So I have a common crayfish... not exactly sure of the exact species, but is it possible to breed crayfish? Are some species easier than others, because I would like to try and breed any type of cray? I am wondering how and what needs for it to be done?? Any information would be great!!!! :)
 
Firstly, you will need a second crayfish...preferably of the opposite sex. Also a bit of space is needed. What species do you have at the moment?
 
Most procambarus species are easy to breed. My female P. clarkii (red swamp cray) Is carrying eggs currently. Search on google. I would give you details, but I don't really have time right now. Post a pic and maybe someone can ID it.
 
My friend brought down his male, and they started to mate. A month later, egg cluster was under the female's abdomen. Then, the eggs hatched. She hid in a log with a hole in the top, and I would put shrimp pellets through the hole. The babies got bigger and ate the pellet crumbs. During this stage, I suggest putting nylon cover over the filter, so they don't get sucked up. Many babies made the filter their home, and when I cleaned it out, I had to get them all to safety. The babies grow very slowly. Be patient.

We both had procambarus clarkii, a species in which the males switch "modes" every time they molt. Mode 1 is the mode in which they will mate. Mode 2 is the mode in which they will attack. It is impossible to tell mode.
 
Make sure you have a pipe or cave wher they can hide during the soft molt stage. Fish or other crayfish will eat them otherwise but if they have a pipe they can harden up in safety.
 
Yes indeed some species are easier then opthers to breed. P. clarkii are IMO the easiest. Butmost do readily breed.
But much space is needed. At least 35 gallons to themselves.( thats the smallest they have been in when they did it for me.) Usually i see mine mating but i rarely ever get berried females from this. I did however, when i emptied out my pond find several tiny crays.
 
Hey, thanks guys, well I have him in a 10 right now, but I have a 30 and a 55 that can be used... heres some pics...

Actually, I forgot. Claws are much longer in "mode 1," the mating mode. This crayfish appears to be ready to mate.
 
The long claws are one indication. If your willing to pick him up, Form I males also have golden-brown, cornified tips on their gonopod. It appears to be P. clarkii or a similar species.
