity to attend more cricket matches. 
Not your decision.
The Captain will decide when the sandpaper will be brought on for it’s turn. 
… just Roger Waters being miserable again.
I also have enjoyed all the jobs I did during my working life and the friends I made (I miss the banter) there were short interludes of desperation, but they soon passed, and not usually caused by the job I was doing.
I feel that I made the right choices in life and still are…
Same here. Once or twice during my varied working lifetime I took a wrong turn, found myself doing something I was not cut out for.
But 90 something % of the time I was, well, having fun.
